Have you just been asked to write an expository essay? Don’t be intimidated! The name comes from the same root as “exposure,” and it’s just a fancy label that means you’ve been asked to explain something. In fact, whether you’ve been asked to write an academic essay or prepare a persuasive speech, they both involve the same procedure. Basically, you’re writing about a theme or topic, choosing your main take or angle on it, analysing evidence, and then explaining it. And the easiest way to practice is by writing a five-paragraph essay.
