essay will be one of the major preoccupations of your college or university program. While the
format for this kind of essay varies from one school to the next, the basic elements remain the
same. When I was preparing for my Ph.D. at Harvard University, I had no problem following

In teaching students how to write an expository essay, I always stress that the opening
paragraph is the most important part. In academic writing, it is crucial to make your first
paragraph concise and precise. It should simply explain who you are, what your research project
is about, and then briefly describe the main points you are trying to make in your work. If you
can tie your introduction into your main point, you will have better success in your writing.
Your second paragraph should include your thesis statement. This will summarize your entire
argument, including the supporting evidence and support for your claims. You should write this
paragraph before you begin to write the other four basic paragraphs of your how to write an
expository essay. However, you may wish to revise this paragraph after you have completed
The third paragraph should describe your main findings, using appropriate language (it is helpful
to use descriptive terms if possible). For example, if you are analyzing a set of data from NASA,

also help you to better describe your results, especially if you are writing for an audience of
Your fourth paragraph should end with a brief summary of your conclusion. In addition to
summarizing your arguments, your conclusion should tell your readers why they should read
your expository essay, and what they should expect to find within it. For example, if you are
writing about space travel, you might conclude that space travel is possible. In your conclusion,
you can recommend various routes for them to take, talk about what your research has found,
and tell your readers how to get started in exploring these routes themselves.
Your introduction should immediately grab the attention of your readers. In your introduction you
should introduce yourself, give some background information, tell a bit about your research, and
then discuss your topic in a clear and concise manner. Your introduction is important, because it
will allow your reader to know what kind of information you are going to present within your
paper. It will also help to give your readers ideas about what they can do while reading your
paper, as well as what kind of conclusions they should draw. This means including a clear
opening sentence, a thesis statement, and a body sentence.
The body is the meat of your essay. In your body you should include at least three main points,
all of which discuss different aspects of your topic. These points should not be overly involved,
and you should use as much personal experience and observation as possible to support each
of your main arguments. Your thesis statement is perhaps the most important part of your body,
and it will need to be carefully written and supported by your supporting facts and statements.
You should end each paragraph with a summarize of your points, as well as a
recommendation. Your summary will let your readers know what you think they should be aware of, and you can recommend various ways to learn more about your topic. You should also try
and end each paragraph with a final thought, and this is where you should put your name and

an expository essay can be very easy if you just remember these tips.
