Couplet:
A couplet is a pair of successive lines of verse having the same meter and often forming a
complete thought. Couplet generally appears in
poetry. A couplet generally consists of two lines of verse which rhyme
together & are of the same length. “The Night
Before Christmas,” “The Canterbury Tales” are
written entirely in couplets. Shakespeare and Alexander Pope
were both well known for their writing in heroic couplets.
Example of couplet:
"A little learning is a dangerous thing;
Drink deep, or taste not the Pierian spring."
Here the last word of the first line and second line has the
similar sounds ‘ing’.
