What Is a Stanza?

In poetry, a stanza is used to describe the main building block of a poem. It is a unit of poetry composed of lines that relate to a similar thought or topic—like a paragraph in prose or a verse in a song. Every stanza in a poem has its own concept and serves a unique purpose. A stanza may be arranged according to rhyming patterns and meters—the syllabic beats of a line. It can also be a free-flowing verse that has no formal structure.
