Crafting the perfect essay takes time and dedication. There are so many elements you have to worry about, such as tone, purpose, and correct spelling and grammar. Writing a strong topic sentences is another critical part in writing a cohesive essay. 

Without a strong topic sentence, you risk losing your reader and perhaps part of your grade. If it’s a college admissions essay, then you need it to be as strong as possible to back up your application. Learn about what steps you should take to write a strong topic sentence.

What Is a Topic Sentence? 

People often confuse a topic sentence with a thesis statement. A thesis statement is typically at the end of your opening paragraph, that dictates the main argument you’ll be making in your essay. 

Throughout your essay, you’ll have multiple topic sentences, as each paragraph should start off with one. This beginning sentence is used to direct the topic of the paragraph and outline the flow of the following sentences. It’s used to help guide your reader and to continue to keep them hooked on your overall essay. Without topic sentences, your essay will be unorganized, lack transitions, and sound very choppy. To write a good topic sentence, there are several steps to take.

Writing a Good Topic Sentence: 5 Steps

Step 1: decide what you’re going to write about..

When you see the essay prompt, you’ll have some time to think through what you want to say and why. You have to decide if it’s a persuasive essay, informative, narrative, or descriptive. Determine your purpose for writing the essay after reading through the prompt. Whether it’s an assignment for school or if it’s to get into college, you need to make sure you have that purpose clearly outlined. 

Step 2: Create a thesis statement.

One of the first things you need to do is create a thesis statement. This is typically a sentence with three points that you’ll back up throughout your essay. 

For example: The Office became a cultural phenomenon because it spurred the careers of many of today’s successful movie stars, it talked about situations that most American workers can relate to, and even 15 years later, offers funny, relevant content that helps to break down prejudices. 

You then use that thesis statement to create an essay around the points you want to make. 

Step 3: Make your essay outline.

Once you have the points you want to make within your thesis statement hammered out, make an outline for your essay. This is where you’ll start to create your topic sentence for each paragraph. You want to clearly state the main idea of that paragraph in the very first sentence. From there, you back up that main idea with facts and reputable sources. Make sure your topic sentence is clear, but does not just announce your topic. 

For example, do not write something like: “In this paragraph, I will discuss why it’s bad that poachers are killing giraffes.”

Instead, write something that clearly states your idea with a reasonable opinion and that gives direction to the paragraph: “Giraffes are a key part of the African ecosystem, so it’s important to enforce regulations against the poachers who are killing them for their body parts.” 

You’d then follow that up with reasons why giraffes are a key part of the African ecosystem and how poachers are destroying their population.

Step 4: Begin writing your essay.

Once you have your thesis statement and you’ve created an outline with supporting paragraphs and their topic sentences, you can begin writing your essay. It’s important to make that outline before just jumping in–a disorganized essay can spell disaster for you as you continue to write, and could result in a poor grade. Many times, teachers will even require you to turn in your outline as part of your overall essay grade. 

Step 5: Proofread and check your resources.

After you’ve written the essay, go back through it with a fine tooth comb. Read through each topic sentence and the paragraphs that follow to ensure that you’ve written clear, solid topic sentences throughout and that the paragraphs with them make sense. During the proofreading phase, you also need to recheck the sources you’re using. Make sure each source is reputable. In other words, do not use sites like Wikipedia where anyone can go in and edit an article to add misinformation. Use sites that:

• Are actual reputable news sources, such as the New York Times , CNN, CBS News
• Have domain names that end in .edu or .gov
• Come from an encyclopedia, such as Encyclopedia Britannica

Using sites that are not reputable could jeopardize the validity of your argument.

Now that you know the steps to set yourself up for success when writing a topic sentence, there are certain elements that go into a quality first sentence. Always make sure that your topic sentence is the first sentence of a paragraph. You don’t want to make your reader hunt for the point you’re trying to make. Check out some key elements of a good topic sentence:

Make sure your topic sentence isn’t too vague.

You need a topic sentence that has some specifics to it. It also needs to hook in your reader in some way with an opinion. A vague sentence makes it harder to write a paragraph that can clearly backs up your thoughts. For example:

DON’T: “In Pride and Prejudice, Mr. Bingley seems like a nice guy.”

DO: “When Mr. Bingley is first introduced, he comes across as a kind person because he speaks to everyone and doesn’t immediately pass judgment.”

Choose a reasonable opinion.

Your topic sentence should clearly outline whatever point you’re trying to make in the paragraph, but you want to pick a reasonable opinion that you can easily reinforce with facts and statistics. Here’s an example of what you should and should not do:

DON’T: “It’s obvious that Mr. Bingley was a total loser with no backbone.”

DO: “Mr. Bingley could have shown more confidence in his choices and stood up to Mr. Darcy when he found himself in love with Jane Bennet.”

You can then back that up with facts, saying that he was a wealthy Englishman and thus one of the key players in society at the time, which should have given him more confidence. If he’d been more confident, perhaps he would not have left and devastated Jane.

Use your topic sentence as a transition.

Along with telling the reader the point of your next paragraph, your topic sentence should also serve as a transition from the previous paragraph. Without a transition, the essay can feel like it’s choppy and disjointed. For example:

DON’T: “Mr. Bingley is a good man and here’s why.”

DO: “Although Mr. Bingley did break Jane’s heart by leaving, he ended up redeeming himself by returning to Netherfield Hall.”

Keep your topic sentence short.

A long, drawn-out topic sentence can risk losing your reader. Many times, it’s hard to determine the point of a sentence when it goes on for too long. You want a clear, concise sentence that draws in the reader but also leaves some room for you to expand on it in the following paragraph.

DON’T: “Throughout the novel of Pride and Prejudice, Mr. Bingley was often quite different from Mr. Darcy as he would treat all people in a friendly manner, considering them all his friends and acquaintances, even agreeing to throw a ball after Elizabeth’s sisters rudely demanded he do so and was gracious to Mr. and Mrs. Bennet as well despite their manners.”

DO: “Overall, Mr. Bingley served as a foil to Mr. Darcy throughout the story by treating everyone around him equally with dignity and grace.”

Writing an essay can be overwhelming at times, but so long as you avoid some of these common pitfalls, it can be easier to get it done on time. 

Don’t wait until the last minute.

If your teacher assigns you an essay or tells you that you have an essay test coming up, don’t wait until the day before to do anything about it. You have to plan or study and you need to give yourself time to do that. If you know it takes you a while to write something, then start planning it as soon as you get the assignment.

Don’t forget to write an outline.

Along with planning, make sure you have that outline written up and planned out well. It will serve as your guideline for writing the essay. Without it, you’ll face the risk of a disorganized essay that does not clearly illustrate your point.

Ask for help if you need it.

This may be the most important pitfall to avoid. If you get in over your head while writing, don’t be afraid to ask for help. Ask a friend to review the essay or ask your teacher for guidance.

Topic Sentence and Paragraph Organization

Paragraph organization refers to the way sentences are structured and ordered to create a unified and cohesive body of text.

The principal features to consider in paragraph organization are the topic sentence and controlling idea, supporting details, organizational patterns, and signal words. Together, these features develop a topic and connect ideas from one point to the next, logically and fluidly. This resource explains these features and provides numerous examples of paragraph organization.

The Topic Sentence and Controlling Idea

Similar to a thesis statement, which establishes the central focus or point of a whole piece of writing, a topic sentence works at the paragraph level to express the focus and general point of an individual paragraph. A topic sentence has two parts: 1) the topic that is being discussed throughout the paragraph and 2) a controlling idea that limits the focus on the topic to one point or idea. Each additional sentence in the paragraph then develops or expounds on that point with supporting details. The example topic sentence below is from a body paragraph in an informative essay.

Example Topic Sentence and Controlling Idea

The economy also plays a role in an increase in prescription pain reliever addiction.

The example topic sentence suggests the paragraph topic is “the economy,” and the controlling idea about the economy is how it “plays a role in an increase” in opioid addition. The signal word “also” connects this topic as an additional example or contributing factor to the opioid epidemic, the focus of the paper. The example below shows the topic sentence in the context of the complete paragraph.

The economy also plays a role in an increase in prescription pain reliever addiction. According to Jungeun Olivia Lee, a social work professor at University of Southern California, “The relationship between joblessness and substance abuse is strongest among people from low socioeconomic brackets, who might not be able to afford healthier ways to relieve their stress” (2017, as cited in Khazan, 2017, para. 8). Additionally, every point the unemployment rate rises, opioid-related death rates rise by almost 4 percent (Khazan, 2017). Unemployment makes it not only difficult for those suffering from pain to afford medication or healthy alternatives, but it can also contribute to depression and varying degrees of self-medication and addiction.

Supporting Details

In a paragraph, the topic and controlling idea are developed with supporting details. Listed here are some types of supporting details found in paragraphs along with an example of each in a sentence.

Facts: statistics or evidence from research that can be verified

• The office sold seven million dollars of real estate during the boom years.

Opinions: statements, quotes, or paraphrases from subject matter experts

• According to expert tea maker, Millie Stoff, there are three easy steps to making tea.

Definitions: explanations of what a term or concept means

• A crossover is a family vehicle with the features of a sedan, a mini-van, and an SUV.

Examples: parts, pieces, instances, traits, or specimens that illustrate the essence or character of a greater whole.

• Mario is a shy, introverted young man. For example, he has few friends and mostly keeps to himself.

Anecdotes: narrative accounts of one time or recurring events

• When I visited the Washington Monument, I enjoyed the 180-degree view the most.

Descriptions: a visual or sensory depiction of a person, place, event, activity, or idea

• Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees.

Example Paragraph and Analysis of the Supporting Details

Hiking can be exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is6,684 feet above sea level. We first crossed a foot bridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

The topic sentence in the example paragraph indicates that the paragraph is on “hiking,” and the focus is that hiking is “exhilarating” during winter. The sentences in the paragraph support and develop this idea with an anecdote of the writer’s experience hiking up a mountain during winter. An anecdote is a narrative account that helps a reader understand an event or situation. Had the writer said hiking was “dangerous” instead of “exhilarating,” the anecdote in addition to the visual and sensory details, facts, and opinions about the experience would have been different. Additionally, while the sample paragraph is a personal account, writers in many professions use anecdotal evidence to report events from an objective point-of-view, where the writer is not a participant but rather a witness or observer.

Paragraph Organization

Along with having topic sentences and supporting details, paragraphs are also organized to achieve a certain purpose. However, just as a paragraph can contain different types of supporting details, a paragraph may also include more than one organizational pattern. Listed here are some common patterns for organizing a paragraph:

• Cause and Effect for showing how one thing leads to another
• Chronological Order for narrating events that occurred over time
• Classification for grouping things together according to their features
• Comparison and Contrast for showing how things are similar or different
• Definition and Example for defining a term or idea and then expanding it with examples
• Description for listing details
• Episode for presenting details or information about a specific event or anecdote
• General/Specific Order for presenting a general idea followed by specific examples
• Generalization/Principle for making a general statement or applying a broad principle to explain the supporting details
• Listing for presenting ideas from least to most important
• Order of Importance for building up to or leading away from the most important point.
• Problem and Solution for presenting an issue and a way to address it
• Process/Cause for explaining what or how something happens and then why
• Spatial Order for ordering details directionally

Signal Words

Signal words are signposts or clues to a paragraph’s organization. If the word “type” is used in a sentence, for example, it signals that the ideas involve types or classification, which is an organizational pattern. Signal words are context clues that hint at what the paragraph is about and how it is organized.

Listed here are signal words associated with different types of paragraph organization.

• Cause and Effect : because, consequently, for this reason, hence, and on account of
• Chronological Order : after, at last, at (time), as long as, at the same time, as soon as, before, during, eventually, finally, in (month or year), later, meanwhile, next, on (day or date), since, second, subsequently, then, until, and whenever
• Classification : categories, classes, classifications, elements, features, groups, kinds, methods, types, varieties, and ways
• Comparison and Contrast : another, both, however, likewise, one difference, on the other hand, on the contrary, similarity, similarly, unlike, and while
• Definition and Example : concept, defined as, described as, e.g., for example, for instance, i.e., illustrates, is, is called, is stated, known as, means, refers to, specifically, such as, term, and that is to say
• Description : above, across, along, appears to be, as in, behind, below, beside, between, down, in back of, in front of, looks like, near, onto, on top of, outside, over, such as, to the right/left, and under

• General/Specific Order : for example, for instance, indeed, in fact, in other words, like, namely, such as, and that is
• Generalization/Principle : additionally, always, because of, clearly, conclusively, first, for instance, for example, furthermore, generally, however, if…then, in fact, it could be argued that, moreover, most convincing, never, not only…but also, often, second, therefore, third, truly, and typically
• Listing : additionally, also, and, as well as, besides, furthermore, in addition, in fact, moreover, or, plus, and too

• Spatial Order : above, below, behind, beside, down, east, feels, highest, looks, lowest, next to, north, smells, sounds, south, tastes, under, and west

Sample Paragraphs and Analyses of the Organization

The sample paragraphs in this section illustrate topic sentences, supporting details, organizational patterns, and signal words in context. Read each paragraph to identify the type of paragraph organization on your own, and then proceed to the analysis to check your comprehension.

