n.
Two successive lines of verse.
A couplet is marked usually by rhythmic correspondence, rhyme, or the inclusion of a self-contained utterance. Couplets may be independent poems, but they usually function as parts of other verse forms, such as the Shakespearean sonnet , which concludes with a couplet. A couplet that cannot stand alone is an open couplet; a couplet whose sense is relatively independent is a closed couplet.
