also anapaest, "two short syllables followed by a long one," 1670s, from Latin anapestus, from Greek anapaistos "struck back, rebounding," verbal adjective from anapaiein "to strike back," from ana- "back" (see ana-) + paiein "to strike," from PIE *pau- "to cut, strike, stamp" (see pave). So called because it reverses the dactyl.
