A villanelle, also known as villanesque, is a nineteen-line poetic form consisting of five tercets followed by a quatrain. There are two refrains and two repeating rhymes, with the first and third lines of the first tercet repeated alternately at the end of each subsequent stanza until the last stanza, which includes both repeated lines. The villanelle is an example of a fixed verse form. The word derives from Latin, then Italian, and is related to the initial subject of the form being the pastoral.

Poetry, also called verse, is a form 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, a prosaic ostensible meaning. A poem is a literary composition, written by a poet, using this principle.
