What is an expository essay?

According to the dictionary, expository means “serving to expound or set forth”. When the word first appeared in England in the 15th century, it meant a commentary on a particular subject.

A few words in the same category are “informative, instructive, didactic, and descriptive”.

As you can already imagine, an expository essay is a piece of writing where you talk at length about an important idea, present evidence and build an argument about that idea in clear, impartial, and easily understandable way.

Characteristics of an expository essay

It explains or informs the reader about:

  • how to do something
  • why something happened
  • how something works
  • why something should be done
  • or what something is

 

Moreover:

  • It’s written from the third person’s perspective (using “it” “he” “she” “they”)
  • It’s not about your personal opinion. Rather, it’s about informing the reader in an objective, non-biased manner by providing facts, examples, graphs, descriptive details, charts, and statistics.
  • It’s written in a formal style (but this depends on your target audience)
  • It’s written in a serious tone (no colloquialisms).

A few sample topics:

  • What does it take to become an Olympic athlete?
  • What are the temperamental differences between democrats and republicans?
  • How does a laser work?
  • What kind of a role diet plays in the weight loss process?

Expository Essays – 7 Most Frequently Asked Questions

1. How should you format your essay?

An expository essay usually consists of five paragraphs:

Introduction (1 paragraph)

What’s the purpose of this part?

  • Grab the attention of the reader.
  • Give a brief introduction to the topic.
  • Present to topic sentence (thesis) in a clear and concise manner.
  • Quickly present the main ideas you will share in the body of your essay.

 

The body of the essay (3 paragraphs)

What’s the purpose of this part?

  • Start each paragraph with a topic sentence where you tell your reader about the “first big idea”. After that, you provide supporting evidence for this idea.
  • In the next paragraph, you present the “second big idea” plus the supporting evidence, and then you repeat the same pattern in the third paragraph.
  • Each of these body paragraphs needs to be tightly related to the overall thesis.
  • Give reasons, arguments, and specific examples in support of your thesis.
  • Make sure that your essay flows smoothly by including a transition sentence at the beginning of each new paragraph.
  • Note: If you’re writing a longer essay, you’ll usually expand the body section by adding one or two more paragraphs.

 

Conclusion (1 paragraph)

What’s the purpose of this part?

  • Sum up what you’ve said in the last three paragraphs (but do it in an original way, using different vocabulary).
  • Restate your thesis.
  • End with a bang (try to evoke an emotional response in the reader).

 

Here’s a quick graph that will show you which structure to use:

expository essay format example

I also wrote a whole article about how to structure your essay.

2. Can you start your essay with a question?

It’s possible, but not recommendable. Starting your essay with a question looks too informal (especially if it’s a rhetorical one).

It’s much better to get straight to the point and address the issue which you’ll discuss in your essay.

3. How long should your essay be?

The length of your essay depends on your assignment and the level of your education. Between primary school and high school, essays can usually fit into a single A4 page.

If you’re applying to a university, you’ll have to write a 650-word long essay which is just a bit more than one A4 page.

If you study liberal arts at a university, you may be asked to write an essay that’s a couple of pages long. Then you would add more paragraphs to the body of your work.

Sometimes your professors will give you a range (for example – between 500 – 550 words). Always do your best to stay within that range.

But regardless of length, the format stays roughly the same and is comprised of three parts: introduction, body, and conclusion.

4. How is an expository essay different from a persuasive, argumentative or an analytical one?

In the expository essay, you talk at length about a specific subject. The main purpose is to provide as much relevant information as possible in an objective manner.

Argumentative (or persuasive) essay is different because as the name suggests, its purpose is to change the mind of the reader and persuade them to change their mind and start taking different types of action.

An analytical essay, on the other hand, it about analyzing, critiquing, and interpreting a specific event, painting, poem, song or a work of art. It’s narrower in scope than the expository one.

5. Can your essay be written from the first person’s point of view?

Not really. Expository work is a bit more serious so you should avoid saying “I” or “you”. Your job is to be an objective judge, presenting well-constructed evidence in support of your thesis.

Use the third person’s perspective when providing information (he, she, it, they).

6. What kind of tone and style should you use?

Most of the time you should use a more formal and serious style of writing. You’re discussing weighty matters with the reader and this calls for grace and equilibrium.

But it also depends on the audience you’re addressing. If you’re writing for young readers, you could choose a more informal approach.

7. How can I find sources to cite in my essays?

You need to find the best sources available on the topic and let them support your thesis.

Make sure that the sources you use (articles, books, academic research, historical documents) are fully legit. You don’t want to be quoting any unreliable texts.

Before including a source, be sure about:

  • Author’s credentials
  • Publisher’s reputation
  • The number of sources and citations the author includes in her work
  • Political bias (hidden agenda) – make sure your source is objective
  • The date of publication – make sure your source is not outdated

 

5 Different types of expository essays:

There are five main sub-categories of expository essays. Before starting to write your assignment, make sure you know which one are you going to focus on (if not sure, consult your teacher or professor).

