animadversion

Animadversion comes ultimately from the Latin phrase animum advertere, meaning "to turn the mind to." It is easy to see how we also get "adverse" and "adversary" from "advertere," especially when we remember that "to turn to" easily becomes "to turn against." Other English words descended from "advertere" include advert, meaning "to turn the attention (to) or "to make reference (to)," and "advertise."
