dactyl

A dactyl is like a finger, having one long part followed by two short stretches.

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).
