Prose fiction is imaginative literature that is not intended to be factually true or false. It uses invented characters, dialogue, narration, and description. There are different types based on length and complexity, including short stories, novellas, and novels. A short story is typically around 2,000 words and focuses on a single effect or episode through few characters, incidents, scenes, and settings. Experts note that short stories require extreme economy of words and focus, with no excess words unrelated to the central story or theme.