5 Types of Expository Essays

Process essay – this is a “how to” type of essay. In it, you describe a step-by-step process of accomplishing a certain task. The goal here is to instruct the reader how to do something.

Topic example: How to prepare for a job interview.

Cause and effect essay – this type of writing is about interrelated occurrences that depend on each other. One of them (cause) has a direct (or non-direct) effect on the other.

The goal here is to describe this causal relationship in detail and determine the extent of the correlation. This type of essay is scientific in nature.

Topic example: The effect of a vegan diet on blood sugar level in adult women.

Compare and contrast essay – as the name suggests, this one is about comparing two (or more) different things, people, events or works of art. Your job is to show the similarities and talk about differences.

Topic example: The philosophical differences between Carl Jung and Sigmund Freud.

Classification essay – it’s about breaking down a specific subject into smaller categories or groups. The idea is to go from the more general to the more specific.

For example, you could describe computer languages as a whole, and then talk about different branches of coding such as HTML or C++.

Topic example: The evolution of different types of computer languages.

Definition essay – this type of essay deals with the meaning of a word, a concept, or a term. You may define something concrete (such as fortress), but most probably, you’ll have to wrestle with concepts of abstract nature (such as love or hate).

You will need to provide the formal definition and talk about context and connotations of the word.

Topic example: Definitions of love across the centuries.

Tips for the writing process: how to write your essay from start to finish

1. Start with your thesis

Your thesis statement is the most important sentence in your essay.

Unlike in other types of essays, in expository work, you don’t have to argue for anything or prove anything. Your job is to provide valuable information in a clear and succinct manner.

  • Don’t make extraordinary claims.
  • Don’t argue.
  • Don’t try to prove anything.
  • Don’t share your opinion.

Focus on facts and be an unbiased judge.

Remember that once you have your thesis in place, it will determine the scope of your essay.

How to craft a thesis:

a) You may have a writing prompt from your teacher. If that’s the case, do your best to follow it.
b) If you have to develop your own topic, define it carefully and make sure it’s narrow enough to fit into five paragraphs.
c) Do research and take notes. Before you start, research the subject a bit to make sure you’re attacking it from the right angle.
d) Boil your research down into a singular topic you want to address. This will be your thesis.

Here are a few examples of solid thesis statements (note how objective, narrow and neutral they are):

The development of the assembly line at the beginning of the XX century was one of the factors, which helped the USA to become a superpower.

Regular cardiovascular exercise diminishes the risk of heart attack among elderly people.

The social media channels like Facebook or Twitter lead to addictive behaviors in adolescents.

The Boston Tea Party was a significant act of civil disobedience that galvanized Americans around the issue of taxation without representation and helped
spark the Revolutionary War.

For more information on the topic of a thesis, please watch the video below or read this article.

2. Compile good notes and resources

The more research you do in the beginning, the better your essay will be at the end.

Gather as much information as possible. In fact, have more than you need so then you can use it strategically throughout your body paragraphs.

Your resources may consist of:

  • Anecdotes
  • Comparisons
  • Quotations
  • Statistics
  • Descriptive details
  • Definitions
  • Charts and graphs

Remember, your essay is didactic and scientific in nature so provide as much evidence and hard facts as possible.

3. Organize an outline for your essay

You already know that your essay needs to be formatted in a certain way and that it needs to be five paragraphs long.

But you also need to organize your ideas in a logical way. That’s where the outline comes in.

  • What are you going to write about first?
  • What’s coming after that?
  • Which statistics and quotes you want to include, and where?
  • What supporting evidence will you provide for your main ideas?

Jot down a simple plan on a piece of paper before you start writing.

You can learn more about outlining your essay by watching this video:

4. Write your first draft

Now it’s time to fill out your outline with great language, high-style, and lots of supporting evidence.

Write according to the format and specifications described above (and perhaps, provided by your teacher).

Don’t focus on grammar, spelling or punctuation yet. Just get your ideas down on paper or screen. The editing part comes later.

5. Revise and polish your draft

After you wrestle the first draft down to paper, give it a bit of room to breathe. Leave it alone for a few minutes or a few hours.

When you come back to it, you’ll be able to see it more objectively.

Then you can sit down and take care of language, punctuation, syntax, vocabulary, grammar and all the little details that make for a solid piece of writing.

6. Finish strong with a conclusion and restate your thesis

After you state your thesis, give a brief introduction, and present your ideas in the body paragraphs, it’s time to sum everything up.

The job of the concluding paragraph is to reaffirm your thesis in an original way (so you don’t repeat your self) and finish the essay to make a strong impression on the reader.

Maybe you won’t be able to leave your audience with jaws open like at the end of an epic movie, but ideally, that’s what you should strive for.
