in prosody, a foot consisting of three long syllables and one short. Of these, grammarians reckon four kinds: the first consisting of an iambus and spondee, as salutantes; the second, of a trocheus and spondee, as concitati; the third, of a spondee and an iambus, as communicans; and the fourth, of a spondee and trocheus, as incantare. See the articles Spondeus, Trocheus, &c.
