What is the primary characteristic of a limerick?

The primary characteristic of a limerick is its specific rhyme scheme and rhythm. Limericks are a form of humorous poetry consisting of five lines with a distinct pattern. The rhyme scheme typically follows an AABBA format, where the first, second, and fifth lines rhyme with one another, while the third and fourth lines form a separate rhyming pair. Additionally, these lines generally incorporate a specific meter, often featuring a rhythm of anapestic or amphibrachic feet.

This structured format contributes to the playful and often whimsical nature of limericks, making them enjoyable and memorable. The consistent rhyme and rhythm set limericks apart from other types of poetry, emphasizing their character as light-hearted and often humorous expressions.
