Poetry is a form of literature that uses specific forms to express ideas and feelings through language. It has a speaker that narrates the poem, though this may not be the writer. A theme is the main idea or statement about life that a work tries to convey. Prosody is the study of meter, rhythm, and intonation in a poem. Meter and rhythm create patterns of stressed and unstressed syllables. Poems are organized into stanzas separated by spaces between lines. Figurative language such as similes, metaphors, personification, and onomatopoeia are commonly used in poetry.
