A couplet is formed by two rhymed lines of poetry. A rhymed couplet is a pair of successive lines that rhyme and have the same meter, which means that they have the same rhythmic pattern or length. The couplet is often used as a complete thought or to provide a punchline to a poem. Shakespearean sonnets typically end with a rhymed couplet, which serves as a conclusion or summary of the poem.
