Literature can be divided into four major classifications: poetry, prose, fiction, and non-fiction. It exists in oral, written, and visual forms and includes various genres such as narratives, lyrics, dramas, novels, biographies and more. Prose is the most common form of language and includes fiction like fairytales and myths, as well as non-fiction genres. Poetry uses aesthetic language and includes narrative poems, lyrics, and dramatic works. Literature provides entertainment and insight into human experiences through these diverse forms and classifications.
