Poem

Poetry (from the Greek word poiesis, "making") is a form of literary art that uses aesthetic and often rhythmic qualities of language to evoke meanings in addition to, or in place of, literal or surface-level meanings. Any particular instance of poetry is called a poem and is written by a poet. Poets use a variety of techniques called poetic devices, such as assonance, alliteration, euphony and cacophony, onomatopoeia, rhythm (via metre), and sound symbolism, to produce musical or other artistic effects. Most written poems are formatted in verse: a series or stack of lines on a page, which follow a rhythmic or other deliberate structure. For this reason, verse has also become a synonym (a metonym) for poetry.
