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).
You are likely familiar with expository writing already, even if the name sounds unfamiliar.
Common examples include newspaper articles, how-to manuals, and assembly instructions.
In college, teachers practice to assign them different types of an essay to train their writing skills.
But they continue to confuse such elementary things as “narrative” and “expository” essay.
Good expository essay topics usually start with words “Describe”, “Explain”, “Define”.
They show the writer the aim of the text he is going to write.
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.
