Overview

Writing that explains and informs is called exposition. An expository essay consists of an introduction that includes a thesis statement, a body of details that support the thesis, and a conclusion that states the implications of the thesis.

When you explain a process, be sure to clearly show one step at a time. To describe a cause-and-effect relationship, show that one event or fact causes another. In a comparison-contrast paper, you explain how two or more subjects are similar and how they are different. Categorize a word or subject in order to define it effectively. Write a problem-and-solution paper to examine a complex problem and explore its possible solutions.

Graphics often provide additional clarification of a topic. You can use a line graph, a bar graph, or a pie chart to illustrate your thesis. A Venn diagram or a comparison frame is useful when you are prewriting a comparison-contrast essay.

Because the primary purpose of a news story is to inform, you should present the most important information first. Start with a lead, an attention-grabbing opening paragraph that sums up the most important event. Then relate other events in decreasing order of importance.

Understanding exposition is helpful when answering an essay question on an exam. Plan how to answer the question, estimating how much time you will need. The more important the question is to your score on the exam, the more time you should devote to answering the question. You can also apply your knowledge of expository writing when you analyze literature.
