Literature can be broadly defined as anything that has ever been written. It comes in two main forms - prose and poetry. Prose is written in paragraph form using ordinary language to convey ideas, while poetry uses meter, rhythm and figurative language. Studying literature is important as it allows us to better understand human nature, society, and ourselves by exploring themes in writings that reflect the thoughts and emotions of their time. The document then provides examples of different genres and forms within prose and poetry.
