Anapaest
（重定向自Anapestic）
An anapaest (also spelled anapæst or anapest, also called antidactylus) is a metrical foot used in formal poetry. In classical quantitative meters it consists of two short syllables followed by a long one; in accentual stress meters it consists of two unstressed syllables followed by one stressed syllable. It may be seen as a reversed dactyl. This word comes from the Greek ανάπαιστος, anápaistos, literally "struck back" (a dactyl reversed), from ana and -paistos, verbal of παίειν, paíein "to strike."
