World literature refers to learning about the values, cultures, attitudes, thoughts, beliefs and experiences represented in the poetry, prose, and other creative works of different continents around the world. Literature comes in many genres, including poetry, prose, fiction and nonfiction. Poetry is written in verse with measures, rhymes and lines that aim to both delight and instruct readers. Prose follows basic grammatical structures and includes fiction like novels and short stories, as well as nonfiction forms. Fiction uses imaginative elements to present truths about human life, while nonfiction is based mainly on facts.
