A couplet is a literary device that can be defined as having two successive rhyming lines in a verse, and has the same meter to form a complete thought. It is marked by a usual rhythm, rhyme scheme, and incorporation of specific utterances.
Here's a famous couplet: "Good night! Good night! Parting is such sweet sorrow / That I shall say good night till it be morrow." The couplet above comes from Shakespeare's Romeo and Juliet, which is a play, not a poem
