Origin: 1685–95; < Latin verminātus, past participle of vermināre to be infested with maggots, to have racking pains, equivalent to vermin(a) racking pain + -ātus-ate1; dual sense of vermināre by association with vermis worm, maggot, vermin- being taken, perhaps erroneously, as an extended stem of this word
