You write an expository essay to tell or teach the reader about a topic. Start by choosing a topic that you think is interesting and that you already know a lot about. You might choose to write about an animal you like, a place you have visited or a person whom you have read about. If you have too many ideas, make a list and then close your eyes and pick.
While expository is just a synonym for information, strict guidelines of the expository essay ensure that the information it contains is clear and concise. An easy way to get off on the right foot in writing an expository essay is to remember that the root of expository is expose. The writer's job is to totally expose the topic in a way that makes the information unmistakably clear to his/her audience.
