The document discusses literal and figurative language. Literal language means exactly what is said, while figurative language uses words or phrases in a non-literal way to imply a meaning. Figurative language is commonly found in poetry and can take various forms such as similes, metaphors, personification and more. It serves to make language more interesting by not always meaning what is literally said or read. Various figures of speech, sounds, and rhetorical devices are also described.
