These vs Thesis: Which One Is The Correct One?

these vs thesis

Considering discussing the usage of “these” versus “thesis,” it is important to understand the distinctions between these two words. “These” is a pronoun that refers to a specific group of people or things that are nearby or have just been mentioned. On the other hand, “thesis” is a noun that refers to a statement or theory that is put forward and supported by arguments in a written work. Both words have their own unique meanings and functions in the English language.

These: This pronoun is used to refer to a specific group of people or things that are either physically close or have been previously mentioned. It is often used to indicate proximity or to introduce a set of items. For example, “These are the books I borrowed from the library” or “These are the facts that support my argument.” In essence, “these” helps to identify and specify a particular set of objects or individuals.

Thesis: In contrast, “thesis” is a noun that has a more specific meaning. It refers to a statement or theory that is put forward and supported by arguments in a written work, such as an essay or a research paper. A thesis is typically the central idea or main argument of a piece of writing. It serves as a guiding principle and provides a clear focus for the content that follows. A well-constructed thesis statement helps to establish the purpose and direction of an academic or scholarly work.

Understanding the proper usage of “these” and “thesis” is crucial for effective communication and writing. While “these” is a pronoun that points to a specific group or objects, “thesis” is a noun that represents a central argument in a written work. In the following sections, we will explore the usage, examples, and common mistakes associated with these two words.

The Definitions

In order to fully understand the distinction between “these” and “thesis,” it is essential to establish clear definitions for both terms. Let us delve into each of these terms individually:

Define These

When we refer to “these,” we are referring to a demonstrative pronoun that is used to indicate or point out specific people, things, or ideas. It serves as a way to highlight or draw attention to a particular set of objects or concepts. By using “these,” we are emphasizing the proximity or closeness of the subject matter being discussed. It is worth noting that “these” is the plural form of “this,” which is used to refer to a singular object or idea.

To illustrate this further, let us consider an example:

Imagine you are holding a group of books in your hand. By saying, “These books are fascinating,” you are explicitly referring to the books that are within your immediate reach or visible to you. The word “these” helps to distinguish the books you are pointing at from other books that may be present but not within your immediate vicinity.

In summary, “these” is a demonstrative pronoun that directs attention to a specific group of objects, ideas, or individuals that are within close proximity to the speaker or writer.

Define Thesis

On the other hand, a thesis is a fundamental component of academic writing, particularly in research-based disciplines. It is a concise statement or proposition that serves as the main argument or central idea of a scholarly work. A thesis provides a clear direction and focus for the entire piece of writing, guiding the reader through the author’s thought process and supporting evidence.

A well-crafted thesis should be specific, debatable, and supported by logical reasoning and evidence. It serves as the backbone of an academic paper, presenting the author’s position on a topic and providing a framework for the subsequent analysis and discussion.

Let us consider an example to better grasp the concept of a thesis:

Suppose you are writing an essay on climate change. Your thesis statement could be: “The increasing emission of greenhouse gases is the primary cause of global warming, and urgent measures must be taken to mitigate its detrimental effects.” This thesis statement clearly presents your stance on the issue and sets the tone for the rest of your essay, guiding your research and analysis.

A thesis is a concise statement that encapsulates the main argument or central idea of an academic work, providing direction and focus for the entire piece of writing.

How To Properly Use The Words In A Sentence

In order to effectively communicate ideas, it is crucial to understand how to properly use the words “these” and “thesis” in a sentence. While they may sound similar, their meanings and usage differ significantly. Let’s explore the correct usage of each word in detail.

How To Use “These” In A Sentence

The word “these” is a demonstrative pronoun that is used to indicate or point to specific people, things, or ideas that are nearby or have been previously mentioned. It is the plural form of “this.”

When using “these” in a sentence, it is important to remember that it should be followed by a noun or a noun phrase. This helps to clarify the specific objects or concepts being referred to. Here are a few examples:

  • These flowers are beautiful.
  • I bought these books yesterday.
  • Can you pass me these pencils?

As seen in the examples, “these” is used to specify and identify particular items that are within reach or have been mentioned in the context. It adds precision and clarity to the sentence, allowing the reader or listener to understand exactly what is being referred to.

How To Use “Thesis” In A Sentence

The word “thesis” is a noun that refers to a statement or a theory that is put forward as a premise to be proved or maintained. It is commonly used in academic and research contexts.

