Limerick (poetry)

A limerick is a form of poetry in five-line, predominantly anapesticmeter with a strict rhyme scheme (AABBA), which is sometimes obscene with humorous intent. The third and fourth lines are usually shorter than the other three. The following example is a limerick of unknown origin:

The limerick packs laughs anatomical
Into space that is quite economical.
But the good ones I've seen
So seldom are clean
And the clean ones so seldom are comical.

The form appeared in England in the early years of the 18th century. It was popularized by Edward Lear in the 19th century, although he did not use the term. Gershon Legman, who compiled the largest and most scholarly anthology, held that the true limerick as a folk form is always obscene, and cites similar opinions by Arnold Bennett and George Bernard Shaw, describing the clean limerick as a "periodic fad and object of magazine contests, rarely rising above mediocrity". From a folkloric point of view, the form is essentially transgressive; violation of taboo is part of its function. Lear is unusual in his creative use of the form, satirising without overt violation.

The standard form of a limerick is a stanza of five lines, with the first, second and fifth rhyming with one another and having three feet of three syllables each; and the shorter third and fourth lines also rhyming with each other, but having only two feet of three syllables. The defining "foot" of a limerick's meter is usually the anapaest, (ta-ta-TUM), but catalexis (missing a weak syllable at the beginning of a line) and extra-syllable rhyme (which adds an extra unstressed syllable) can make limericks appear amphibrachic (ta-TUM-ta).

The first line traditionally introduces a person and a place, with the place appearing at the end of the first line and establishing the rhyme scheme for the second and fifth lines. In early limericks, the last line was often essentially a repeat of the first line, although this is no longer customary.
