means A mythical creature with the upper body of a human and the lower body of a donkey, a lesser-known cousin of the horse-bodied centaur.

from From Greek "onos" (donkey) plus "kentauros" (centaur), literally a "donkey-centaur." The beast wandered out of ancient Greek and Roman natural-history lore into the medieval bestiary, where it was often given a moralizing spin — a symbol of duplicity or of a divided, beastly nature. The donkey half is the key: "onos" is the same root behind "onager" (the wild ass) and even "onomatopoeia" shares the unrelated "onoma" (name), so don't be fooled by the resemblance — only the donkey is real here.
