Feel resentment, take offense, as in Aunt Agatha is quick to take umbrage at any suggestion to do things differently. This expression features one of the rare surviving uses of umbrage, which now means "resentment" but comes from the Latin umbra, for "shade," and presumably alludes to the "shadow" of displeasure. [Late 1600s]
