A couplet can be defined as,

“Two successive lines of verse forming a unit marked usually by rhythmic correspondence, rhyme, length or the inclusion of a self-contained utterance”.


“A unit of verse consisting of two successive lines, usually rhyming and having the same meter and often forming a complete thought or syntactic unit”.

Rhyming Couplets

Where a couplet is a pair of lines of verse where the end words might or might not rhyme, a rhyming couplet is when the last word of each of these lines exactly rhymes.
