The expository essay writing should have the same basic elements and structure as any typical paper. The main elements of the expository paper are the introduction, body and the conclusion. A basic expository essay writing document will contain at least 5 paragraphs, 3 of which are the main points that explain, describe or analyze the topic. The length of the expository paper will be determined by its topic, content and degree of specialization or specific technology.
The expository introductory paragraph contains the purpose or topic and introduces the key points or sub-topics that will be examined. Generally the topic is chosen in response to a prompt that asks the reader to explain events, processes, or analyze ideas, history, written works or political developments to name a few examples. Expository essay writing uses facts to support the thesis rather than opinions and takes the information directly from research to focus on the thesis.
The expository body of the thesis offers main points or sub-topics to further define the topic and information. All the information presented is used to narrowly focus the topic and to clarify all aspects of the thesis. Each paragraph using expository style should have one predominant point that directly supports the thesis. All the information in that expository paragraph should relate directly to the main point and the information should be complete and factual.
