How to Write a Expository Essay
The expository essay is actually one of the most straightforward assignments
you will ever encounter. Its purpose is simply to describe or explain a specific
topic to the reader using factual information.
You do not have to develop an argument or prove anything in an expository
essay; you only have to understand your topic and present it to the reader
in a logical, cogent manner.
An expository-writing prompt will ask you to describe the changes wrought
by the Industrial Revolution, but it will not require you to take a position
on whether the Industrial Revolution had a positive or negative impact..
Writing an expository essay
Usually, an expository essay is structured in five paragraphs. The first is the introduction, which contains the thesis statement. The next three body paragraphs each develop a separate point to support the thesis, and provide factual examples and information. The fifth and final paragraph is the conclusion, which ties the body paragraphs together and sums up the essay. Since the content is factual, you will need to write in the third person only. This means no "I" or "you" in the essay.
The thesis statement drives the structure and content of the expository essay.
It's the most important sentence in your essay, but that doesn't mean it has
to be complicated. In fact, the best thesis statements are simple. It's important
that the statement be clear and that it be one that you can support with facts.
A thesis statement for an expository essay should not express an opinion or
take a position on a topic.
Too much: The Boston Tea Party was the most important act
of civil disobedience in the American colony because it protested unjust taxation
without representation and was therefore the main cause of the Revolutionary
War.
Just right: 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.
A strong thesis for an expository essay will not present an opinion or state
an argument. Remember, your thesis statement should be based purely on factual
information that you present in the body of your essay. It should be clear,
concise, and well written. Once you have a sound thesis in place, writing
the rest of your essay will be easy because you will know exactly what information
you need to present.
