What is prose fiction?

Prose fiction is any form of fictional storytelling that is written in prose (as opposed to verse, which is poetry). This means it uses ordinary grammatical structure rather than metrical structure. Examples include:

* Novels: Long-form prose fiction narratives.

* Novellas: Shorter than novels, but longer than short stories.

* Short stories: Brief, self-contained narratives.

* Flash fiction: Extremely short stories, often only a few paragraphs or even sentences long.

Essentially, if it's a made-up story told in regular sentence and paragraph form, it's prose fiction.
