Expository writing, or exposition, is a type of discourse used to describe, explain, define, inform, or clarify.It literally means "to expose." Exposition can be found in writing or oral discourse, but for the sake of this article, we'll stick with expository writing.
As the main aim of the expository essay is to explain a topic in a logical manner, the topics must contain signal words that illustrate this action.
The first is to keep a tight focus on the main topic, avoiding lengthy tangents, wordiness, or unrelated asides that aren’t necessary for understanding your topic.
In the same vein, be sure to pick a topic that is narrow, but not so narrow that you have a hard time writing anything about it (for example, writing about ice cream would be too broad, but writing about ice cream sold at your local grocery store between and pm last Saturday would be too narrow).
The aim of the argumentative essay is to expand the information on the topic in a logical manner.
The essay writer must support his ideas with relevant evidence.