Sample Paragraph 1

• In 1995, Lawrence started his real estate business, and it has since become a huge success. When Lawrence Real Estate opened its door in Oviedo, Florida, it sold seven million dollars of real estate during the first few boom years. By 2000, Lawrence decided to open two branch offices: one in Tampa in 2003 and one in Miami in 2004. By 2007, the home office and both the branch offices had survived the economic slowdown, so Lawrence and his associates expanded their business to the Carolinas and opened a branch office in Charlotte in 2020. It can be safely said that Lawrence Real Estate has become a model for success despite economic struggles and real estate devaluation.

Analysis of Paragraph 1: According to the topic sentence, which contains two coordinating clauses and therefore two subjects and two topics, this paragraph is about Lawrence and his real estate business, and the controlling idea is that they have been successful.

To understand how the supporting details are organized to present information about this topic and idea, the reader can consider the supporting details. To do this, they look at the way the sentences begin and at any signal phrases that lead readers along a certain line of thinking. Here are some key signal words: “in 1995,” “By 2000,” “By 2007,” and “in 2020.” These dates make a pattern. They go back to 1995 and then in a chronological order, they move forward to when the success of the business happened.

This paragraph uses chronological order . The reader will notice too that the last sentence returns to the beginning idea of 15 years ago. In this sentence, a final comment about the time period overall is given with respect to the new information

Sample Paragraph 2

• Making a great cup of tea is easy if you follow these three steps. First, heat a cup of water to the boiling point. Then put the tea bag in the hot water, and let it steep for at least three minutes. Finally, add creamer and sugar to taste. There is nothing tastier than a strong cup of tea early in the morning.

According to the topic sentence, which is the first sentence of the paragraph, making a cup of tea is the topic, and the controlling idea is that it’s easy to do if you follow three steps. Signal words open the following sentences: “first,” “then,” and “finally.” These indicate a sequence of steps, not times or dates as in a narrative story, but steps that happen in a specific order as in the process of doing something or informing others how to do something.

This paragraph uses process order (or process/cause). In the last sentence of this paragraph, the process is completed with a return to the original topic—a cup of tea—and a new comment about it—that a strong cup is tasty in the morning, making those three steps not only easy but also worthwhile.

Sample Paragraph 3

• The Washington Monument is divided into three main areas. The lowest section of the building houses the entrance, a gift shop, and a restaurant. The middle section consists of elevators and stairways to the top. The top section of the monument includes an observation deck with a spectacular view of the Washington D.C. area. When I visited the Washington Monument, I toured every section but enjoyed the spectacular 180-degree view the most.

Based on the topic sentence at the beginning of the paragraph, the topic is the Washington Monument, and the controlling idea is that it is divided into three main areas. The paragraph presents information about the lowest section first, the middle section second, and the top section third. The last sentence makes a remark about the most enjoyable of all the sections. This is an example of spatial organization . The information is given in the order you might see it if you were there.

Sample Paragraph 4

• There are three types of family vehicles made in the United States. The first type is the minivan. All American car manufacturers make a version of the minivan. Some say that the comfort and amenities of the minivan compare to none. The second type of family vehicle is the SUV. Some SUVs offer four-wheel-drive to navigate tough terrains, and they also offer seating for a large crowd. A third type of family vehicles is called the crossover. These vehicles supposedly have the best features of the sedan, minivan, and SUV. They are easy to maneuver, look much like a regular sedan, and sit up to six people. All of these vehicles are family friendly; they offer safety, roomy comfort, and many extra features to accommodate the special needs of families.

This paragraph shows another way to organize the details of a topic. The topic sentence of this paragraph is structured differently than the previous ones. Typically, the topic of a sentence is also the grammatical subject, but the subject in this sentence is “there,” a pronoun, and the topic that tells what the paragraph is about, “family vehicles,” is in the predicate of the sentence. The controlling idea is that there are three types made in the U.S.

The paragraph is organized according to those three types: the first type, the second type, and the third type. To conclude, there is a comment about “all of these vehicles” or all of these types of vehicles. When information is organized by types or features, the information is classified. This type of organization is classification .

Sample Paragraph 5

• Although the twin brothers share many physical characteristics, they handle themselves differently in social situations. Mario is a shy introverted young man. He has few friends and mostly keeps to himself. On the other hand, Gino is outgoing and the life of the party. Unlike Mario, Gino has many friends and feels totally at ease among big crowds. The best way to tell these identical twins apart is to invite both to a party and observe how differently they interact with the other guests.

When the topic sentence is complex (having more than one clause) as in this paragraph, there may be two subjects and therefore two topics; however, here, the subject of the first clause is “the twin brothers” and the subject for the second clause is “they,” so both subjects refer to the same topic—the twin brothers. The controlling idea is that the twin brothers share many physical characteristics but handle themselves differently socially.

The paragraph then progresses with descriptions of these similarities and differences. Contrast is created by signal phrases and words such as “although, “on the other hand,” and “unlike.” Words such as “apart” and “differently” also indicate that the organizational pattern of this paragraph is comparison and contrast .

Sample Paragraph 6

• There are many reasons why I enjoy walking tours when visiting new cities. For starters, walking through a city allows the visitor to see the details of an area without having to hurry. This often results in meeting locals and experiencing their lives and traditions first hand. Furthermore, walking tours are flexible and inexpensive because there are no strict schedules or transportation expenses. Travelers taking walking tours are rewarded with firsthand experiences in the places they visit and the opportunity to personally interact with the people who live there.

Because the first sentence begins with “there are,” the reader must move beyond the subject and verb to find the topic. Additionally, this is a complex sentence with an independent and dependent clause connected by “why,” so there may be two topics. Looking at the objects of both clauses, the reader finds “many reasons” and “walking tours.” These two topics are linked together by the controlling idea: the writer enjoys walking tours while visiting new cities for many different reasons.

The signal words build on this idea of “why” with terms such as “results” and “because.” The last sentence then sums up the ultimate effect of walking tours: Travelers are rewarded. This is an example of cause and effect organization.

Sample Paragraph 7

• Hiking can be especially exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is 6,684 feet above sea level. We first crossed a footbridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

In the first sentence, the topic of the paragraph is “hiking,” and the comment or main idea is that it “can be especially exhilarating during snowy winter months.” Based on this, the reader can expect supporting details to illustrate this exhilaration, but they do not know how it is organized until they look at the signal words that help progress the topic from one idea to the next.

Taking inventory of the signal words, the reader will find several time markers: “When” and “last January” set the narrative in the past while “first” and “then” develop a chronological order of events. The final summarizing sentence about hiking “in winter” reminds the reader of the season.

Within this chronology , signal words are associated with spatial organization: “over,” “up,” “beneath,” “through,” “crunched” (sounded), “saw,” “feels,” and “seeing.” Narratives typically include descriptive elements about the setting. Additionally, the concluding thought contrasts “inhaling” to “exhaling.” The reader can thus conclude that this paragraph has multiple patterns of organization that are intricately connected.

30 Examples of Topic Sentences (by grade level)

Yes! You are invited to use our tips for writing topic sentences as well as the examples of topic sentences listed below to help your students perfect their paragraph writing skills.

From the time young students begin to learn to write their own sentences, they start to understand that every paragraph has a structure.

As they progress throughout elementary school, into middle school, and go onto high school, they build upon the skills that they have learned, and they realize that the topic sentence sets the stage for all of their writing.

You see…

Writing a Good Topic Sentence

It doesn’t matter what type of writing your students are working on, they are going to need to know how to create strong, informative topic sentences that introduce the concept that will be discussed in their paragraph.

Elementary students begin to work on simple topic sentences as they work on their first paragraphs. Middle school students learn that their topic sentence must express the main idea of the paragraph.

High school students are often writing topic sentences that are complex and detailed and that allows them to expound upon an in-depth topic within the body of the paragraph. 

Purpose of a Topic Sentence

In addition to crafting strong topic sentences, students also need to realize that the first sentence of a paragraph must also be interesting and inviting.

They are literally pulling the reader in and encouraging them to learn more by reading the following sentence.

Every sentence that follows the topic sentence must support the overall theme and a well-developed and effective topic sentence will allow the paragraph to practically write itself. Further, writers will need to pay close attention to the content of a paragraph and to the transitions they use from the previous paragraph to the next.

Tips for Writing Topic Sentences

Initially, students may find it challenging to write a topic sentence in their own writing that captivates the attention of their reader.

Here are some tips and guidelines that can help them write their best topic sentences:

• Have your students start the process by writing down the topic that they want to discuss in their paragraph.
• Encourage them to write a simple sentence that introduces the main idea of their paragraph.
• Ask them to write down three ideas, examples, or arguments that support their topic sentence.
• Then, tell them to push their boundaries by rewriting the original topic sentence in order to grab the attention of the reader. 
• Finally, show them examples of topic sentences that they can use for inspiration.

Examples of Topic Sentences for Elementary School Students 

Elementary students often write simple topic sentences that focus solely on the main idea of the paragraph. Some examples of topic sentences for this age group include:

• When we had a snow day, I made snow angels, drank hot cocoa, and went sledding.
• Students should not have to do homework because it takes a lot of time.
• If you like going to the park, then you will love playing in the splash pad.
• Since I started first grade, I have learned about maps, explorers, and communities.

• My favorite ice cream flavor is banana chocolate chip because it is sweet and delicious.
• Goldfish make a great first pet for young children. 
• Riding my bicycle is my favorite after school activity.
• I believe that the most important classroom rule is to listen closely to the teacher.
• Science is the most interesting subject in school.

Middle School Examples of Topic Sentences

By middle school, students should begin to write more well-developed topic sentences that outline exactly what will be discussed in the following paragraph. Some examples of topic sentences for middle school students include:

• When playing basketball on a team, there are several rules that you will need to follow.
• Making an ice cream sundae is easy and fun, as long as you follow these simple steps. 
• If you want to avoid getting a cold, you should take some of these precautions.
• The three-toed sloth is a fascinating animal with many unique features. 

• When I went to the museum, I learned about the pharaohs of Ancient Egypt.
• The best rides at the amusement park are the rollercoasters that go upside down.  
• Although some people think tacos are the most delicious meal, I personally prefer to eat pasta.
• While there are differences between taking a beach vacation and a ski trip, there are some similarities as well.
• On my first day of middle school, I quickly realized that it was going to be very different from my elementary years.

Examples of Topic Sentences for High School Students

In high school, students have perfected the art of writing a complete topic sentence and they begin creating more complex and intricate sentences that they can use to anchor the entire paragraph. Some examples of topic sentences for high school students include: 

• When I sat down to dinner with my grandmother, I knew that I was going to learn so much more about her past. 
• College admissions officers should be considering more than grades; they should also be reviewing a student’s interests, job experience, and extra-curricular activities.
• Climate change is a complex issue that is being caused by a variety of factors. 
• As high school students, it is our responsibility to set a good example for younger children who look up to us.

• Learning a new language allows you to connect with people from another culture, to boost your reading and writing skills, and to improve your memory function.

• Academic Paragraphs: Examples of the MEAL Plan (video transcript)

The best way to understand the role of the topic sentence in paragraph development is to imagine that any given paragraph is a miniature essay that has its own thesis, support, and conclusion. The parts of a paragraph easily correspond to the parts of an essay:

Just as an effective essay starts off with an introduction that presents the paper's thesis statement and indicates the specific claim or argument that the essay will develop, each paragraph should begin with a topic sentence that indicates the focus of that paragraph, alerting the reader to the particular subtopic that the paragraph will provide evidence to support.

A strong topic sentence should be placed at or near the beginning of a paragraph. In addition, this sentence should focus on a specific issue, avoid the use of direct quotations, and leave room for support and analysis within the body of the paragraph. Read on to learn more about creating an effective topic sentence.

The topic sentence does not have to be the first sentence in the paragraph; however, it should come early in the paragraph in order to orient the reader to the paragraph's focus right away. Occasionally a writer may place a transition sentence before the topic sentence, to create continuity between topics.

Topic Sentence to begin paragraph:

In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

Transition Sentence + Topic Sentence to begin paragraph:

However, Morrison does not only use the emotional and spiritual bonds between her female characters to initiate their coming-of-age. In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness.

Specificity

Your topic sentence should be more narrowly focused than your thesis sentence, and you will want to make sure the claim you are making can be supported, argued, and analyzed within the body of your paragraph.

Example: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

In this topic sentence, the essayist is arguing that physical bonds of friendship, specifically, make the female characters more self-aware. Because this idea can be refuted or supported by readers (based on how successfully the essayist persuades his or her readers with examples and analysis from the novel), and because the claim is narrow enough to address within a single paragraph, the above sentence is a successful topic sentence.

Direct Quotations (Are Best Avoided)

Although it might be tempting to begin a paragraph with a compelling quotation, as a general rule, topic sentences should state the main idea of the paragraph in your own words. Direct quotations have a place later in the paragraph, where they may be incorporated to support the topic sentence.

Needs Improvement: As Morrison (1982) conveyed, the girls' "friendship let them use each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

Better: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness. Pointing to the connection of eyes meeting and bodies growing together, Morrison makes coming-of-age an interactive physical process between the adolescent protagonists. Specifically, Morrison describes how Sula and Nel have used "each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

In this second paragraph, the topic sentence appears first, immediately orienting readers to the main focus (or topic) of the paragraph. The quotation is used later in the paragraph as a form of evidence or support for the topic sentence.

If you are finding it challenging to create effective topic sentences, you might consider outlining before beginning to write a paper. The points and subpoints of an outline can then become the topic sentences for the paper's paragraphs.

