What does the term 'stanza' refer to in poetry?

The term 'stanza' refers to a section of a poem, typically composed of a specific number of lines grouped together. Stanzas function much like paragraphs in prose, organizing thoughts or themes within the poem while contributing to its overall structure and rhythm. By breaking the poem into sections, stanzas help to enhance its readability and emotional impact, allowing the poet to convey ideas more clearly across distinct parts. The other options focus on singular lines, themes, or poetic devices, which do not encapsulate the broader idea of a stanza as a grouping of lines that form a cohesive part of the poem.