When using “thesis” in a sentence, it is typically introduced with a verb such as “present,” “support,” or “develop.” This helps to convey the action of proposing or discussing a specific idea or argument. Here are a few examples:

  • The author’s thesis explores the impact of climate change on biodiversity.
  • She presented her thesis on the effects of social media on mental health.
  • The professor is currently working on his doctoral thesis.

As demonstrated in these examples, “thesis” is used to refer to a formal statement or proposition that is being researched, analyzed, or argued. It represents a central idea or concept that serves as the foundation for further discussion or investigation.

More Examples Of These & Thesis Used In Sentences

In this section, we will explore various examples of how the words “these” and “thesis” can be used in sentences. By examining these examples, we can gain a better understanding of their proper usage and context.

Examples Of Using “These” In A Sentence:

  • These books on the shelf belong to my personal collection.
  • I can’t believe these cookies are homemade; they taste absolutely delicious!
  • These shoes are the latest fashion trend, everyone wants to get their hands on a pair.
  • These flowers in the garden bloom beautifully during springtime.
  • These students have shown exceptional dedication to their studies.

Examples Of Using “Thesis” In A Sentence:

  • The professor praised the student’s thesis for its originality and well-supported arguments.
  • Her thesis explores the relationship between art and identity in modern society.
  • The author’s thesis challenges conventional wisdom and offers a fresh perspective on the topic.

  • The committee members were impressed by the depth and coherence of her thesis presentation.

These examples demonstrate the diverse ways in which “these” and “thesis” can be effectively used in sentences. Whether referring to objects or ideas, it is crucial to use these words accurately to convey our intended meaning.

Common Mistakes To Avoid

When it comes to writing, it is crucial to understand the subtle differences between similar words and phrases. One such pair that often confuses writers is “these” and “thesis.” While they may sound alike, they have distinct meanings and should not be used interchangeably. Unfortunately, many people make this mistake, leading to confusion and undermining the clarity of their writing. In this section, we will highlight the common mistakes people make when using “these” and “thesis” interchangeably, along with explanations of why such usage is incorrect.

Mistake 1: Using “These” Instead Of “Thesis”

One common mistake is using “these” when referring to a thesis statement or a central argument in an academic or research paper. The word “these” is a demonstrative pronoun used to indicate specific items or ideas in proximity to the speaker or writer. On the other hand, a thesis refers to a statement or theory put forward to be discussed or proved. Confusing the two can result in a lack of clarity and weaken the overall argument of a piece of writing.

For example, consider the following sentence:

“These are the main points I will discuss in my research paper.”

In this sentence, using “these” instead of “thesis” creates ambiguity and fails to convey the writer’s intended meaning. To correct this mistake, one should replace “these” with “thesis,” as follows:

“This is the main thesis I will discuss in my research paper.”

By using the correct term, the writer ensures that their readers understand the central argument they will be exploring in their paper.

Mistake 2: Using “Thesis” Instead Of “These”

Conversely, another mistake commonly made is using “thesis” when referring to a set of specific items or ideas. As mentioned earlier, a thesis is a specific statement or theory, whereas “these” is a pronoun used to indicate multiple items or ideas. Incorrectly substituting “thesis” for “these” can result in confusion and miscommunication.

Here’s an example to illustrate this mistake:

“The thesis are the key findings of my study.”

In this sentence, using “thesis” instead of “these” creates confusion as the word “thesis” refers to a singular concept, not multiple findings. To rectify this error, one should replace “thesis” with “these,” as shown below:

“These are the key findings of my study.”

By using the appropriate term, the writer clarifies that they are referring to multiple findings rather than a single statement.

By avoiding these common mistakes and using “these” and “thesis” correctly, writers can enhance the clarity and effectiveness of their communication. Understanding the distinctions between these words is essential for producing well-crafted and coherent writing.

Context Matters

When it comes to the choice between “these” and “thesis,” context plays a crucial role in determining which term is more appropriate to use. Both words have distinct meanings and usage, and understanding their nuances in various contexts is essential to effective communication. Let’s explore how the choice between “these” and “thesis” can vary based on different situations.

Academic Writing

In the realm of academic writing, the term “thesis” holds significant importance. A thesis refers to a statement or proposition that is put forward and supported by arguments in an essay or research paper. It serves as the central claim or main idea that the author aims to prove or discuss throughout their work. In this context, “thesis” is a formal and specific term used primarily in scholarly discourse.

On the other hand, the word “these” is more commonly used as a demonstrative pronoun or adjective in academic writing. It is employed to refer to specific things or ideas that have already been mentioned or are about to be introduced. For instance, a sentence like, “These findings support the hypothesis proposed in the previous section” uses “these” to refer back to previously mentioned findings.