Additionally, because the topic sentence functions similarly at the paragraph level to the thesis at the essay level, you may also find it helpful to check out our thesis statement construction information. Our resource on paragraphs has helpful information about the scope of a paragraph, as well.

Topic Sentence

Every paragraph should include a topic sentence that identifies the main idea of the paragraph. A topic sentence also states the point the writer wishes to make about that subject. Generally, the topic sentence appears at the beginning of the paragraph. It is often the paragraph’s very first sentence. A paragraph’s topic sentence must be general enough to express the paragraph’s overall subject. However, it should be specific enough that the reader can understand the paragraph’s main subject and point.

• The topic sentence should identify the main idea and point of the paragraph. To choose an appropriate topic sentence, read the paragraph and think about its main idea and point.
• The supporting details in the paragraph (the sentences other than the topic sentence) will develop or explain the topic sentence. Read all the supporting details in the paragraph and think about the ideas they discuss.
• The topic sentence should not be too general or too specific. When considering the options, look for a topic sentence that is general enough to show the paragraph’s main idea instead of just one of its details. The answer should be specific enough that the reader understands the main idea of the paragraph.

More About the Topic Sentence

A topic sentence is the most important sentence in a paragraph. Sometimes referred to as a focus sentence, the topic sentence helps organize the paragraph by summarizing the information in the paragraph. In academic writing, the topic sentence is usually the first sentence in a paragraph (although it does not have to be).

Purpose of the Topic Sentence

A topic sentence essentially tells readers about the rest of the paragraph. All sentences after it have to give more information about that sentence, prove it by offering facts about it, or describe it in more detail. For example, if the topic sentence concerns the types of endangered species that live in the ocean, then every sentence after that needs to expands on that subject.

Topic sentences also need to relate back to the thesis of the essay. The thesis statement is like a road map that will tell the reader or listener where you are going with this information or how you are treating it.

Topic Sentences and Controlling Ideas

Every topic sentence will have a topic and a controlling idea. The controlling idea shows the direction the paragraph will take.

Examples of a Topic Sentence

Topic Sentence: There are many reasons why pollution in ABC Town is the worst in the world.

The topic is "pollution in ABC Town is the worst in the world" and the controlling idea is "many reasons."

Topic Sentence: To be an effective CEO requires certain characteristics.

The topic is "To be an effective CEO" and the controlling idea is "certain characteristics."

Topic Sentence: There are many possible contributing factors to global warming.

The topic is "global warming" and the controlling idea is "contributing factors."

Topic Sentence: Fortune hunters encounter many difficulties when exploring a shipwreck.

The topic is "exploring a shipwreck" and the controlling idea is "many difficulties."

Topic Sentence: Dogs make wonderful pets because they help you to live longer.

The topic is "dogs make wonderful pets" and the controlling idea is "because they help you

to live longer."

Topic Sentence: Crime in poverty-stricken areas occurs because of a systemic discrimination.

The topic is "crime in poverty stricken areas" and the controlling idea is "systemic discrimination."

Topic Sentence: Teen pregnancy may be prevented by improved education.

The topic is "teen pregnancy may be prevented" and the controlling idea is "improved education."

Topic Sentence: Cooking requires a number of different skills.

The topic is "cooking" and the controlling idea is "many different skills."

Topic Sentence: It is important to be ready before buying a house.

The topic is "buying a house" and the controlling idea is “it is important to be ready."

Topic Sentence: Graduating from high school is important for many different reasons.

The topic is "graduating from high school" and the controlling idea is "many different reasons."

Topic Sentence: Having a first child is difficult because of the significant adjustments in your life.

The topic is "having a first child" and the controlling idea is "significant adjustments in your life."

Topic Sentence: Remodeling a kitchen successfully requires research and a good eye.

The topic is "remodeling a kitchen" and the controlling idea is "requires research and a good eye."

Topic Sentence Exercise

Write a topic sentence for the following paragraph. During the 1990s, I really enjoyed watching Friends on television every Thursday night. I really wanted Rachel’s haircut—I think every girl wanted Rachel’s haircut back then! Rachel’s haircut went really well with the Guess Jeans that were so popular in the 1990s. I remember all the advertisements for Guess and Calvin Klein Jeans that were in each month’s Sassy magazine. I do not think Sassy magazine exists anymore, but it was one of the most popular magazines for young women in the 1990s.

Topic Sentences Exercise Answer

The bold sentence is one possible topic sentence for the example paragraph.

Note: This is just one possible topic sentence—you may have thought of others that are also appropriate.

Thinking about the 1990s brings back fond memories for me about fashion and popular culture. During the 1990s, I really enjoyed watching Friends on television every Thursday night. I really wanted Rachel’s haircut—I think every girl wanted Rachel’s haircut back then! Rachel’s haircut went really well with the Guess Jeans that were so popular in the 1990s.

30 Topic Sentence Examples

June 24, 2024

What is an essay without a topic sentence? Well, confusion. In your writing, the topic sentence introduces what the paragraph will be about. It should cover the topic of the paragraph and the prime focus of what you want to discuss in the next several lines. And it can assist in smoothly transitioning into the next paragraph, the next point you’re about to make. Depending on the complexity of your argument, the topic sentence can also weave together several paragraphs. So when the topic sentence is missing, it’s easy to lose track of what your specific message is. Below, you find 30 topic sentence examples.

Think of the topic sentence as a tool in your writing kit. It’s there to help you signpost and structure the argument of your essay. Having it, while making sure the topic is interesting and clear, is essential to help your reader truly understand your thesis.

How do you write a topic sentence?

When you’re about to write an essay, you won’t find yourself immediately thinking of every topic sentence example at once. Figuring out what your thesis is going to be, the very purpose and argument of your essay, will be a necessary first step . Then you might want to create an outline . The outline can draft out what you want to cover in each paragraph or how your argument will be supported.

This is where the topic sentence comes in. For every paragraph, you can begin to think of topic sentence examples that best sum up the rest of your idea. The more interesting you can make the topic sentence, the better it will be, so long as you can support it. Remember, the topic sentence will introduce what you are going to discuss and expand on in the rest of the paragraph.

Examples (Continued)

Let’s take a look at these six topic sentence examples below that introduce a paragraph:

1) Studies over the last ten years have shown that the use of social media has a significant role in teenage mental health.

2) Kate Jackson and her family, who have all been San Francisco residents for 30 years, noted that this was the hottest summer yet.

3) Book sales across the country have actually increased this year, contrary to popular belief.

4) During COVID-19, people rushed to adopt pets, but after the pandemic ended many of those pets were surrendered to shelters.

5) It is undeniable what impact the meat industry has had on our environment.

6) In the 19th century in France, the creation of the Braille system was a significant turning point for those with disabilities.

How do you imagine the rest of the paragraph will turn out? How can you best support your topic sentence to strengthen your overall essay?

Support your paragraph with evidence

The topic sentence of your paragraph will not hold well if it is not backed up with the right evidence. After writing a topic sentence like the topic sentence examples above, the rest of your paragraph should include strong examples of evidence to support your argument. Doing so will only help validate your topic sentence and allow your reader to have more insight into your thesis.

Considering each topic sentence examples above, try to think of what types of evidence you would expect in that same paragraph. There could be reports on statistics, interviews, and other forms of evidence provided. How will yours be?

Where should the topic sentence go?

Now you know that your topic sentence should be followed by the right evidence. So it’s safe to assume that the topic sentence belongs at the very beginning of the paragraph.

Yet depending on the paragraph you’re working on, you can also place your “main” topic sentence after an “intro” topic sentence. Let’s take a look at the two examples below:

7) Due to rising temperatures around the world, people have had to flee their homes and relocate to areas less prone to fires or floods. (Intro topic sentence)

8) However, many have found that even these “safer” locations are still susceptible to eventual natural disasters. (Main topic sentence)

When we combine the two sentences, we get:

Due to rising temperatures around the world, people have had to flee their homes and relocate to areas less prone to fires or floods. However, many have found that even these “safer” locations are still susceptible to eventual natural disasters.

The first (intro) topic sentence example is more generic and introductory, functioning like a summary of an observation. The second (main) topic sentence example then presents another contradictory argument to that first point. Depending on the tone or argument you want to make in your paragraph, you can format your topic sentences in such a way to further sharpen your thesis. Whenever you have doubt though, you can always place one topic sentence at the beginning of the paragraph.

Sometimes less is more in writing the topic sentence

The topic sentence introduces the key concept of that paragraph, along with evidence and research findings. It can even be written as more than one sentence or perspective, as noted directly above. However, you also don’t want to say too much. Why?

You don’t want to give all of your information away at once. While it is imperative to write a clear, specific, and even complex topic sentence, it’s just as important to avoid being too general or too informative. Striking the right balance is going to help you structure the rest of your essay. After all, you have the rest of the paragraph and the rest of your essay to do that, which leads us to our next point.

Topic sentences for smoother transitions

Like a game of dominoes, your paragraphs are all connected and should flow smoothly into the next statement you are making. As you are building your outline, or even as you’re already writing, consider how your previous paragraph transitions into the next . This depends on the intention of each paragraph and how you are structuring your argument.

Topic sentences for paragraph transitions have many functions. They will elaborate on more examples. They can wrap up or summarize a preceding point you made, providing another perspective. Also, they can go against a fact or opinion you wrote, which is a great way to strengthen your overall thesis and they can also be posed as a question.

Take a look at these transitional topic sentence examples below:

9) In fact, walking as a form of exercise has shown to reduce cortisol levels.

10) Furthermore, city council representatives have said that environmental sustainability has remained at the top of the agenda, but activists have largely disagreed.

11) While the strike in Hollywood has come to an end, many writers are still without employment and searching for new ways to restart their careers.

12) However, grocery prices across the country still seem to have risen.

13) Despite the state’s discontinued funding for the arts, is there another feasible way for these students to gather together and flourish as young artists at their school?

More than one paragraph: Topic sentences that expand into several key points

So far we’ve covered topic sentences that elaborate on just one paragraph. However, you might find that one topic sentence (or two) can best address several paragraphs. This usually occurs when you’re trying to introduce a bigger argument to serve your essay.

Let’s take one of the single paragraph topic sentences from earlier above and expand it by adding a connecting topic sentence to it:

14)Book sales across the country have actually increased this year, contrary to popular belief.

15) A report from the Association of American Publishers’ StatShot program states that in April sales over a year there has been an 18% increase.

These two topic sentence examples can even serve as their own introductory paragraph. This can then lead into more paragraphs related to the topic of specific book sales increasing across the country:

Book sales across the country have actually increased this year, contrary to popular belief. A report from the Association of American Publishers’ StatShot program states that in April sales over a year there has been an 18% increase.

Make the topic sentence interesting, not obvious

Check out 15 more topic sentence examples below. How do they introduce the topic, and what does it make you want to learn more about? You can imagine what kind of paragraph, or paragraphs, might follow afterwards:

16) When brewed correctly, coffee can hold strong, subtle hints of flavors such as chocolate or fruit, depending on the level of acidity.

17) Although today life in 1920s Paris is often romanticized for its glamor, jazz, and fashion, the city was still struggling to recover from the devastation of World War I.

18) Strict social rules dominated the Victorian Era, despite Britain’s expansion around the world in pursuit of wealth and power.

19) Dogs have a keen sense of time, so much so that they can predict when you’re late to take them out for a walk.

20) Before winter arrives, birds such as cranes and waterfowl follow preferred aerial pathways during their yearly migrations.

21) Conservation methods have helped local farms in their efforts to prioritize sustainability.

22) Did you know that humans would have a better chance of reaching Mars if they had a base set up on the moon?

23) The Pacific Ocean covers more than 30 percent of the earth’s surface, and it is home to so many life forms that have not yet been studied.

24) It is often debated whether or not student athletes should be paid for their performance, considering the cost for them to succeed.

25) Becoming a successful CEO doesn’t just happen overnight.

26) Although purchasing a home is considered a great form of investment, potential buyers should look at the real estate market first.

27) Watching my mother work three jobs to support our family has taught me the importance of resilience and strong work ethic.

28) Historical fiction not only has the power to teach us of actual past events. It also allows us to step into the lives of those we would have never met.

29) Parents and teachers at Sunnyroad School District are advocating for schools to provide free computers for their students – but the administrators aren’t so sure.

30) Across the country, the debate around whether teenagers should be allowed to use smart phones on campus has been circulating.

The topic sentence as a guide

One way to look at topic sentences is to imagine them as guiding compasses of your essay. Whatever point you are trying to make, the topic sentence has the power to guide your reader down a certain path. Choose wisely!

• B.A., English, State University of New York

A topic sentence is a  sentence , sometimes at the beginning of a paragraph , that states or suggests the main idea (or topic ) of a paragraph.

Not all paragraphs begin with topic sentences. In some, the topic sentence appears in the middle or at the end. In others, the topic sentence is implied or absent altogether.

