A limerick is a type of closed-form poetry that often has a light, humorous subject matter. It is a form of verse that appeared in England in the early years of the 18th century). The standard form of a limerick is a stanza of five lines, with the first, second, and fifth lines rhyming with each other and having three feet of three syllables each, while the shorter third and fourth lines also rhyme with each other but have only two feet of three syllables). The third and fourth lines are usually anapaestic, or one iamb followed by one anapaest, while the first, second, and fifth lines are usually either anapaests or amphibrachs).
Limericks are often humorous or obscene in nature and follow a five-line AABBA rhyme scheme. They are intended to entertain the audience. Some limericks contain details that are not printable.
