Stanza
In poetry, a stanza is a unit within a larger poem. In modern poetry, the term is often equivalent with strophe; in popular vocal music, a stanza is typically referred to as a "verse" (distinct from the refrain, or "chorus").
A stanza consists of a grouping of two or more lines, set off by a space, that usually has a set pattern of meter and rhyme.
The stanza in poetry is analogous with the paragraph that is seen in prose, related thoughts are grouped into units.
In traditional English-language poems, stanzas can be identified and grouped together because they share a rhyme scheme or a fixed number of lines (as in distich/couplet, tercet, quatrain, cinquain/quintain, sestet).
In much modern poetry, stanzas may be arbitrarily presented on the printed page because of publishing conventions that employ such features as white space or punctuation.