Examples and Observations

• " Salva and the other boys made cows out of clay. The more cows you made, the richer you were. But they had to be fine, healthy animals. It took time to make a lump of clay look like a good cow. The boys would challenge each other to see who could make the most and best cows." (Linda Sue Park, A Long Walk to Water . Clarion, 2010)
• " Momma bought two bolts of cloth each year for winter and summer clothes. She made my school dresses, underslips, bloomers, handkerchiefs, Bailey's shirts, shorts, her aprons, house dresses and waists from the rolls shipped to Stamps by Sears and Roebuck. . . ." (Maya Angelou, I Know Why the Caged Bird Sings . Random House, 1969)
• " You discover what it is like to be hungry. With bread and margarine in your belly, you go out and look into the shop windows. Everywhere there is food insulting you in huge, wasteful piles; whole dead pigs, baskets of hot loaves, great yellow blocks of butter, strings of sausages, mountains of potatoes, vast Gruyère cheeses like grindstones. A snivelling self-pity comes over you at the sight of so much food. You plan to grab a loaf and run, swallowing it before they catch you; and you refrain, from pure funk." (George Orwell, Down and Out in Paris and London . Victor Gollancz, 1933)
• " The flavor that salt imparts to food is just one of the attributes that manufacturers rely on. For them, salt is nothing less than a miracle worker in processed foods. It makes sugar taste sweeter. It adds crunch to crackers and frozen waffles. It delays spoilage so that the products can sit longer on the shelf. And, just as importantly, it masks the otherwise bitter or dull taste that hounds so many processed foods before salt is added." (Michael Moss, Salt, Sugar, Fat: How the Food Giants Hooked Us . Random House, 2013)
• " The very idea of retirement is a relatively new invention. For most of human history, people worked until they died or were too infirm to lift a finger (at which point they died pretty fast anyway). It was the German statesman Otto von Bismarck who first floated the concept, in 1883, when he proposed that his unemployed countrymen over the age of 65 be given a pension. This move was designed to fend off Marxist agitation—and to do so on the cheap, since few Germans survived to that ripe old age." (Jessica Bruder, "The End of Retirement." Harper's , August 2014)
• " Grandma's room I regarded as a dark den of primitive rites and practices. On Friday evenings whoever was home gathered at her door while she lit her Sabbath candles. . . ."  (E.L. Doctorow, World's Fair . Random House, 1985)
• " Genealogy is an ancient human preoccupation. The God of Hebrew Scripture promised Abraham descendants beyond number, like the stars in the sky and the sand on the seashore. The apostles Matthew and Luke claim that Abraham's lineage went on to include King David and eventually Jesus, though the specifics of their accounts are contradictory. Muslims trace Mohammed's line back through Abraham, to Adam and Eve." (Maud Newton, "America's Ancestry Craze." Harper's , June 2014)
• " O nce, in a restaurant in Italy with my family, I occasioned enormous merriment, as a nineteenth-century humorist would have put it, by confusing two Italian words. I thought I had, very suavely, ordered for dessert fragoline —those lovely little wild strawberries. Instead, I seem to have asked for fagiolini —green beans. The waiter ceremoniously brought me a plate of green beans with my coffee, along with the flan and the gelato for the kids. The significant insight the mistake provided—arriving mere microseconds after the laughter of those kids, who for some reason still bring up the occasion, often—was about the arbitrary nature of language: the single 'r' rolled right makes one a master of the trattoria, an 'r' unrolled the family fool. . . ." (Adam Gopnik, "Word Magic." The New Yorker , May 26, 2014)
• " In seventeenth-century Europe, the transformation of man into soldier took on a new form, more concerted and disciplined, and far less pleasant, than wine. New recruits and even seasoned veterans were endlessly drilled, hour after hour, until each man began to feel himself part of a single, giant fighting machine. . . ." (Barbara Ehrenreich, Blood Rites: Origins and History of the Passions of War . Henry Holt and Company, 1997)
• " What is the appeal of train travel? Ask almost any foamer, and he or she will invariably answer, 'The romance of it!' But just what this means, they cannot really say. It's tempting to think that we are simply equating romance with pleasure, with the superior comfort of a train, especially seated up high in the observation cars. . . ." (Kevin Baker, "21st Century Limited: The Lost Glory of America's Railroads." Harper's , July 2014)
• " Because science fiction spans the spectrum from the plausible to the fanciful, its relationship with science has been both nurturing and contentious. For every author who meticulously examines the latest developments in physics or computing, there are other authors who invent 'impossible' technology to serve as a plot device (like Le Guin’s faster-than-light communicator, the ansible) or to enable social commentary, the way H. G. Wells uses his time machine to take the reader to the far future to witness the calamitous destiny of the human race." (Eileen Gunn, "Brave New Words." Smithsonian , May 2014)
• " I passed all the other courses that I took at my university, but I could never pass botany. . . ." (James Thurber, My Life and Hard Times . Harper & Row, 1933)
• " What is there about this wonderful woman? From next door, she comes striding, down the lawn, beneath the clothesline, laden with cookies she has just baked, or with baby togs she no longer needs, and one's heart goes out. Pops out. The clothesline, the rusted swing set, the limbs of the dying elm, the lilacs past bloom are lit up like rods of neon by her casual washday energy and cheer, a cheer one has done nothing to infuse." (John Updike, "One's Neighbor's Wife." Hugging the Shore: Essays and Criticism . Knopf, 1983)
• " Television. Why do I watch it? The parade of politicians every evening: I have only to see the heavy, blank faces so familiar since childhood to feel gloom and nausea. . . ." (J.M. Coetzee, Age of Iron . Random House, 1990)
• " Anyone who has made the coast-to-coast journey across America, whether by train or by car, has probably passed through Garden City, but it is reasonable to assume that few travelers remember the event. It seems just another fair-sized town in the middle--almost the exact middle--of the continental United States. . . ." (Truman Capote, In Cold Blood . Random House, 1966)
• " Rodeo, like baseball, is an American sport and has been around almost as long. . . ." (Gretel Ehrlich, The Solace of Open Spaces . Viking Penguin, 1985)
• " What a piece of work is a book! I am not talking about writing or printing. I am talking about the codex we may leaf through, that may be put away on a shelf for whole centuries and will remain there, unchanged and handy. . . ." (William Golding, A Moving Target . Farrar, Straus and Giroux, 1982)

Characteristics of an Effective Topic Sentence

• "A good topic sentence is concise and emphatic . It is no longer than the idea requires, and it stresses the important word or phrase. Here, for instance, is the topic sentence which opens a paragraph about the collapse of the stock market in 1929: "The Bull Market was dead."(Frederick Lewis Allen) Notice several things. (1) Allen's sentence is brief . Not all topics can be explained in six words, but whether they take six or sixty, they should be phrased in no more words than are absolutely necessary. (2) The sentence is clear and strong: you understand exactly what Allen means. (3) It places the keyword—'dead'—at the end, where it gets heavy stress and leads naturally into what will follow. . . . (4) The sentence stands first in the paragraph. This is where topic sentences generally belong: at or near the beginning." (Thomas S. Kane, The New Oxford Guide to Writing . Oxford Univ. Press, 1988)

Positioning a Topic Sentence

"If you want readers to see your point immediately, open with the topic sentence . This strategy can be particularly useful in letters of application or in argumentative writing. . . . "When specific details lead up to a generalization, putting the topic sentence at the end of the paragraph makes sense. . . . "Occasionally a paragraph's main idea is so obvious that it does not need to be stated explicitly in a topic sentence." (Andrea Lunsford, The St. Martin's Handbook . Bedford/St. Martin's, 2008)

Guidelines for Composing Topic Sentences

"The topic sentence is the most important sentence in your paragraph. Carefully worded and restricted, it helps you generate and control your information. An effective topic sentence also helps readers grasp your main idea quickly. As you draft your paragraphs, pay close attention to the following three guidelines:

• Make sure you provide a topic sentence. . . .
• Put your topic sentence first.
• Be sure your topic sentence is focused. If restricted, a topic sentence discusses only one central idea. A broad or unrestricted topic sentence leads to a shaky, incomplete paragraph for two reasons:
• The paragraph will not contain enough information to support the topic sentence .
• A broad topic sentence will not summarize or forecast specific information in the paragraph."

(Philip C. Kolin, Successful Writing at Work , 9th ed. Wadsworth, 2010)

Testing for Topic Sentences

"When testing your article for topic sentences , you should be able to look at each paragraph and say what the topic sentence is. Having said it, look at all the other sentences in the paragraph and test them to make sure they support it. . . .

"If you find that you have come up with the same topic sentence more than once, you have two paragraphs doing the same work. Cut one of them out.

"If you find a paragraph that has several sentences that don't support the topic sentence, see if all the outlaw sentences support some other topic sentence and turn the one paragraph into two." (Gary Provost, "How to Test Your Articles for the 8 Essentials of Nonfiction." Handbook of Magazine Article Writing , ed. by Jean M. Fredette. Writer's Digest Books, 1988)

Frequency of Topic Sentences

"Teachers and textbook writers should exercise caution in making statements about the frequency with which contemporary professional writers use simple or even explicit topic sentences in expository paragraphs. It is abundantly clear that students should not be told that professional writers usually begin their paragraphs with topic sentences."  (Richard Braddock, "The Frequency and Placement of Topic Sentences in Expository Prose." Research in the Teaching of English . Winter 1974)

How to Write a Good Topic Sentence

Last Updated: June 26, 2024 Fact Checked

She earned her PhD in English from the University of Georgia in 2015. There are 10 references cited in this article, which can be found at the bottom of the page.

Perfecting the skill of writing topic sentences is essential to successful writing. A topic sentence usually comes at the beginning of a paragraph and lets your reader know what to expect from each paragraph. Think of it as the preview for a movie or a headline in a newspaper, highlighting the “main point” that’s to come in that paragraph. [1] X Research source Make sure your topic sentences are up to par, and the rest of your writing will feel like a breeze.

Writing a Successful Topic Sentence

• Keep in mind that this is not an invitation to simply announce your topic. “Today I’m going to discuss the benefits of gardening” is not an effective topic sentence. You should be able to make your intentions clear without stating them explicitly.
• The topic sentence in this example states a clear direction (“health benefits of gardening”) that you can then elaborate on in your paragraph.

• Don’t write too vague or general an idea or you will never be able to discuss it in a single paragraph. This is too general: “The United States suffered a lot during the Civil War.”
• Don’t write too narrow of a statement. There’s nothing much to talk about then, because it’s probably a fact. This is too narrow: “Christmas trees are either cedars or firs."
• Instead, aim for a good balance: “Sherman’s destruction in the South during the Civil War also caused incredible suffering.” This is big enough to relate to the broader idea of an essay, but not so narrow that there’s nothing left to discuss.

• Describe a character. This can be a physical or emotional description.
• Use dialogue. If there is a relevant conversation that will attract your reader’s attention, consider using part of it to start your paragraph.
• Portray an emotion. Use the opening sentence to portray an emotion to your reader.
• Use detail. While you don’t want to write a run on sentence by creating too much detail, it’s a good idea to create interest using sensory language in your topic sentence.
• Avoid rhetorical questions. While you want your reader to formulate questions in his or her mind, you do not want to formulate the questions yourself.

• Avoid presenting only facts in your topic sentence. While facts may be interesting, they do not introduce the reader to your paragraph nor do they draw the reader in. If you wish to include a fact, also include your own input. For example, instead of writing “All dogs need food,” try “All dogs need regular care, including healthy food, and children are the best ones to do it.” Alternatively, save your facts to use as evidence in the body of your paragraph.

• Using transitional elements, such as “In addition” or “In contrast,” is a good way to show the relationship between your ideas.
• For example: “Although gardening has many health benefits, people still need to exercise caution when outside.” This topic sentence establishes a connection to the main idea of the previous paragraph (“health benefits of gardening”) and points to the direction of the new paragraph (“things to be cautious of”).

Planning Your Topic Sentences

• You don’t have to write a formal outline using Roman numerals and the like. Even a loose, idea-based outline can help you know what you want to discuss.

• A topic sentence, unlike a thesis statement, doesn’t have to present an argument. It can present a “preview” of what the paragraph will argue or discuss.

• For example, a topic sentence could look like this: “In addition, increasing funding for public roads in Jackson County will improve local residents’ quality of life.” The rest of the sentences in this paragraph would relate to the main idea of public roads and how they will help benefit local residents.
• This is not as successful a topic sentence: “Increased funding for public roads in Jackson County has decreased traffic by 20%.” While this is probably an interesting fact for your argument, it’s too narrow for a topic sentence. The topic sentence has to direct the whole paragraph.

Avoiding Common Problems

• Unless it is an opinion piece, avoid using ‘I’ in your topic sentences.

• Rather than stating something like “In the story, Amelia did many good things such as help out her friends, talk to her parents, and support her team at school” say something like “As a result of the many activities Amelia participated in, she was recognized for her positive influence on the community.”

Sample Topic Sentences

• Avoid using words like you or we because it implies you know the reader, which you don’t. Thanks Helpful 0 Not Helpful 0
• In formal writing, avoid contractions such as “don’t,” “can’t,” and “isn’t.” Also avoid other common contractions like “would’ve” and “could’ve” which are commonly used. Instead type them out to look like “do not,” “can not”, “is not”, “would have”, and “could have.” Thanks Helpful 0 Not Helpful 0

Thesis vs. Topic Sentence: What’s the Difference and Why It Matters

Understanding the difference between a thesis statement and a topic sentence is essential for effective writing. Both play vital roles in structuring an academic paper, but they serve distinct purposes. A thesis statement presents the main argument of the paper, while topic sentences introduce the main idea of each paragraph. Knowing how to use both correctly can greatly enhance the clarity and focus of your writing.

