Expository Writing: Definition and Examples

What is expository writing, what is an expository paragraph, expository writing examples, how prowritingaid can help you with expository composition.

One of the most common types of writing is expository writing. Whether you’re a student taking an English class or a professional trying to communicate to others in your field, you’ll need to use expository writing in your day-to-day work.

So, what exactly does this term mean?

The short answer is that expository writing refers to any writing designed primarily to explain or instruct.

Read on to learn the definition of expository writing as well as some examples of what this type of writing can look like.

Before we look at examples of expository writing, let’s start with a quick definition of what this term actually means.

Expository Writing Definition

The term expository writing refers to any writing that’s designed to explain something. We use the word expository to describe any passage of writing that’s supposed to present information and help you understand it in an objective way.

Some common examples of expository writing include academic essays, textbooks, instructional guides, and news reports. Good expository writing should be factual, objective, and clear.

To better understand what this term means, think about the difference between a scientific article, a short story, and an advertisement.

The scientific article is considered expository writing because its primary purpose is to explain a particular topic in more detail. It presents data, analyzes what that data means, and focuses on the facts.

On the other hand, the short story isn’t considered expository writing, because its core purpose isn’t to explain or inform—instead, it’s probably trying to entertain you or to take you on a journey. Short stories are narrative writing.

Similarly, an advertisement isn’t expository writing because its core purpose isn’t to explain or inform—instead, it’s trying to persuade you to buy what it’s selling. Advertisements are persuasive writing.

Here’s a quick rundown of what expository essays should and shouldn’t do.

An expository essay should:

Teach the reader about a particular topic

Focus on the facts

Follow a clearly organized structure

Present information and details from credible sources

An expository essay should not:

Try to change the reader’s mind about something

Present the author’s personal opinions

Include made-up narratives or stories

Follow experimental or nonlinear structures

An expository paragraph is exactly what it sounds like—a paragraph of expository writing.

A well-written expository paragraph should follow a specific format to make it as clear and easy to read as possible. Most expository paragraphs do the following things:

Start with a topic sentence, which explains what the paragraph will be about

Then, include 3 – 5 body sentences that provide supporting details for the topic sentence

Finally, wrap things up with a closing sentence that summarizes what the paragraph has said

Writing an expository paragraph is a great way to practice expository writing. That’s because the paragraph follows the same structure as a more complex expository essay, just on a smaller scale.

Most expository essays should follow this format:

Start with an introductory paragraph that includes the thesis statement, which tells the reader the core statement of the essay

Then, include 3 – 5 body paragraphs that provide factual evidence to support the thesis statement

Finally, wrap things up with a concluding paragraph that summarizes what the body paragraphs and thesis statement said

You can see the similarities between the two formats. If you can write a fantastic expository paragraph, you’ll be well-prepared to move on to writing a full expository essay.

Example of Expository Paragraph

Here’s an example of an expository paragraph that follows the structure described above.

The leading cause of death in the United States is heart disease, which can be fatal if it leads to heart attack or cardiac arrest. Heart attacks occur when a blockage in the coronary artery prevents oxygenated blood from reaching the heart. Cardiac arrests occur when the heart stops pumping entirely, which prevents the patient from breathing normally. Both of these problems can be deadly, even in seemingly healthy people who don’t have noticeable risk factors. As a result, heart disease is an important problem that many doctors and scientists are researching.

Good writing = better grades

ProWritingAid will help you improve the style, strength, and clarity of all your assignments.

There are many ways you can present information in an expository essay. Here are four of the most popular ways, along with examples of each one.

Problem and Solution Essay

A problem and solution essay presents the reader with a problem and then considers possible solutions to that problem.

Here’s an example passage you might find in a problem and solution essay:

Among the many proposed solutions to rising carbon emissions, one promising possibility is carbon trapping. Scientists are figuring out how to pull carbon emissions out of the atmosphere and trap it in less harmful forms, such as by injecting carbon dioxide underground so it will turn to stone.

Compare and Contrast Essay

This type of essay takes two subjects and compares and contrasts them. It focuses on highlighting the differences and similarities between those two things.

Here’s an example passage of this type of expository writing:

Though country music and R&B music have very different sounds, they also share many similarities. For one thing, both types of music embody a specific cultural identity. For another, both genres trace their roots back to the 1920s, when the Victor Talking Machine Company signed singers from the American South.

Classification Essay

In a classification essay, you describe the categories within a certain group of things.

Here’s an example passage you might find in a classification essay:

There are three ways in which artificial intelligence might become stronger than humans in the future: high speed, high collective intelligence, and high quality. A speed AI would be able to perform calculations and experience the world much faster than humans. A collective intelligence, like a hive mind, would be able to break down a complex task into several parts and pursue them simultaneously. Finally, a quality AI would simply be able to solve more complex problems than humans could.

