A poet is someone who writes poetry, or a poem. Poetry is a type of literature that uses aesthetic and often rhythmic qualities of language—such as phonaesthetics, sound symbolism, and metre—to evoke meanings in addition to, or in place of, the prosaic ostensible meaning. Poetry has a very long history, dating back to prehistorical times with the creation of hunting poetry in Africa, and panegyric and elegiac court poetry was developed extensively throughout the history of the empires of China and India. Ancient Greek attempts to define poetry, such as Aristotle’s Poetics, focused on the uses of speech in rhetoric, drama, song and comedy. Later attempts concentrated on features such as repetition, verse form and rhyme, and emphasized the aesthetics which distinguish poetry from more objectively informative, prosaic forms of writing. From the mid-20th century, poetry has sometimes been more generally regarded as a creative act employing language.

Poetry often uses particular forms and conventions to expand the literal meaning of the words, or to evoke emotional or sensual responses. Devices such as assonance, alliteration, onomatopoeia and rhythm are sometimes used to achieve musical or incantatory effects. The use of ambiguity, symbolism, irony and other stylistic elements of poetic diction often leaves a poem open to multiple interpretations. Similarly, figures of speech such as metaphor, simile and metonymy create a resonance between otherwise disparate images—a layering of meanings, forming connections previously not perceived. Kindred forms of resonance may exist, between individual verses, in their patterns of rhyme or rhythm.

Some poetry types are specific to particular cultures and genres and respond to characteristics of the language in which the poet writes. Much modern poetry reflects a critique of poetic tradition, playing with and testing, among other things, the principle of euphony itself, sometimes altogether forgoing rhyme or set rhythm. In today’s increasingly globalized world, poets often adapt forms, styles and techniques from diverse cultures and languages.