Key Takeaways

• A thesis statement summarizes the main argument of the paper, while a topic sentence introduces the main idea of each paragraph.
• Thesis statements guide the overall direction of the paper, while topic sentences help organize individual paragraphs.
• A strong thesis statement is clear, specific, and debatable, while a good topic sentence should relate directly to the thesis.
• Both thesis statements and topic sentences should be revised for clarity and focus as the writing process progresses.
• Understanding the roles of thesis statements and topic sentences can improve reader engagement and comprehension.

Distinguishing Between Thesis Statements and Topic Sentences

Clarifying Definitions

A thesis statement and a topic sentence serve different purposes in writing. A thesis statement presents the main argument of your paper , while a topic sentence introduces the main idea of a specific paragraph. Understanding this distinction is crucial for effective writing.

Understanding Their Roles

The thesis statement acts as a roadmap for your entire paper, guiding the reader through your argument. In contrast, topic sentences help to organize individual paragraphs, ensuring that each one relates back to the thesis. This structure helps maintain clarity and focus throughout your writing.

Common Misconceptions

Many students confuse thesis statements with topic sentences. A common misconception is that a topic sentence can serve as a thesis statement. However, a thesis statement is different from a topic statement ; it articulates a specific argument rather than merely stating what the paper is about. This misunderstanding can lead to vague writing and unclear arguments.

The Importance of a Thesis Statement

Establishing direction.

A thesis statement is essential because it provides a clear direction for your paper. It tells the reader what to expect and helps you stay focused on your main argument. Without it, your writing may wander off-topic, making it hard for readers to follow your ideas.

Guiding the Reader

Your thesis statement acts as a roadmap for the reader. It highlights the main points you will discuss, ensuring that they understand the purpose of your paper. This clarity is crucial for keeping your audience engaged and informed.

Enhancing Coherence

A strong thesis statement helps in organizing your thoughts and arguments. It ensures that all parts of your paper connect back to the main idea, creating a cohesive piece of writing. This coherence is vital for effective communication, especially in academic settings where clarity is key.

In summary, a well-crafted thesis statement is not just a formality; it is the backbone of your writing. It helps you articulate your ideas clearly and keeps your readers engaged. As you work on your thesis, consider resources like research rebels® for tips on crafting effective statements. They provide valuable insights that can make your thesis writing process smoother and more enjoyable.

Characteristics of a Strong Thesis Statement

Specificity and clarity.

A strong thesis statement must be specific and clear. It should directly state your main argument without any ambiguity. For example, instead of saying "Many people think that social media is bad," you could say, "Social media platforms, by promoting unrealistic standards , contribute to increasing anxiety among teenagers." This version is more focused and sets a clear direction for your paper.

Debatable Claims

Your thesis should present a claim that can be debated. This means it should not be a simple fact but rather an assertion that others might disagree with. For instance, saying "Climate change is real" is a fact, but saying "Government policies should prioritize renewable energy to combat climate change" invites discussion and debate.

Supporting Evidence

A strong thesis statement is backed by evidence. This means you should be prepared to support your claim with facts, statistics, or examples. For instance, if your thesis is about the impact of technology on education, you might include studies that show how technology improves learning outcomes.

The Role of Topic Sentences in Academic Writing

Defining topic sentences.

A topic sentence is a crucial element in academic writing. It introduces the main idea of a paragraph, setting the tone and direction for the sentences that follow. This sentence acts as a guide for both the writer and the reader, ensuring clarity and focus.

Connecting Ideas

Topic sentences help in connecting ideas across paragraphs. By clearly stating the main point, they allow readers to follow the flow of the argument. This connection is essential for maintaining coherence in your writing.

Structuring Arguments

When you structure your arguments, topic sentences play a vital role. They not only summarize the main point of the paragraph but also relate it back to the thesis statement. This relationship reinforces the overall argument of your paper, making it more persuasive.

In summary, effective topic sentences are essential for clear and organized writing. They help in defining the main idea, connecting thoughts, and structuring arguments, ultimately guiding the reader through your work.

How Thesis Statements and Topic Sentences Interact

Creating a cohesive argument.

To create a strong argument in your writing, both thesis statements and topic sentences play crucial roles. Your thesis statement serves as the main idea of your entire paper , while topic sentences introduce the main idea of each paragraph. This relationship helps to ensure that every part of your essay supports your overall argument.

Transitioning Between Ideas

When you write, it's important to connect your ideas smoothly. Topic sentences can act as bridges between paragraphs, guiding the reader from one point to the next. For example, if your thesis statement discusses the impact of climate change, a topic sentence in the next paragraph might introduce a specific effect, like rising sea levels. This creates a logical flow in your writing.

Supporting the Thesis

Each topic sentence should relate back to your thesis statement. This means that as you develop your paragraphs, you should always ask yourself how each point supports your main argument. This connection not only strengthens your writing but also helps your reader follow your reasoning.

In summary, understanding how thesis statements and topic sentences interact is essential for crafting a well-structured essay. By ensuring that each topic sentence aligns with your thesis, you create a clear and compelling argument that engages your reader.

Common Errors in Thesis and Topic Sentence Construction

Vagueness and ambiguity.

One of the most common mistakes in writing thesis statements and topic sentences is vagueness . When your sentences lack specific details, they can confuse the reader. For example, instead of saying, "Many people think that dogs are great pets," you could say, "Many families prefer small dog breeds, like Chihuahuas and Pomeranians , for their friendly nature and low maintenance ." This change makes your point clearer and more engaging.

Overgeneralization

Another frequent error is overgeneralization. This happens when you make broad claims that are hard to support. For instance, saying, "All dogs are friendly" is too sweeping. Instead, you might say, "While many dogs are friendly, certain breeds, like Chihuahuas , can be more reserved around strangers." This approach allows for a more nuanced discussion.

Lack of Focus

A lack of focus can also weaken your writing. If your thesis or topic sentence tries to cover too much, it can lose its impact. For example, instead of writing, "This paper will discuss dogs, cats, and birds," you should narrow it down to something like, "This paper will focus on the benefits of owning dogs as pets ." This specificity helps guide your writing and keeps your audience engaged.

By avoiding these common errors, you can create stronger thesis statements and topic sentences that effectively communicate your ideas and engage your readers.

Examples of Effective Thesis Statements

Analyzing strong examples.

When crafting a thesis statement, it’s essential to ensure that it is clear and concise. Here are some examples of effective thesis statements:

• "The rise of social media has significantly altered the way we communicate, leading to both positive and negative effects on interpersonal relationships."
• "Climate change is the most pressing issue of our time, requiring immediate action from governments and individuals alike to mitigate its effects."
• "The portrayal of women in media often reinforces harmful stereotypes, which can have detrimental effects on societal perceptions of gender roles."

Comparing Weak Statements

Weak thesis statements often lack clarity or specificity. Here are examples of ineffective thesis statements:

• "Social media is bad."
• "Many people think climate change is real."
• "Media affects people."

Learning from Real-World Applications

In real-world scenarios, effective thesis statements can be found in various forms of writing, from academic papers to opinion pieces. For instance, in the article " Mastering Business Statistics with 'Statistics for Managers Using Microsoft Excel'", the thesis emphasizes the importance of statistical literacy in business decision-making. This clear focus helps guide the reader through the complexities of the subject.

By understanding how to write a thesis fast and easily, you can enhance your writing skills and create compelling arguments that engage your audience.

Crafting Effective Topic Sentences

Strategies for clarity.

When you write a topic sentence, make sure it clearly states the main idea of the paragraph. This helps your readers understand what to expect. A good topic sentence should be specific enough to guide the reader but general enough to allow for discussion. For example:

• "The meat industry significantly impacts the environment." This sentence sets the stage for further exploration of the topic.

Maintaining Focus

To keep your writing on track, ensure that each topic sentence relates directly to your thesis statement. This connection helps maintain a clear focus throughout your paper. You can ask yourself:

• Does this topic sentence support my main argument?
• Is it relevant to the paragraph's content? By answering these questions, you can refine your topic sentences to better align with your overall message.

Using Transitions

Transitions are essential for smooth reading. When moving from one paragraph to another, consider using transition words in your topic sentences. For instance:

• "In addition to environmental concerns, the meat industry also raises ethical issues." This not only connects the ideas but also prepares the reader for new information.

By following these strategies, you can craft effective topic sentences that enhance the clarity and flow of your writing. Remember, a well-structured paragraph begins with a strong topic sentence that guides the reader through your argument.

The Impact of Thesis and Topic Sentences on Reader Engagement

Capturing interest.

A strong thesis statement and clear topic sentences are essential for grabbing your reader's attention. When you present a compelling argument right from the start, you invite your audience to engage with your work. This initial hook is crucial in academic writing, as it sets the tone for the entire paper.

Maintaining Attention

Once you have captured your reader's interest, it’s important to keep them engaged. Well-crafted topic sentences act as signposts, guiding readers through your arguments. They help maintain focus by clearly stating what each paragraph will discuss. This clarity allows readers to follow your line of thought without getting lost.

Encouraging Critical Thinking

A well-defined thesis statement encourages readers to think critically about your argument. It invites them to consider your perspective and the evidence you present. By clearly stating your main point, you challenge your audience to engage with your ideas and form their own opinions. This interaction is vital for fostering a deeper understanding of the topic.

In summary, both thesis statements and topic sentences play a significant role in engaging readers. They not only capture interest but also maintain attention and encourage critical thinking. By focusing on these elements, you can enhance the overall effectiveness of your writing.

Revising Thesis and Topic Sentences

Importance of Revision

Revising your thesis and topic sentences is crucial for creating a strong academic paper. A well-crafted thesis statement serves as the backbone of your essay , guiding your arguments and ensuring clarity. As you write, revisit your thesis to ensure it reflects your evolving ideas and insights. This process helps maintain focus and coherence throughout your work.

Techniques for Improvement

To effectively revise your thesis and topic sentences, consider the following steps:

• Review your thesis statement : Ensure it clearly states your main argument and is specific enough to guide your writing.
• Align topic sentences with your thesis : Each topic sentence should connect back to your thesis, summarizing the main point of the paragraph.
• Seek feedback : Share your work with peers or instructors to gain fresh perspectives and suggestions for improvement.

Feedback and Collaboration

Engaging in discussions about your thesis and topic sentences can lead to valuable insights. Collaborating with others allows you to refine your ideas and strengthen your arguments. Remember, revising is not just about correcting mistakes; it’s about enhancing the overall quality of your writing. By focusing on these aspects, you can create a more compelling and coherent academic paper that effectively communicates your ideas.

In summary, revising your thesis and topic sentences is an essential part of the writing process. By following these steps and seeking feedback, you can ensure that your writing remains focused and impactful. This will ultimately lead to a more engaging and persuasive essay.

The Evolution of Thesis Statements in Academic Writing

Historical perspectives.

The concept of a thesis statement has evolved significantly over time. Originally, the term "thesis" comes from the Greek word thésis , which Aristotle discussed in his works. In the past, thesis statements were often vague and lacked the clarity needed for effective academic writing. Today, a strong thesis statement is essential for guiding readers through complex arguments.

Current Trends

In modern academic writing, thesis statements have become more focused and specific. They serve as a roadmap for the reader, outlining the main argument and direction of the paper. This shift reflects a broader trend towards clarity and precision in academic discourse. For instance, many educators now emphasize the importance of crafting a thesis that is not only clear but also debatable, allowing for meaningful discussion.

Future Directions

Looking ahead, the role of thesis statements is likely to continue evolving. As academic writing becomes more interdisciplinary, the expectations for thesis statements may shift. Writers will need to adapt their thesis statements to address diverse audiences and incorporate various perspectives. This adaptability will be crucial for maintaining relevance in an ever-changing academic landscape.

In summary, understanding the evolution of thesis statements helps you appreciate their importance in academic writing. As you learn how to write dissertation fast , remember that a well-crafted thesis statement is your first step toward effective communication in your research.

Creating a Successful Research Topic Statement (PSY)

In this tutorial, we will identify what makes for a successful research topic.

Most research topics start out as a general and often vague idea that a researcher has an interest in investigating.

Inexperienced researchers, including most doctoral learners, frequently think of topics that are quite interesting, but not narrowly enough focused for a dissertation.

This tutorial will guide you through a set of steps designed to help you come up with a topic, first of all, and secondly to focus it more tightly so that you can begin a meaningful and successful search of the existing literature to discover whether your topic is actually researchable.

This tutorial's primary objective is to prepare you to create a successful research topic that may become the topic of your dissertation. To do that, we'll work through the following issues:

• First, what are the characteristics of a well-formed research topic?
• Second, how are research topics evaluated?
• Third, how can the key concepts and the population be narrowed and focused so that they are researchable?
• Fourth, how can the relationship among concepts be named so that the appropriate methodological literature can be accessed in the literature review?

Obviously, in Track 1 you are at the beginning of your studies toward the doctorate, and perhaps your dissertation is far from your thoughts. We are starting the process now, however, because our experience has been that when learners wait to start searching for their topics, it often creates a serious problem for them when they actually start the dissertation. That problem can take many forms, but the most common one is that they have not had sufficient time (and training) in exhaustively searching the relevant literature to discover whether the topic they are interested in is even viable—and without a good topic statement, a good literature search is impossible. So let's begin.

What Is a Research Topic?

