The following is a list of auto-antonyms, words which have two or more definitions where each is the opposite of the other, yet thanks to the beauty of language these words are rarely confusing to most of us:

“Appropriate” can mean “to give (money or assets) to” or “to delegate to,” as well as “to take something (for one’s own use).”

"Bound" can mean "tied into immobility" or "leaping, jumping.”
