Persuasive writing aims to convince the reader to adopt a particular viewpoint or course of action. It clearly communicates an opinion using language and persuasive devices that effectively sway the reader. Examples, comparisons, statistics, expert opinions, and repetition are effective persuasive devices. A strong persuasive essay introduces the position it advocates and outlines three main supporting points, argues each point in a separate body paragraph using persuasive devices, and concludes by summarizing the main arguments.