A research topic is an area of interest to a researcher that is first of all, researchable. It is focused narrowly enough that its key concepts are quite plain and well integrated. It is a topic or subject that can be found in the existing literature of the researcher's field, which shows that it is of some interest or importance to that field, and has some important characteristics.

Characteristics of a Well-formed Research Topic

The first mark of a well-formed topic is that it clearly states the key concepts to be investigated. Sometimes, only one concept is named—those studies often turn out to be qualitative, but not always. More often, two or more key concepts are named. Next, it identifies the relationship or relationships among those concepts that the researcher intends to explore. Obviously, if only one concept was named, there won't be a relationship, but in that case a word like "describes" or "experiences" will give a clue to the kind of information desired. Third, a research topic specifies the population of interest to be investigated. Finally, a research topic is just a phrase. That is, it is not a full sentence with a verb. However, the well-formed topic statement will embed the actual topic in a complete sentence. Let's look at some examples.

Some Examples of Topic Statements

Here are a few topic statements that eventually lead to successful dissertations:

• Elementary age students' needs for family-based counseling services.
• Indigenous people's responses to encounters with law enforcement.
• Impact of mother's death on daughters in poor, middle class, and wealthy families.
• The relationship between assignment strategies to prevent burnout used by managers of first responders and the occurrence of burnout.
• Employees' productivity as a function of their managers' management styles.
• Strategies used by mainstream classroom teachers to manage children with behavior problems who do not receive special education.

You can see immediately that all six examples, taken from the four schools in Capella University, are phrases, not complete sentences. So far, so good. The first mark of a successful topic statement is that it identifies the key concepts to be investigated, right? Let's see how the examples do that.

Evaluating the Form of the Examples: Key Concepts

In the first example, we seem to have two key concepts: "needs" and "family-based counseling services." Are they stated clearly? Probably not clearly enough: what is meant by "needs" and "family-based counseling services" is not immediately transparent. This topic will need some work, but most topics start out this way.

Let's try another: Indigenous people’s responses to encounters with law enforcement. Here, there seem to be two key concepts: "responses" and "encounters with law enforcement." These concepts are quite broad and will have to be narrowed considerably to support a researchable topic, but they provide a good start.

Let's do one more: Employees' productivity as a function of their managers' management styles.

Here, there are two key concepts, right? Productivity and management styles.

Evaluating the Form of Topics: Relationship(s) among the Key Concepts

The second mark of a successful topic is that it identifies any relationship to be investigated between or among the key concepts. Let's look at the third example to see about this.

This topic meets our criterion of being a phrase. It seems to state at least two concepts (but with multiple levels): "death" and "socio-economic status of daughters." What about the relationship? Well, it is captured in that word "impact."

An "impact" in research jargon means the effect that one concept—death—has on another concept, in this case, the daughters. One can, in fact, replace the word impact with the word effect without changing the meaning at all. So the topic is proposing a cause-and-effect kind of relationship.

Let's look at another example: The relationship between assignment strategies to prevent burnout used by managers of first responders and the occurrence of burnout

This seems complicated, but it really isn't. First, let's check the key concepts: "Assignment strategies to prevent burnout" would seem to be one key concept, and "occurrence of burnout" would be the other. These are reasonably clear, or probably would be to someone in the human resources or management worlds. No doubt they will be further clarified as the researcher works on the topic's wording. But what about the relationship? It is in the word "relationship," obviously. And in research jargon, a "relationship" between A and B is a particular kind of relationship, called a correlation.

Now, play with the other topics to see if you can identify the relationship—if any.

Evaluating the Form of Topics: Target Population

The third sign of a successful topic is that it names the target population, the group of people or organizations or groups that the researcher is interested in. Let's evaluate some of our examples on this point.

• Elementary age students' needs for family-based counseling services : The population here is stated: Students of elementary school age.
• Indigenous people's responses to encounters with law enforcement: Here as well, the population is indigenous people.
• Impact of mother's death on daughters in poor, middle class, and wealthy families: The population is daughters in three socio-economic groups.
• The relationship between assignment strategies to prevent burnout used by managers of first responders and the occurrence of burnout: You determine who the population is in this one.

Is It Managers or Is It First Responders?

The population is managers of first responders. Or is it? The awkward wording of the topic makes this a bit hard to digest. The burnout occurs in the first responders, so maybe they are the population. But the first responders' managers are the ones using the management strategies, so are they the population?

Well, the two key concepts are management strategies (used by managers) and rate of burnout (in first responders), so the researcher will have to get information from both groups of people, so both are the target population: first responders and their managers.

Take a minute and try to figure out the rest of our examples.

Summing Up the Characteristics of a Successful Topic

We've seen in action the three chief marks of a successful research topic.

• The topic states the key concepts to be investigated.
• It states what relationship between or among the concepts will be explored. Remember, if there is only one concept (which often is the case in qualitative studies), there won't be a relationship. But if there are two or more key concepts, look for the relationship between or among them.
• The successful topic names the population of interest for the study.

A well-formed research topic will have these characteristics, but simply having them is not sufficient. The elements also need to be well-focused and narrowed down to a point where the research becomes feasible. Let's take a look at a simple method for doing this.

Narrowing the Focus

Take a look at this grid. You'll see that one of our topics has been broken out into the first column. The population is first—indigenous people—followed by two concepts: responses and law enforcement. Now look at the central column, labeled "Narrower term." Notice how the very broad population has been narrowed. Similarly, "law enforcement" has been narrowed to police (there are many other types of law enforcement, such as FBI, Homeland Security, TSA, Customs and Immigration, sheriff's departments, and so on). Similarly, there are many kinds of behaviors and experiences that could be considered "responses," but the researcher is most interested in emotional responses. Now move to the third column. Can you see how each term is being narrowed yet again?

If we restated the topic now, after having narrowed it down a bit, it would look like this: Cherokee Indians' tolerance for stress when meeting traffic officers.

Let's work through another example, this time using the topic "Employees' productivity as a function of their managers' management styles."

You can see the key terms lined up in the first column. The other two columns are blank.

What would you ask yourself, if this were your topic, in order to narrow this down?

Questions to Ask for Narrowing a Topic

There are many questions you can ask yourself when you are narrowing your topic. A good opener is "So what do I really want to know about the concept?"

Another quite good question is to ask about your real interest or passion is about the concept or the population.

You can also find helpful terms by performing controlled vocabulary searches in library databases. You can find a nice tutorial on that method of searching in the Capella library at but whatever you ask yourself, keep your focus on what you truly most want to know and care about regarding the concept.

Now, let's get back to our example.

When the researcher asked herself what sort of employees and managers she was actually interested in, she realized it was service employees and managers. The more she pondered, and was helped by a quick check of the literature in her specialization, she realized that she was most interested in call center personnel. Then she tackled productivity . From her courses in management measurement, she knew that one way to think about productivity was days at work. But that seemed too dependent on factors outside the manager-employee relationship. She wanted a more fine-grained way to look at productivity, so she narrowed it to a specific measure, calls completed times minutes per call.

Then she took on management styl e. Knowing that there are many types, her first attempt at focusing this term was authoritarian style. That didn't satisfy her, and when she looked again at her topic, she realized that that word "function" was important. It implied to her that she was really interested in knowing how different management styles related to different degrees of productivity. At first, she put together a list of known management styles, but that felt intimidating. She decided to narrow it down to just two: authoritarian vs. flexible management style.

After all this, her topic now looked like this: Productivity as measured by calls completed times minutes per call in call center employees supervised by authoritarian managers compared to productivity in call center employees supervised by flexible managers.

She knew the wording was clunky and would need to be crafted better, but she had a much more focused topic. So far, we've been looking at two things about good research topics: what they should contain (concepts, relationships, and population), and how to narrow each element. In these narrowing exercises, we've focused on the concepts and the population. Now, let's turn our attention to the relationship . This is a very important element, because it offers an important clue about the nature of the study that might ensue.

Evaluating the Relationship Named in the Topic

Research asks all kinds of questions, and the relationship named in the research topic clues us into what kind of question the ensuing study will likely ask. Here are some questions you might ask in order to choose the right word to describe the relationship you're looking for.

What do you envision really doing?

• Looking at comparisons between variables or groups of people?
• Looking at relationships between two or more concepts?
• Looking at effects of one or more concept on another concept or group?
• Looking at outcomes of some process or treatment or condition?
• Looking at experiences?
• Developing a theory to explain some phenomenon?

For each of these (and there are other sorts of questions you can ask yourself), specific words can specify the relationship. Let's look at them.

If your topic compares two or more things compared with or some similar phrase indicates the relationship you want to know about. For instance, student retention rates in large urban school districts compared with small rural districts.

If your interest is about relationships between two or more concepts, try using words like relationship, in relation to, or other similar constructions. Here's an example: the frequency of church attendance in relation to socioeconomic status.

Suppose your interest is to see if one thing has an effect on something else. In that case, you can use that word, effect, or other words such as influence, impact, cause, predict, and the like. For example, the influence of tax policy on employment patterns in Midwestern communities.

An outcome is another version of a cause-and-effect relationship, specifically when you are interested in the final condition after some kind of process. For instance, the outcome of a training program. That word is excellent to use for the relationship, as in the outcome of training program A as measured by employee comprehension of corporate policies.

Are you interested in describing a certain experience, such as falling in love or being laid off work or having a baby or starting a new company? Having experiences is a very subjective thing, and the actual experience is a single thing—not one of a few variables. So there is no relationship to specify in such a topic, but the only way to learn about people's experiences is to ask them to describe them. So, words like descriptions of, accounts of, reports of, and the like can be very helpful. For instance, men's descriptions of their spiritual transformations when recovering from alcoholism.

Okay, we've covered the basics of how to craft a well-formed research topic. We've seen the marks of a good topic. They are:

• The key concepts are clearly stated and well-focused so that they can be profitably found in the literature.
• Second, the relationship, if any, between or among them is clearly stated. Even if there is no relationship, what you're really looking for (descriptions? accounts? reports?) can be seen in the wording.
• Third, the people you want to study, your population, is clearly stated and narrowed down to a workable point. You have all these points covered in a single phrase, and if after narrowing it down that phrase is awkward, you will work on crafting it into a more graceful form.

In a minute, you'll get to work crafting your own research topic, but first I want to show you why we emphasize the importance of narrowing and focusing the key concepts, relationships, and populations.

What Do You Do With the Research Topic?

The research topic is step 1 in the sequential process of research design. Once you have your topic in hand, step 2 is to take it to the library and begin searching for existing research and theory on the topic. Here's where your key concepts need to be well-defined and narrowly focused. You will be looking for all the existing research on those key concepts when you start.

At first, you'll investigate each of your key concepts individually, to find out what the existing literature has to say about them in and of themselves. Later, after you have developed a good working knowledge of the background concepts, you'll dig deeper into research linking the key concepts together.

At the third level, you'll follow the "breadcrumbs" all the way back to the earliest studies on your topic so that you will, ultimately, master that literature fully.

So your topic statement is the foundation. It organizes your various literature reviews. Searching on the key concepts (translated into various key words) will help you organize the content of your study.

Searching on the existing methodological literature about the relationship named in your topic will prepare you for your methodological decisions in later steps of research design.

There is an old Chinese proverb found in the I Ching and many other places: “Patience in the beginning brings success.” If you are careful and attentive, and work patiently to write your research topic, then rewrite it, then rewrite it again and again, you will have a solid foundation on which to start building your literature review. The topic is your beginning.

Remain patient and steady, and you will succeed.

Welcome to the Purdue OWL

Body paragraphs: Moving from general to specific information

Your paper should be organized in a manner that moves from general to specific information. Every time you begin a new subject, think of an inverted pyramid - The broadest range of information sits at the top, and as the paragraph or paper progresses, the author becomes more and more focused on the argument ending with specific, detailed evidence supporting a claim. Lastly, the author explains how and why the information she has just provided connects to and supports her thesis (a brief wrap-up or warrant).

Moving from General to Specific Information

The four elements of a good paragraph (TTEB)

A good paragraph should contain at least the following four elements: T ransition, T opic sentence, specific E vidence and analysis, and a B rief wrap-up sentence (also known as a warrant ) –TTEB!

• A T ransition sentence leading in from a previous paragraph to assure smooth reading. This acts as a hand-off from one idea to the next.
• A T opic sentence that tells the reader what you will be discussing in the paragraph.
• Specific E vidence and analysis that supports one of your claims and that provides a deeper level of detail than your topic sentence.
• A B rief wrap-up sentence that tells the reader how and why this information supports the paper’s thesis. The brief wrap-up is also known as the warrant. The warrant is important to your argument because it connects your reasoning and support to your thesis, and it shows that the information in the paragraph is related to your thesis and helps defend it.

Supporting evidence (induction and deduction)

Induction is the type of reasoning that moves from specific facts to a general conclusion. When you use induction in your paper, you will state your thesis (which is actually the conclusion you have come to after looking at all the facts) and then support your thesis with the facts. The following is an example of induction taken from Dorothy U. Seyler’s Understanding Argument :

There is the dead body of Smith. Smith was shot in his bedroom between the hours of 11:00 p.m. and 2:00 a.m., according to the coroner. Smith was shot with a .32 caliber pistol. The pistol left in the bedroom contains Jones’s fingerprints. Jones was seen, by a neighbor, entering the Smith home at around 11:00 p.m. the night of Smith’s death. A coworker heard Smith and Jones arguing in Smith’s office the morning of the day Smith died.

