Final answer:
A humorous verse with a rhyme scheme of AABBA, where lines three and four have two feet and lines one, two, and five have three feet is known as a limerick.
Step-by-step explanation:
The verse form defined as a humorous verse with the rhyme scheme AABBA, where lines three and four have two feet and lines one, two, and five have three feet is a limerick. Unlike iambic pentameter, which is a style of poetic meter where each line contains five sets of iambs or ten syllables, a limerick has a specific structure that is both shorter and rhythmically distinct for its comedic effect.
A classic example of a limerick could start with 'There once was a man from Nantucket,' which clearly illustrates the distinctive rhythm and rhyme pattern that defines this poetic form.
