How is a limerick typically structured?

A limerick is a specific form of poetry that is characterized by its structure and rhyme scheme. The correct answer highlights that a limerick typically consists of five lines, where the first, second, and fifth lines are longer and share an alternating rhyme, while lines three and four are shorter.

To clarify, the first, second, and fifth lines of a limerick usually contain three metrical feet, often iambic trimeter, while the third and fourth lines typically have two metrical feet, iambic dimeter. This creates a distinctive rhythm and a playful tone, which is the hallmark of limericks. Additionally, the rhyme scheme follows an AABBA pattern, wherein the longer lines rhyme with each other and the shorter lines also rhyme, enhancing the lyrical quality of the poem.

This particular structure and rhyme scheme is what sets limericks apart and contributes to their humor and lightheartedness, making them a popular choice for whimsical poetry.
