1. Ashamed, humiliated, mortified refer to a condition or feeling of discomfort or embarrassment. Ashamed focuses on the sense of one's own responsibility for an act, whether it is foolish, improper, or immoral: He was ashamed of his dishonesty. She was ashamed of her mistake. Humiliated stresses a feeling of being humbled or disgraced, without any necessary implication of guilt: He was humiliated by the king. Both words are used equally in situations in which one is felt to be responsible for the actions of another: Robert felt humiliated by his daughter's behavior. Mom was ashamed of the way I looked. Mortified represents an intensification of the feelings implied by the other two words: She was mortified by her clumsiness.
