A quatrain is best defined as a stanza of four lines. It is a common form in poetry and can have various rhyme schemes, such as AABB, ABBA, AABA, and ABCB. Quatrains are used in different types of poems, including sonnets, which traditionally consist of three quatrains followed by a final couplet. The term is part of a nomenclature that classifies stanzas by the number of lines they contain, similar to couplets (two lines), tercets (three lines), and so on. Quatrains can be a standalone poem or part of a larger piece and provide structure by grouping thoughts, themes, and ideas into manageable sections within a poem.
