If you search the Internet for a definition of an expository essay, you might become confused. Some books and websites define them as "how to" essays, while others give a long and confusing definition that seems to include every possible essay type out there.
Expository essays are simply essays that explain something with facts, as opposed to opinion. Sample styles include:
- Papers that described how to do something.
- Papers that analyze events, ideas, objects, or written works.
- Papers that describe a process.
- Papers that explain/describe an historical event.
- Explain the events leading up to the Revolutionary War.
- Explain how to balance a checkbook.
- Describe the composition and function of a chicken's egg.
The introductory paragraph will contain the thesis sentence, and the topic of the thesis should be grounded in fact.