Process Essay

In a process essay, you give the reader the steps for completing a specific process. This is similar to a how-to guide or an instruction manual.

Here’s an example passage you might find in this type of expository writing:

Caramelize the chopped onions in a frying pan. When the onions have caramelized, mix in the bell peppers, mushrooms, and tomatoes and stir for 4 – 6 minutes or until all the ingredients have softened. If you want to add meat, you can add ground beef and cook for another 4 – 6 minutes. Season with salt and pepper to taste.

Good expository writing should be easy to read. After all, the purpose of exposition is to explain things to your readers, and you won’t be able to accomplish that if they have trouble understanding your writing.

That’s why ProWritingAid can help you write an expository essay. The grammar checker can help you ensure your sentences flow well, you’re not missing any necessary punctuation, and all your words are precise and clear.

Good luck, and happy writing!

How to Write an Expository Essay

Published by Grace Graffin at August 17th, 2021 , Revised On July 26, 2023

Expository means “to describe or explain something” . It is related to the words ‘exposition’, ‘expound’, and ‘expose’ – to explain or reveal the meaning, to lay open, speak one’s mind.

Whenever there is a need to gather research and describe an idea, a topic , or a process clearly and logically, it is done in the form of an expository essay .

An expository essay requires the writer to take a balanced approach to the subject matter rather than justifying a particular point of view.

Expository essays are assigned to students to evaluate their subject knowledge and composition skills. When compared with argumentative essays , they involve a lot less research.

Definition of Expository Essay

“The expository essay is the type of essay that involves an investigation of an idea or topic, appraises relevant supporting evidence material, and presents an argument in a clear and concise manner. ”

When to Write an Expository Essay

Your school or university could assign an expository essay to you as coursework or as part of an online exam.

However, the guidelines may or may not clearly state that your assignment is an expository essay. If that is the case, then look for keywords like ‘explain’, ‘describe’, ‘define’, etc., to be sure that what has been asked for is an expository essay.

You might even be asked to explain and emphasise a particular concept or term. Writing a simple definition will not be enough because you will be expected to explore the ideas in detail.

Writing an Expository Essay

An expository essay should not be based on your personal experiences and opinions. It rather takes an objective approach. You will be expected to explain the topic in a balanced way without any personal bias.

Make sure to avoid the first and second person (“I” and “You”) when writing an expository essay.

How to Structure an Expository Essay

The structure and format of your expository essay assignment will depend on your school’s guidelines and the topic you are investigating. However, it is always a good idea to develop an outline for your essay before starting to work.

The Five-Paragraph Essay Writing Approach

An expository essay will require you to take the five-paragraph essay approach: an introductory paragraph , a main body paragraph , and a concluding paragraph . This is often referred to as the hamburger style of the essay because, like a hamburger, it contains five main parts: the introduction and conclusion being the bun that encapsulates everything.

Rationale and Thesis Statement

Start your essay with a rationale and thesis, also known as the thesis statement , so your readers know what you set out to achieve in your expository essay assignment. Ensure the thesis statement is narrow enough to follow the guidelines in the assignment brief. If the thesis statement is weak and too broad, you will struggle to produce a flawless expository essay.

The Framework

Construct a framework, so you know what elements will constitute the basis of your essay.

Expository Essay Introduction

Like other essay types , an expository essay begins with an introduction , including a hook, background to the topic, and a thesis statement. Once you have grabbed the readers’ interest, it will be easier to get them to read the remaining essay.

Frequently Asked Questions

Will i need the skill of expository writing after i finish my studies.

It depends on what you are studying for. While you might or might not write any more expository essays after your formal education has ended, the skill will be very useful in certain careers, such as business reports, journalism, and in scientific and technical writing.

How does an expository essay differ from an argumentative essay?

An argumentative essay is usually longer and requires more research. It starts with a claim about something that will need supporting evidence. And both sides of the argument need to be discussed. In an expository essay, there is no requirement to make an original argument and defend/support it.

What is the purpose of expository essays?

This style of essay is necessary when you have to showcase your knowledge on a given subject, or your ability to gather research on one and present your findings.

How long is an expository essay?

There is no fixed length but an expository essay could be part of an exam, in which case it might only be 1,000 words or less. They are usually shorter than argumentative essays . It can depend on the subject under discussion. You will likely be given instructions on the required word count.

Are there different types of expository essay?

There are six different types of expository essay, each with a different purpose.

The six types are:

Process essay – describing a task, a method, how to complete something Cause and effect essay – why something happened and its effects Problem-solution essay – provide analysis of problems and their solutions Compare and contrast essay – describe the similarities and differences between two subjects Definition essay – define the topic in detail and explain the how, what, and why Classification essay – separate the topic’s categories and define them in detail

When you are assigned your essay, you should be able to distinguish which of these approaches you are required to take.