Conclusion: Jones killed Smith.

Here, then, is the example in bullet form:

• Conclusion: Jones killed Smith
• Support: Smith was shot by Jones’ gun, Jones was seen entering the scene of the crime, Jones and Smith argued earlier in the day Smith died.
• Assumption: The facts are representative, not isolated incidents, and thus reveal a trend, justifying the conclusion drawn.

When you use deduction in an argument, you begin with general premises and move to a specific conclusion. There is a precise pattern you must use when you reason deductively. This pattern is called syllogistic reasoning (the syllogism). Syllogistic reasoning (deduction) is organized in three steps:

• Major premise
• Minor premise

In order for the syllogism (deduction) to work, you must accept that the relationship of the two premises lead, logically, to the conclusion. Here are two examples of deduction or syllogistic reasoning:

• Major premise: All men are mortal.
• Minor premise: Socrates is a man.
• Conclusion: Socrates is mortal.
• Major premise: People who perform with courage and clear purpose in a crisis are great leaders.
• Minor premise: Lincoln was a person who performed with courage and a clear purpose in a crisis.
• Conclusion: Lincoln was a great leader.

So in order for deduction to work in the example involving Socrates, you must agree that (1) all men are mortal (they all die); and (2) Socrates is a man. If you disagree with either of these premises, the conclusion is invalid. The example using Socrates isn’t so difficult to validate. But when you move into more murky water (when you use terms such as courage , clear purpose , and great ), the connections get tenuous.

For example, some historians might argue that Lincoln didn’t really shine until a few years into the Civil War, after many Union losses to Southern leaders such as Robert E. Lee.

The following is a clear example of deduction gone awry:

• Major premise: All dogs make good pets.
• Minor premise: Doogle is a dog.
• Conclusion: Doogle will make a good pet.

If you don’t agree that all dogs make good pets, then the conclusion that Doogle will make a good pet is invalid.

When a premise in a syllogism is missing, the syllogism becomes an enthymeme. Enthymemes can be very effective in argument, but they can also be unethical and lead to invalid conclusions. Authors often use enthymemes to persuade audiences. The following is an example of an enthymeme:

If you have a plasma TV, you are not poor.

The first part of the enthymeme (If you have a plasma TV) is the stated premise. The second part of the statement (you are not poor) is the conclusion. Therefore, the unstated premise is “Only rich people have plasma TVs.” The enthymeme above leads us to an invalid conclusion (people who own plasma TVs are not poor) because there are plenty of people who own plasma TVs who are poor. Let’s look at this enthymeme in a syllogistic structure:

• Major premise: People who own plasma TVs are rich (unstated above).
• Minor premise: You own a plasma TV.
• Conclusion: You are not poor.

To help you understand how induction and deduction can work together to form a solid argument, you may want to look at the United States Declaration of Independence. The first section of the Declaration contains a series of syllogisms, while the middle section is an inductive list of examples. The final section brings the first and second sections together in a compelling conclusion.

What Is a Topic Sentence?

A topic sentence is the first sentence of a paragraph that conveys the general concept or theme of the work.

It includes enough information to support numerous subtopics and examples but doesn't obscure the purpose of the text. A strong topic sentence is brief , powerful , and emphasizes critical thought with supporting information.

• The positioning of the topic sentence varies depending on the author's intentions. Starting with the topic sentence guides readers to the key message immediately.
• When significant details lead to a generalization, it is sensible to place the topic sentence at the end of the paragraph.

The Purpose of a Topic Sentence

A topic sentence's purpose is to direct the reader to the subject of the paragraph . It presents the particular issue of the text section and relates to the essay's thesis statement . Moreover, topic sentences structure an essay by dividing it into key points.

Topic Sentence Vs. Thesis

Although the topic and thesis statements should be precise, concise, and explicit, they differ:

✍️ How to Write a Body Paragraph Topic Sentence

There are four practical steps you have to take to create a solid topic sentence .

Determine the main idea of the paragraph . To write a topic sentence, you must understand the subject matter of your paper. A thesis statement will help you identify the fundamental concept of the paragraph.

Create a statement . Creating a statement that includes what and why questions and leads to your core idea is essential. You must describe the issue and explain why it is crucial.

Formulate the topic sentence . Write a statement that introduces the subtopic of a particular paragraph and leads readers back to the thesis statement. You can keep using the what and why structure as you write new topic sentences for each section.

Add transitions between paragraphs . Topic sentences should also establish a throughline in your research paper by drawing on the previous sections. Utilize transition words to refer to the previous paragraph while heading to the next section.

A topic sentence consists of 2 parts:

• The topic . This is the paragraph's subject, indicating what the paragraph is about.
• The controlling idea. This is the point that leads to the supporting arguments and limits its scope.

Here are some examples from our topic sentence generator with the topics in bold and the controlling ideas in italic .

A Good Topic Sentence Features

A solid topic sentence has the following features:

• Novelty . A good topic sentence is well-focused on a fresh concept since it always provides new information for the reader.
• Specificity . If the beginning of a paragraph is too broad, the reader will be confused about what to expect next.
• Strength . The topic sentence should provide explicit and unambiguous information.

Writing Resources

Constructing effective research paragraphs.

This handout is available for download in DOCX format and PDF format .

A paragraph is a collection of related sentences dealing with a single topic. This handout breaks the research paragraph down into its conceptual and structural components.

Writing in all disciplines requires a researcher to place his or her ideas in conversation with other positions in the field. In order to do this, the writer is responsible for making a claim about the field and then persuasively defending that claim using evidence from published research on the same topic. This is the goal of a research paragraph. A successful research paragraph will effectively convey both the scope of the investigation and the state of the field . Its composition will consist of a topic sentence , evidence taken from sources, stitching that effectively links those sources to one another, a citation for each source, and a conclusion .

Conceptual Components

State of the field.

In order to make a claim about how your argument contributes to a given field, you must first demonstrate to your reader what the scholarly conversation in that field looks like: settled arguments, unresolved debates, gaps in investigation, etc. Establishing the state of the field early in your essay will allow you to motivate your argument by showing how your ideas expand or challenge our current understanding.

Any argument will be more meaningful to some fields than it is to others. The range of sources you include in your research paragraph conveys which fields your argument is most relevant to. A broad collection of sources will suggest that your argument has a wide scope, that it engages and contributes to a variety of subject areas. A narrow set of sources will suggest a more limited—though not necessarily less important—contribution to the field.

Structural Components

Topic sentence (summary of the field).

The goal of any topic sentence is to make a claim that you will defend in the body of the paragraph. Since the goal of a research paragraph is to offer a summary of the field, the topic sentence should assert a clear position about the state of current research.

In order to persuade a reader, any claim about the state of a particular field must be supported using evidence from published work in that field. In the sciences and social sciences, this evidence often takes the form of summaries of major positions (often backed up with multiple citations). The humanities, on the other hand, tend to rely more on direct quotation of relevant sources.

Simply quoting a variety of sources in succession will not produce a persuasive argument about the state of your field of research. You must convey how the ideas in each source are related to one another. This type of argument demands the use of active verbs, clear explanation of each author’s key terms, and nuanced description of the conceptual links between each source’s ideas.

Citing the evidence you offer conveys the source of your ideas and saves you from the dishonest practice of passing others’ ideas off as your own. In-text parenthetical citations are conventional in most fields (history, which uses footnotes, is one exception). In this method of citation, the source author’s name and the page number of the idea and are included in your text and refer the reader to a full entry in your list of works cited should he or she want to seek out more information. In the sciences and social sciences, in-text citations also include the source’s date of publication.

Conclusion (evolved summary)

As you approach the end of your research paragraph, your evidence will have supported the claim made in your topic sentence about the larger field from which those sources were drawn. As a result, you will want to revisit that initial claim at the end of the paragraph for some additional discussion. Returning to the ideas in your topic sentence at the conclusion of your paragraph serves two primary purposes:

• to state an evolved—more nuanced or specific—version of your initial claim in light of the evidence you have offered, and…
• to remind your reader of this claim as you move into the next paragraph that will, presumably, build upon these ideas in some way.

Example Research Paragraph

Here is an example of a research paragraph that we will analyze sentence by sentence:

Commentators have conventionally approached ethnic jokes using the superiority theory of humor, which claims that people laugh when a joke makes them feel above the object of ridicule. Thomas Hobbes characterizes this emotion as “sudden glory arising from some sudden conception of some eminency in ourselves, by comparison with the infirmity of others, or with our own formerly” (47). Applying this concept to ethnic humor, John Morreall states that people derive this “sudden glory” from “mocking [immigrants] in great detail about their race, accent, clothing, ugliness, etc.” (10). Leon Rappoport further clarifies how stereotypes and ethnicity-based mockery embody the superiority theory by explaining that these disparaging jokes often employ “polar opposite adjectives...[so that] only [the] negative end of the pair is emphasized [and] the positive end always remains implicitly understood as characteristic of the ‘superior’ joke teller” (33). With these jokes, the overt debasement of immigrants simultaneously elevates the person making the joke. Consequently, the opposing adjectives noted by Rappoport suggest a hierarchy between the person who tells the joke and the people at the butt of the joke.

Example Research Paragraph: Structural Components

Example Research Paragraph: Analysis

Topic sentence (summary of the field).

• Commentators have conventionally approached ethnic jokes using the superiority theory of humor, which claims that people laugh when a joke makes them feel above the object of ridicule.

This essay’s thesis is: “Taking advantage of their multi-ethnic identities, [Margaret] Cho and [Carlos] Mencia introduce a new version of ethnic humor that does not promote a cultural hierarchy, combining traditional superiority humor with comic correction by mocking the majority and the minority in the same routine.” Since the author seeks to argue that Cho and Mencia create “a new version of ethnic humor,” she is committed to demonstrating agreement about the old version in order to show how their routines work differently. This scholarly consensus is what she seeks to establish in this, her first body paragraph. As a result, the topic sentence makes a straightforward claim about traditional approaches to the field that she can then support in the body of the paragraph using material from her secondary sources.

• Thomas Hobbes characterizes this emotion as “sudden glory arising from some sudden conception of some eminency in ourselves, by comparison with the infirmity of others, or with our own formerly” (47).
• John Morreall states that people derive this “sudden glory” from “mocking [immigrants] in great detail about their race, accent, clothing, ugliness, etc.” (10).
• …by explaining that these disparaging jokes often employ “polar opposite adjectives...[so that] only [the] negative end of the pair is emphasized [and] the positive end always remains implicitly understood as characteristic of the ‘superior’ joke teller”…

The author quotes three different sources as evidence for her claim that traditional ethnic humor relies on assertions of cultural superiority. However, she does not simply cite three roughly identical quotes. She evolves her ideas, thereby broadening the reader’s perspective and giving herself more source material to work in the later stages of her argument. She begins by citing a broad version of the superiority theory before turning to a second quote that situates that theory within her more specific context of ethnic humor. In the final quotation, she increases the specificity of her ideas yet again by introducing a version of the same theory that identifies “polar opposite adjectives” as the linguistic mechanism of superiority-based ethnic humor. The trajectory of ideas in this paragraph moves from broad to specific, establishing an initial overview and then working toward additional clarity.

• Applying this concept to ethnic humor…
• further clarifies how stereotypes and ethnicity-based mockery embody the superiority theory…

In the lead-ins to her quotes, the author is careful not only to prepare her reader to understand each idea, but also to link those ideas to the ones that came before. Having just introduced a theory of humor based on superiority, the author forges a conceptual link by telling her reader that the ensuing quote will apply this concept to the more specific case of ethnic humor. After using that quote to establish that ethnic humor conventionally relies on assertions of cultural superiority, she indicates that her next quote “further clarifies” the issue, which it does by identifying opposed adjectives as the precise mechanism of superiority-based ethnic humor.

• Thomas Hobbes … (47).
• John Morreall … (10).
• Leon Rappoport … (33).

The author uses in-text parenthetical citations, which are conventional in most academic fields (History tends to be the exception). She identifies the name of each source before quoting it so that the reader knows who is speaking when the source’s voice enters her argument. Because she has been careful to give each source’s name in her text, she only needs to note the page number in the parentheses. Citing the name of each source allows the reader to locate its title in this essay’s list of works cited (alphabetized by author’s last name), and the page numbers allow the reader to locate the specific quote within that text.

• With these jokes, the overt debasement of immigrants simultaneously elevates the person making the joke. Consequently, the opposing adjectives noted by Rappoport suggest a hierarchy between the person who tells the joke and the people at the butt of the joke.

Having worked through a context of carefully chosen sources, the author does not end her paragraph with the final quote. Instead, she returns to the claim she established in the first sentence, this time in an evolved form. The sources she has quoted throughout her paragraph allow her to move beyond a simple restatement of her initial claim that conventional ethnic humor asserts the superiority of the joke teller’s ethnicity. In her discussion of the adjectives that allow for simultaneous elevation of one culture and debasement of another, the author furthers her initial claim that ethnic humor establishes a cultural hierarchy by demonstrating how .

What is a Topic Sentence?

A topic sentence is the first sentence of a paragraph in an essay that introduces the main idea or topic of that paragraph. It serves as a roadmap for the reader, letting them know what to expect in the upcoming paragraph. 

Purpose of Topic Sentence

The purpose of a topic sentence is to clearly and concisely convey the main point of the paragraph to the reader. 

