The three main types of nonfiction are creative nonfiction, essay, and journalism.
Creative nonfiction is a type of writing that uses elements of both fiction and nonfiction. It often includes elements of personal narrative or memoir, but it can also include elements of research, interviews, and even fictional characters or scenarios.
The essay is another type of nonfiction that often uses elements of creative nonfiction, but it can also be more scholarly in nature. Essays can be personal or argumentative in nature, and they are often shorter than other types of nonfiction.
Journalism is a type of nonfiction writing that focuses on reporting and conveying information. This can be done through news articles, features, or even opinion pieces.
