trochee n.

metrical foot consisting of a long followed by a short syllable, or an accented followed by an unaccented one, 1580s, from French trochée, from Latin trochaeus "a trochee," from Greek trokhaios (pous), literally "a running (foot)," from trekhein "to run" (see truckle (n.)). Its rapid movement rendered it a fit accompaniment to dances.

The English trochee is, in fact, rather an uncanny foot .... It is (let us remember our Anglo Saxon) Lilith—older than Eve, in a manner—dethroned by her, but never quite forsaken ; "kittle" to deal with, but of magical and witching attractions when taken in a kind and coming mood. [George Saintsbury, viewing it with the iamb, in "History of English Prosody," 1908]
