Persuasive writing is the main style of writing you will use in academic papers. When an author writes in a persuasive style, he or she is trying to convince the audience of a position or belief. Persuasive writing contains the author’s opinions and biases, as well as justifications and reasons given by the author as evidence of the correctness of their position. Any “argumentative” essay you write in school will be in the persuasive style of writing.
Examples of expository writing include:
Critiques or Reviews of articles/events
Letters to the editor
