It will be noted that the dactyl is very closely related in expression to the trochee, and the anapest to the iambic.
This foot, which is the opposite of the dactyl, is known as the anapest.
An anapest is a three-syllable foot accented on the last syllable.
Where arm in arm two dancers are entwined,And whirl themselves with strict embracements bound,their feet an anapest do sound.
This may occur when the accent is upon the last syllable of the foot; that is, when the foot is an iambus or an anapest.
It is hovering between the form of the first two feet and the anapest of the last foot.
“anapest” comes from a Greek verb which means “strike back”; an anapest is a reversed dactyl.
But Voltaire now quit the anapest and dactyl and devoted his best hours to taking fencing lessons.
The trochee and the dactyl are interchangeable; and the iambus and the anapest are interchangeable.
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.
