Indignation is an emotion, and is considered to be a type of anger. Indignation is often composed of anger, disgust, contempt, and resentment. Simply, indignation can be defined as anger that is caused by something that is unfair or wrong. In more detail, indignation is defined as, "a discrete social emotion specifying disapproval of a blameworthy action explicitly perceived as violating the objective order, and, implicitly perceived as injurious to the self-concept". Indignation is an attribution-related emotion causing this emotion to be very personal to those experiencing it. Indignation has been described as the opposite emotion to respect even though it has become synonymous with anger, whose opposite is gratitude, in the modern English usage.
