A limerick (/ˈlɪmərɪk/ LIM-ər-ik)[1] is a form of verse that appeared in Limerick, County Limerick, Ireland in the early years of the 18th century.[2] In combination with a refrain, it forms a limerick song, a traditional humorous drinking song often with obscene verses. It is written in five-line, predominantly anapestic and amphibrach[3] trimeter with a strict rhyme scheme of AABBA, in which the first, second and fifth line rhyme, while the third and fourth lines are shorter and share a different rhyme.[4]
It was popularized by Edward Lear in the 19th century,[5] although he did not use the term. From a folkloric point of view, the form is essentially transgressive; violation of taboo is part of its function. According to Gershon Legman, who compiled the largest and most scholarly anthology, this folk form is always obscene[6] and the exchange of limericks is almost exclusive to comparatively well-educated men. Women are figuring in limericks almost exclusively as "villains or victims". Legman dismissed the "clean" limerick as a "periodic fad and object of magazine contests, rarely rising above mediocrity". Its humour is not in the "punch line" ending but rather in the tension between meaning and its lack.[7]
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.[8]