It helps to guide the reader through the essay, making it easier for them to follow the overall argument or narrative.

Features of a Good Topic Sentence

A good topic sentence has a few key features. Let’s take a look: 

• Expresses the main idea of the paragraph or essay clearly and concisely.
• Is specific and focused , avoiding vague or overly general statements.
• Introduces the main point and is typically located at the beginning of the paragraph or essay.
• Presents a claim or position that is arguable or debatable, which the rest of the paragraph or essay will support.
• Can be a complete sentence or a concise phrase that effectively conveys the main idea.
• Is relevant to the thesis statement and overall topic of the essay.
• Engages the reader by creating interest and highlighting the significance of the topic.
• Is well-written and avoids grammar and spelling errors.

Types of Topic Sentences

There are several different types of topic sentences that can be used in writing to introduce the reader through a paragraph or essay.

Simple Statement Topic Sentence This is the most common type of topic sentence, which straightforwardly states the main point or idea of the paragraph or essay.

Example: The rise of social media has revolutionized the way people communicate with each other.

Complex Topic Sentence This type of topic sentence is more nuanced and may require some explanation or elaboration to fully understand.

Example: While the rise of social media has had many positive effects on communication, it has also led to concerns about privacy and online harassment.

Pivot Topic Sentence A pivot topic sentence begins by connecting the current paragraph or idea to the previous one, before pivoting to introduce a new point or idea.

Example: Building on the idea of social media's impact on communication, it is important to consider how it has also affected business and marketing strategies.

Question Topic Sentence A question topic sentence poses a question that the rest of the paragraph or essay will answer or explore.

Example: How has social media changed the way businesses interact with customers and advertise their products?

Command Topic Sentence This type of topic sentence gives a directive or instruction, often used in persuasive or argumentative essays.

Example: Support local businesses by shopping at independently owned stores instead of large chains.

How to Write a Topic Sentence?

Here are a few instructions to help you write a good topic sentence. 

Step#1 Clearly State The Main Idea

A topic sentence is the first paragraph of the paragraph. It must clearly explain the particular subject that would be discussed in the paragraph. This should be stated in very clear language so that the reader can easily understand the idea. 

Also, it should include a bit of your personal opinion and also the main idea. 

Step#2 Hook Your Reader

Grab your reader's attention with an intriguing topic sentence. It would excite and make the reader curious about the content and convince them to read the particular part. 

Look out for some amazing hook examples and see what fits your essay type. 

Use a meaningful and relevant question or a fact as a topic sentence of the paragraph. Make sure that you have identified your audience and are developing everything accordingly. 

Step#3 Keep It Short and Precise

The paragraph topic sentence must be expressive enough that a reader understands your point of view effortlessly. This is only possible if you keep everything to the point, short, and meaningful. 

Choose the words in such a way that they help you express your idea in an ideal way. Avoid using complex sentences and use independent clauses.  

A topic sentence acts as a link between a paragraph and the main thesis statement. It should be specific and connected to the overall essay. Keeping it short and precise helps maintain the paragraph's flow and its relevance to the rest of the writing.

Step#4 Give A Reasonable Opinion

The body paragraph explains a topic sentence. This is why it is important that you should write this sentence in such a way that it can be explained in the paragraph.  If you are mentioning a fact in the topic statement, make sure that you have authentic evidence to support it. 

While the topic sentence is an integral part of the paragraph, it should stand out and possess a distinctiveness that sets it apart from the other sentences. This can be achieved by employing transition words and establishing connections between sentences.

Step#5 Use The Topic Sentence As A Transition

The topic sentences that serve as transition sentences can be considered a guide for the readers. This way, they can help the reader to move through the essay in a flow. 

Write this sentence in such a way that it creates a gateway between the previous paragraph and the rest of the essay. Moreover, it will also help keep the essay organized, and the reader understands the point of a paragraph.

Step#6 Look For Some Good Examples

Examples can help you learn a thing in a better way. If you are new to writing topic sentences, it can help to look at some examples. Find some great examples of topic sentences relevant to your essay topic.

Difference Between Topic Sentence and Thesis Sentence

Here's a table outlining the differences between a topic sentence and a thesis statement:

Good Topic Sentence Examples

Here are ten examples of good topic sentences:

•  "Despite the advancements in technology, traditional forms of communication are still essential in today's society."
• "The theme of power is prevalent throughout Shakespeare's play, Macbeth."
• "In recent years, there has been a growing concern over the impact of climate change on our planet."
• "The legalization of marijuana has been a topic of debate for many years." "Education is the key to success in life."
• "The rise of social media has greatly impacted the way we communicate with one another."
• "The effects of childhood trauma can have a lasting impact on mental health."
• "The concept of justice is explored in depth in Harper Lee's To Kill a Mockingbird."
• "Eating a balanced diet is crucial for maintaining good health."
• "The Industrial Revolution had a profound effect on the world as we know it today."

The Bottom Line!

An opening sentence is crucial to grab your reader's attention and set the tone for your piece of writing. The topic sentence introduces the controlling idea and acts as an important sentence in the essay outline. 

Effective topic sentences are necessary for a well-structured and organized essay. It's an integral part of the writing process that should not be overlooked. 

Make sure to spend time crafting a compelling topic sentence that clearly conveys your main point and guides your readers throughout your essay. You can even take ideas from an AI essay generator to get started.

TOPIC SENTENCE/ In his numerous writings, Marx critiques capitalism by identifying its flaws. ANALYSIS OF EVIDENCE/ By critiquing the political economy and capitalism, Marx implores his reader to think critically about their position in society and restores awareness in the proletariat class. EVIDENCE/ To Marx, capitalism is a system characterized by the “exploitation of the many by the few,” in which workers accept the exploitation of their labor and receive only harm of “alienation,” rather than true benefits ( MER 487). He writes that “labour produces for the rich wonderful things – but for the worker it produces privation. It produces palaces—but for the worker, hovels. It produces beauty—but for the worker, deformity” (MER 73). Marx argues capitalism is a system in which the laborer is repeatedly harmed and estranged from himself, his labor, and other people, while the owner of his labor – the capitalist – receives the benefits ( MER 74). And while industry progresses, the worker “sinks deeper and deeper below the conditions of existence of his own class” ( MER 483).  ANALYSIS OF EVIDENCE/ But while Marx critiques the political economy, he does not explicitly say “capitalism is wrong.” Rather, his close examination of the system makes its flaws obvious. Only once the working class realizes the flaws of the system, Marx believes, will they - must they - rise up against their bourgeois masters and achieve the necessary and inevitable communist revolution.

Not every paragraph will be structured exactly like this one, of course. But as you draft your own paragraphs, look for all three of these elements: topic sentence, evidence, and analysis.

How to Write a Thesis Statement | 4 Steps & Examples

Published on January 11, 2019 by Shona McCombes . Revised on August 15, 2023 by Eoghan Ryan.

A thesis statement is a sentence that sums up the central point of your paper or essay . It usually comes near the end of your introduction .

Your thesis will look a bit different depending on the type of essay you’re writing. But the thesis statement should always clearly state the main idea you want to get across. Everything else in your essay should relate back to this idea.

You can write your thesis statement by following four simple steps:

• Start with a question
• Write your initial answer
• Develop your answer
• Refine your thesis statement

A thesis statement summarizes the central points of your essay. It is a signpost telling the reader what the essay will argue and why.

The best thesis statements are:

• Concise: A good thesis statement is short and sweet—don’t use more words than necessary. State your point clearly and directly in one or two sentences.
• Contentious: Your thesis shouldn’t be a simple statement of fact that everyone already knows. A good thesis statement is a claim that requires further evidence or analysis to back it up.
• Coherent: Everything mentioned in your thesis statement must be supported and explained in the rest of your paper.

Prevent plagiarism. Run a free check.

The thesis statement generally appears at the end of your essay introduction or research paper introduction .

The spread of the internet has had a world-changing effect, not least on the world of education. The use of the internet in academic contexts and among young people more generally is hotly debated. For many who did not grow up with this technology, its effects seem alarming and potentially harmful. This concern, while understandable, is misguided. The negatives of internet use are outweighed by its many benefits for education: the internet facilitates easier access to information, exposure to different perspectives, and a flexible learning environment for both students and teachers.

You should come up with an initial thesis, sometimes called a working thesis , early in the writing process . As soon as you’ve decided on your essay topic , you need to work out what you want to say about it—a clear thesis will give your essay direction and structure.

You might already have a question in your assignment, but if not, try to come up with your own. What would you like to find out or decide about your topic?

For example, you might ask:

After some initial research, you can formulate a tentative answer to this question. At this stage it can be simple, and it should guide the research process and writing process .

Now you need to consider why this is your answer and how you will convince your reader to agree with you. As you read more about your topic and begin writing, your answer should get more detailed.

In your essay about the internet and education, the thesis states your position and sketches out the key arguments you’ll use to support it.

The negatives of internet use are outweighed by its many benefits for education because it facilitates easier access to information.

In your essay about braille, the thesis statement summarizes the key historical development that you’ll explain.

The invention of braille in the 19th century transformed the lives of blind people, allowing them to participate more actively in public life.

A strong thesis statement should tell the reader:

• Why you hold this position
• What they’ll learn from your essay
• The key points of your argument or narrative

The final thesis statement doesn’t just state your position, but summarizes your overall argument or the entire topic you’re going to explain. To strengthen a weak thesis statement, it can help to consider the broader context of your topic.

These examples are more specific and show that you’ll explore your topic in depth.

Your thesis statement should match the goals of your essay, which vary depending on the type of essay you’re writing:

• In an argumentative essay , your thesis statement should take a strong position. Your aim in the essay is to convince your reader of this thesis based on evidence and logical reasoning.
• In an expository essay , you’ll aim to explain the facts of a topic or process. Your thesis statement doesn’t have to include a strong opinion in this case, but it should clearly state the central point you want to make, and mention the key elements you’ll explain.

A thesis statement is a sentence that sums up the central point of your paper or essay . Everything else you write should relate to this key idea.

The thesis statement is essential in any academic essay or research paper for two main reasons:

Follow these four steps to come up with a thesis statement :

• Ask a question about your topic .
• Write your initial answer.
• Develop your answer by including reasons.
• Refine your answer, adding more detail and nuance.

The thesis statement should be placed at the end of your essay introduction .

Understand the Basics of Sentence Structure

Understanding the basics of sentence structure is important in academic writing. Every sentence in your research paper is a building block, contributing to the clarity and persuasiveness of your argument. A good sentence begins with a clear focus: every word should help convey your main idea directly and effectively.

First, recognize the importance of a strong subject and verb combination. The subject of your sentence performs the action, which is described by the verb. Ensuring these elements are clear and concise prevents ambiguity and keeps the reader on their toes. For example: “The experiment demonstrates…” is more direct than saying: “It is demonstrated by the experiment that…”

Think about the structure of your sentences. A well-crafted sentence follows a logical pattern: subject, verb, object. Following this structure can make your writing easier while enhancing the article’s readability.

Finally, remember that every sentence you write should support the main point of your paragraph. Think of each sentence as a mini-argument that adds to your thesis, logically linking your ideas. Mastering these basics is the first step in ensuring that every sentence you write contributes substance.

Techniques for Enhancing Sentences

No, we weren’t about to leave you hanging. Here are some practical techniques that you can use to make each sentence add value to your research paper.

Achieving clarity is extremely important, especially in scientific writing and within your thesis statement. The argument must be clear to the reader immediately. One common issue is the overuse of complex sentences that muddy your points. Counter this by focusing on using active voice rather than passive voice. Passive voice can simply obscure “who” is performing the action.

Here’s an example: “The researcher conducted the experiment” (active) is clearer than: “The experiment was conducted by the researcher” (passive).

Also, when explaining processes or results that occurred in your study, past tense should be used consistently to maintain clarity. Ensure every verb in your sentence drives home a clear idea, supporting the main argument. So, when it comes to clarity, be sure to choose the right verb tense.

Sentence structure is an important part of keeping your academic articles engaging. The general rule is to mix different types of sentences to keep the reader’s interest and highlight key points.

Start by varying the length of your sentences: pair a shorter, impactful sentence with a longer, more descriptive one. This can prevent your writing from becoming boring. After a punchy statement, for example, extend the next sentence with additional details.

It’s also important to experiment with different starts to sentences . Using an adverb, an adjective, or a phrase to lead your thoughts can be helpful. Discussing your topics with various verbs also adds rhythm and dynamics to your text. Do this carefully, though: getting too creative with your diction can make a sentence more complex than it needs to be.

Trust us, it’s worth the effort to rephrase sentences to avoid repetitive structures and ensure your ideas are expressed as clearly and vividly as possible. This is key to crafting a compelling narrative for your article.

Transitions

Powerful transitions are the glue that holds your essay together, guiding the reader smoothly from one idea to the next. The first sentence of each paragraph should serve as a bridge from the previous paragraph. The most important point of a new section should be introduced clearly and succinctly.

This helps the reader follow your argument without struggling through abrupt changes and disconnected points. For example, if one paragraph discusses a specific aspect of your research, the next could link that aspect to another, deepening the reader’s understanding of the topic.

Within a paragraph, each sentence should logically flow to the next , using transition words and phrases to signal the connection between ideas. Using transitions effectively clarifies the relationship between paragraphs and sentences. It also reinforces the overall structure of your paper, ensuring each point contributes meaningfully to your thesis.
