A リムリック (limerick) is a humorous five-line poem with a distinct rhythm and rhyme scheme. The typical pattern is AABBA, where the first, second, and fifth lines rhyme with each other, while the third and fourth lines form a shorter couplet. Limericks often feature playful language and whimsical themes, making them popular in children's literature and light verse. The rhythm of a limerick usually follows anapestic meter, which means it has a specific beat that creates a lively flow. Famous examples of limericks can be found in the works of poets like Edward Lear, who is known for his nonsense verse. Limericks are often used in storytelling and entertainment, appealing to both young and adult audiences.
