A couplet or distich is a poem or a stanza within a poem which contains two lines of matched verse in succession. They can be matched in length, in rhyme, or both. The shortest couplet that forms a poem is perhaps "Lines on the Antiquity of Microbes" by Strickland Gillilan:
- Had 'em.
- At least try
- To try
A couplet is also a pair of rhyming lines within a longer stanza.