Everyday Language

Outside the realm of academia, the choice between “these” and “thesis” shifts to a more general usage. In everyday language, “these” is commonly used as a demonstrative pronoun or adjective to point out or refer to multiple objects or ideas that are nearby or have been previously mentioned. For example, “I love these flowers” or “These are my favorite books.”

On the other hand, the term “thesis” is not commonly used in everyday conversation unless specifically discussing academic topics or engaging in formal discussions. It is more likely to be encountered in contexts such as debates, presentations, or when referring to a specific academic work.

Business And Professional Settings

In business and professional settings, the choice between “these” and “thesis” depends on the specific context and the nature of the communication. “These” is often used to refer to multiple items, concepts, or ideas that are being discussed or presented. For instance, in a business presentation, one might say, “These strategies have proven successful in the past.”

On the other hand, “thesis” is rarely used in a business or professional context unless specifically referring to a formal research document or an academic discussion within the field. It is more commonly associated with the academic realm and may not be widely understood or relevant in most business settings.

The choice between “these” and “thesis” is heavily influenced by the context in which they are used. While “thesis” is primarily associated with academic writing and formal discussions, “these” is a more versatile term used in everyday language and various professional settings. Understanding the appropriate usage of each term ensures effective communication and avoids confusion.

Exceptions To The Rules

While the usage of “these” and “thesis” generally follows certain rules, there are a few exceptions where these rules might not apply. It is important to be aware of these exceptions to ensure clear and effective communication. Let’s explore some key exceptions along with brief explanations and examples for each case:

1. Contextual Ambiguity

In certain contexts, the use of “these” and “thesis” can be ambiguous, leading to potential confusion. In such cases, it is crucial to consider the specific meaning and intent of the sentence to determine the appropriate usage.

  • Incorrect: These ideas are central to the thesis.
  • Correct: These ideas are central to this thesis.

In the incorrect example, the use of “these” without clarifying the specific thesis creates ambiguity. By adding the article “this,” the sentence becomes clearer and more precise.

2. Technical Terminology

In technical or specialized fields, certain terms and phrases may require specific usage of “these” or “thesis” that deviates from the general rules. It is essential to consult field-specific guidelines or style manuals to ensure accurate usage.

  • Incorrect: The theses of these scholars provide valuable insights.
  • Correct: The theses of these scholars provide valuable insights.

In this example, the usage of “theses” instead of “thesis” might seem incorrect based on the general rules. However, in academic or research contexts, it is common to refer to multiple research papers or studies as “theses,” even though the singular form is “thesis.”

3. Idiomatic Expressions

Idiomatic expressions, which are phrases that have a figurative meaning different from their literal interpretation, may involve the use of “these” or “thesis” in unconventional ways. Familiarity with these expressions is key to understanding and using them correctly.

  • Incorrect: The thesis of the matter is quite complex.
  • Correct: The crux of the matter is quite complex.

In this instance, the idiom “the crux of the matter” is used instead of the literal interpretation of “the thesis of the matter.” Understanding idiomatic expressions helps avoid confusion and ensures accurate usage in such cases.

By being aware of these exceptions and understanding their proper usage, you can effectively navigate the intricacies of using “these” and “thesis” in various contexts. Remember to always consider the specific meaning and intent of your sentence, consult field-specific guidelines when necessary, and be familiar with idiomatic expressions to communicate with clarity and precision.

Understanding the distinction between “these” and “thesis” is crucial for effective communication and clear writing. While “these” refers to a plural form of the demonstrative pronoun, used to indicate specific objects or ideas in proximity, “thesis” pertains to a central argument or proposition in an academic or scholarly work.

Throughout this article, we have explored the nuances and applications of both terms, highlighting their unique roles in different contexts. By correctly utilizing “these,” writers can accurately refer to multiple objects or concepts, avoiding ambiguity and enhancing clarity in their writing.

On the other hand, a “thesis” forms the foundation of an academic paper, serving as a guiding principle and a focal point for the entire work. It encapsulates the main argument or hypothesis that the author aims to prove or explore in a systematic manner.

By recognizing the differences between “these” and “thesis,” writers can ensure precision in their language and effectively convey their intended meaning. Whether it is distinguishing between multiple objects or constructing a well-defined argument, mastering the usage of these terms will undoubtedly elevate the quality of one’s writing.

