Answer:
A couplet is two consecutive rhyming lines.
Step-by-step explanation:
Couplets illustrate the two successive lines with the same rhyme, rhythm, length or meter. They are further classified as open as closed couplets. So, it is basically a pair of two lines with the same rhyme scheme. In literature, we have witnessed Shakespeare having an obsession with the use of couplets. For example:
1. "Blessed are you whose worthiness gives scope,
being had, to triumph; being lacked, to scope".(Sonnet 52)
2. "I thank you for this profit and from hence,
I'll love no friend since love breeds such offence".(Othello)
