Anapaest in the context of Long syllable

The foot is the basic repeating rhythmic unit that forms part of a line of verse in most Indo-European traditions of poetry, including English accentual-syllabic verse and the quantitative meter of classical ancient Greek and Latin poetry. The unit is composed of syllables, and is usually two, three, or four syllables in length. The most common feet in English are the iamb, trochee, dactyl, and anapaest. The foot might be compared to a bar, or a beat divided into pulse groups, in musical notation.

A metrical foot is, in classical poetry, a combination of two or more short or long syllables in a specific order; although this "does not provide an entirely reliable standard of measurement" in heavily accented Germanic languages such as English. In these languages it is defined as a combination of one stressed and one or two unstressed syllables in a specific order.

A dactyl (/ˈdæktɪl/; from Greek δάκτυλος 'finger') is a foot in poetic meter. In quantitative verse, often used in Greek or Latin, a dactyl is a long syllable followed by two short syllables, as determined by syllable weight. The best-known use of dactylic verse is in the epics attributed to the Greek poet Homer, the Iliad and the Odyssey. In accentual verse, often used in English, a dactyl is a stressed syllable followed by two unstressed syllables—the opposite is the anapaest (two unstressed followed by a stressed syllable).

An example of dactylic meter is the first line of Henry Wadsworth Longfellow's epic poem Evangeline (1847), which is in dactylic hexameter:

A limerick (/ˈlɪmərɪk/ LIM-ər-ik) is a form of verse that appeared in England in the early years of the 18th century. 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 trimeter with a strict rhyme scheme of ${\displaystyle \mathrm {AABBA} }$, in which the first, second and fifth line rhyme, while the third and fourth lines are shorter and share a different rhyme.

It was popularized by Edward Lear in the 19th century, 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 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.