Sharing is caring!

Do you know the plural of thesis? Understanding the correct plural of thesis is important not only for academic writing, but for general communication as well. Whether you’re discussing multiple research papers or simply trying to sound knowledgeable in a conversation, using the correct plural form can help you make a good impression and avoid any confusion or misunderstandings.

Plural of Thesis

Plural of Thesis: A Quick Guide for English Learners

Definition and Plural of Thesis

When writing a research paper or dissertation, the central argument or main point is known as a thesis. A thesis is a statement or proposition that is put forward as a premise to be maintained or proved. It is a crucial element of academic writing and is often required for a degree or certification.

The plural of thesis is “theses.” In English, most nouns form the plural by adding an “s” at the end. However, “thesis” is one of the few exceptions to this rule. The word “thesis” has a Greek root, and “theses” is how it is pluralized in that original language.

Singular Plural
Thesis Theses

It is important to note that “theses” is the only way to make the noun “thesis” plural. There is no alternative form of the plural for this word.

In academic writing, the plural form “theses” is commonly used when referring to multiple research papers or dissertations. For example, “I have read several theses on this topic, and they all have different viewpoints.”

When to Use Thesis and Its Plural Form

When writing academic papers or conducting research, it is important to understand when to use the word “thesis” and its plural form, “theses.” Here are some guidelines to help you use these words correctly:

  • Use “thesis” when referring to a single research paper or dissertation that presents a specific argument or viewpoint.
  • Use “theses” when referring to multiple research papers or dissertations.
  • Remember that “thesis” is a singular noun and “theses” is its plural form.
  • Be aware that “thesis” has a Greek root and follows the same pluralization rule as other Greek words ending in “-is,” such as “crisis” and “analysis.” They become “crises” and “analyses,” respectively.
  • Keep in mind that “thesis” can also refer to a statement or proposition that is put forward for consideration or discussion. In this case, the plural form would be “theses.”
  • When citing multiple theses in a paper, use “theses” to indicate the plurality. For example, “The theses presented in this paper all support the idea that…”

Examples of Thesis and Its Plural Form in Sentences

If you are wondering how to use the word “thesis” in a sentence, here are a few examples:

  • Your thesis statement should be clear and concise.
  • The professor asked us to submit our theses by the end of the semester.
  • The thesis of the article is that climate change is caused by human activity.
  • She spent months researching and writing her thesis on the history of feminism .
  • The committee was impressed by the depth and originality of his thesis.

As you can see, “thesis” is used to refer to a statement or argument put forth by a writer or speaker, as well as a research paper written by a student to earn a degree.

Now, let’s take a look at the plural form of “thesis.” According to Grammar Monster, the only correct way to form the plural of “thesis” is “theses.” Here are some examples of how to use “theses” in a sentence:

  • The library has a collection of theses written by graduate students.
  • The professor asked us to read several theses on the topic before starting our own research.
  • The theses presented at the conference covered a wide range of topics.
  • The committee was impressed by the quality and originality of the theses submitted.

Plural Noun Rules for Regular Nouns

When forming the plural of regular nouns, there are some standard rules to follow. These rules apply to most English nouns, including “thesis.” Here are the basic guidelines:

  • For most singular nouns, simply add an “-s” to the end to form the plural. For example, “book” becomes “books,” “car” becomes “cars,” and “house” becomes “houses.”
  • If the singular noun ends in “-s,” “-x,” “-z,” “-ch,” or “-sh,” add “-es” to form the plural. For example, “bus” becomes “buses,” “box” becomes “boxes,” “buzz” becomes “buzzes,” “church” becomes “churches,” and “dish” becomes “dishes.”
  • If the singular noun ends in a consonant followed by “-y,” change the “-y” to “-ies” to form the plural. For example, “city” becomes “cities,” “baby” becomes “babies,” and “story” becomes “stories.”
  • If the singular noun ends in a vowel followed by “-y,” simply add an “-s” to form the plural. For example, “boy” becomes “boys,” “key” becomes “keys,” and “day” becomes “days.”

It’s important to note that there are some irregular nouns that don’t follow these rules. For example, “child” becomes “children,” “foot” becomes “feet,” and “tooth” becomes “teeth.” However, “thesis” is a regular noun, so it follows the standard rules for forming the plural.

Plural Noun Rules for Irregular Nouns

When it comes to forming the plural of nouns in English, there are some general rules that apply to most words. However, there are also many irregular nouns that don’t follow these rules and have unique plural forms. In this section, we’ll go over some common irregular plural nouns and the rules for forming their plurals.

