abominable

From Middle English abhomynable, from Old French abominable, from Late Latin abōminābilis (“deserving abhorrence”), from abōminor (“abhor, deprecate as an ill omen”), from ab (“from, away from”) + ōminor (“forebode, predict, presage”), from ōmen (“sign, token, omen”). Formerly erroneously folk-etymologized as deriving from Latin ab- + homo, literally "away from humankind," and therefore spelled abhominable, abhominal (Hence, Shakespeare puns on this when Hamlet speaks of incompetent actors that "imitate humanity abominably.")
