II. Guidance for Expository Writing
1. Definition of Expository Writing
• Expository essays require that the writer give information, explain the topic or define something. They are best developed by the use of facts and statistical information, cause and effect relationships or examples. • Since they are factual, they are written without emotion and usually in the third person. The use of the pronoun “I” is not usually found in this form of essay.