List of Common Irregular Plural Nouns

Here are some examples of irregular plural nouns that you may come across:

Singular Plural
Child Children
Foot Feet
Goose Geese
Man Men
Mouse Mice
Tooth Teeth
Woman Women

Nouns that End in Us

Nouns that end in “us” often have a plural form that ends in “i”. For example:

Singular Plural
Cactus Cacti
Focus Foci
Radius Radii

Nouns that End in Is

Nouns that end in “is” may have a plural form that ends in “es”. For example:

Singular Plural
Analysis Analyses
Basis Bases
Crisis Crises

Nouns that End in On

Nouns that end in “on” may have a plural form that ends in “a”. For example:

Singular Plural
Criterion Criteria
Phenomenon Phenomena
Vertex Vertices

Plurals That Are the Same as Singulars

Some nouns have the same form for both the singular and plural. For example:

Singular Plural
Deer Deer
Fish Fish
Sheep Sheep

Words That Look Like Plural Nouns but Are Singular Nouns

Some words may look like plural nouns but are actually singular nouns. For example:

Singular Plural
News
Mathematics
Physics

Collective Nouns and List

When it comes to forming the plural of nouns, collective nouns can be a bit tricky. A collective noun refers to a group of people or things as a single entity. For example, “team” is a collective noun because it refers to a group of individuals working together towards a common goal.

The challenge with collective nouns is deciding whether to treat them as singular or plural. In American English, collective nouns are usually treated as singular, while in British English, they can be treated as either singular or plural depending on the context.

Here are some examples of collective nouns and how they can be treated in different contexts:

Collective Noun Singular Example Plural Example
audience The audience is enjoying the show. The audience are clapping their hands.
family My family is going on vacation. My family are all different ages.
staff The staff is working hard. The staff are taking their lunch breaks.

As you can see, the choice of whether to use a singular or plural verb depends on whether you are referring to the group as a single entity or as individuals within the group.

When it comes to forming the plural of collective nouns, the same rules apply as for regular nouns. For example, the plural of “team” is “teams”, and the plural of “family” is “families”.

Plural Nouns vs. Possessive Nouns

When it comes to forming the plural of nouns, there are standard rules that apply to most words in the English language. However, there are some exceptions, such as the word “thesis.” The plural of “thesis” is “theses,” and this is the only correct way to form the plural of this word.

On the other hand, when it comes to forming possessive nouns, there are a few rules to keep in mind. Here are some key points to remember:

  • For singular nouns, add an apostrophe and an “s” to show possession. For example, “the thesis’s conclusion” means the conclusion belonging to the thesis.
  • For plural nouns that end in “s,” add only an apostrophe to show possession. For example, “the theses’ conclusions” means the conclusions belonging to the theses.
  • For plural nouns that do not end in “s,” add an apostrophe and an “s” to show possession. For example, “women’s rights” means the rights belonging to women.

It’s important to note that possessive nouns should not be confused with plural nouns. While they may look similar, they serve different grammatical functions. Possessive nouns show ownership or possession, while plural nouns simply refer to more than one of something.

Common Mistakes with Plural Nouns

When it comes to forming the plural of nouns, there are some common mistakes that are made. Here are a few things to keep in mind when forming the plural of the word “thesis” and other nouns:

Adding an Apostrophe

One common mistake is adding an apostrophe to a noun to make it plural. For example, “the thesis’s” instead of “the theses.” This is incorrect and should be avoided.

Irregular Plurals

Some nouns have irregular plurals that do not follow the standard rules. For example, “child” becomes “children” and “goose” becomes “geese.” It is important to learn these irregular plurals to avoid mistakes.

Confusion over Plurals

Some nouns, like “thesis,” can cause confusion over their plural form. “Theses” is the only correct way to make “thesis” plural. Other words that end in “-is” may also have irregular plurals, such as “crisis” becoming “crises.”

Using Incorrect Count Nouns

It is important to use the correct count nouns when referring to multiple instances of something. For example, “studies” instead of “researches,” and “pieces of evidence” instead of “evidences.” Using the incorrect count noun can make your writing sound awkward or confusing.

The English word is a doublet of deed .

Sense 1.1 (“proposition or statement supported by arguments”) is adopted from antithesis . [ 2 ] Sense 1.4 (“initial stage of reasoning”) was first used by the German philosopher Johann Gottlieb Fichte (1762–1814), and later applied to the dialectical method of his countryman, the philosopher Georg Wilhelm Friedrich Hegel (1770–1831).

The plural form theses is borrowed from Latin thesēs , from Ancient Greek θέσεις ( théseis ) .

Dissertation vs. Thesis—What’s the Difference?

Matt Ellis

If you’re confused about the meaning of dissertation versus thesis , you’re not alone. These two types of academic writing have a lot in common, but their meanings are reversed in American and British English. Depending on where you are in the world, the differences between a dissertation and a thesis might change!

What is a dissertation vs. a thesis?

In American English, a dissertation is a research paper that’s required to earn a doctorate degree, while a thesis is a research paper required to earn a master’s degree. Dissertations and theses (the plural of thesis ) are often mixed up because they’re both lengthy research papers written for higher education, especially as part of a master’s or doctorate program. A thesis or dissertation is often a requirement for obtaining an academic degree, and both are usually seen as a gatekeeper for becoming eligible to graduate.

Informally the words dissertation and thesis are often used interchangeably, which only adds to the confusion. However, in the formal academic world, their meanings are different, although some universities occasionally have their own unique definitions. Let’s take a look at what dissertation and thesis actually mean.

What is a dissertation?

In American English, a dissertation is a highly involved research paper written as a requirement to earn a doctorate degree. When we say “highly involved,” we mean it; dissertations run 300 pages or more, essentially becoming a book-length research paper.

The central attribute of a dissertation is original research: To earn a doctorate, a person must submit new discoveries and data to their chosen field. This is symbolic of becoming part of a body of academic knowledge, and a systemic way to encourage the advancement of science.

In scientific fields of study, dissertations are empirical , drawing on data collected by the writer. In less-scientific fields, like literature or philosophy, dissertations are nonempirical : Instead of new data, “original research” is replaced by innovative new ideas, interpretations, analyses, or perspectives.

Dissertation may also involve what’s known as a dissertation defense , an oral presentation in front of a panel of experts, in addition to the paper. In a dissertation defense, the experts ask questions about the findings to test their validity, and the student must “defend” their research by explaining their methods and reasoning. The panel then decides whether or not the student graduates and earns their degree.

What is a thesis?

In American English, a thesis paper is a lengthy research paper written as a requirement to earn a master’s degree (or sometimes a bachelor’s degree, depending on the university). Also referred to as a “senior thesis” for undergraduate courses, these papers are written at the end of a program as a culmination of their studies, similar to dissertations.

Unlike a dissertation, a thesis doesn’t necessarily involve original research or ideas, although many master’s theses do. Generally, a thesis is less about adding to a body of knowledge, and more about testing a student’s skills in research, comprehension, or analysis. Regardless, a thesis paper is still a considerable amount of work and requires more effort than a standard academic paper.

Dissertation vs. thesis in American and British English

We’ve talked before about how British English and American English are different , and the definitions of dissertation versus thesis are just another example.

In short, the meanings are reversed: In British English, the term dissertation is used for bachelor’s and master’s programs, whereas thesis is used for doctorates. Keep in mind that academic institutions are very different in the US and the UK, not to mention in each individual English-speaking country, so what’s involved in a bachelor’s, master’s, and doctorate program is also different.

Do you need to write a thesis or dissertation?

It’s important to remember that the words dissertation and thesis are frequently used interchangeably, so the technical definitions are just for formal situations—like when submitting one or the other. If you’re confused, you can also ask your adviser. Each school or institution may have their own definitions of the terms.

Dissertation vs. thesis FAQ

What is a dissertation versus a thesis .

Dissertations and theses (the plural of thesis ) are often confused because they’re both lengthy research papers written for higher education. In American English, a dissertation is written to earn a doctorate whereas a thesis is written to earn a master’s (or sometimes a bachelor’s). In many informal situations, however, the terms dissertation and thesis are used interchangeably.

How do American and British English define dissertation versus thesis ?

In British English, the meanings of dissertation and thesis are reversed: A thesis is written to earn a doctorate, and a dissertation is written to earn a master’s or bachelor’s. Keep in mind that academic institutions are very different in the US and the UK, not to mention in each individual English-speaking country, so what’s involved in a bachelor’s, master’s, and doctorate program is also different.

When to use thesis or dissertation ?

It’s important to remember that the words dissertation and thesis are frequently used interchangeably, so the technical definitions are just for formal situations—like when submitting one or the other. If you’re confused, you can also ask your adviser; each school or institution may have their own definitions of the terms.
