indignation

The word indignation originates from the Latin indignatio, which itself is derived from indignari, meaning "to deem unworthy" or "to be displeased at". This Latin verb is a compound of the negative prefix in- ("not") and the root dignus ("worthy, proper"). Thus, the core logic is a feeling triggered by an event or action judged as "not worthy"—that is, beneath proper standards of conduct or fairness. Over time, this sense of judging something as unworthy evolved specifically into the strong, morally charged anger we associate with the modern term, capturing the reaction to perceived injustice or insult.

Structure: in (not) + dign (worthy) + ation (noun suffix) - in: Latin prefix meaning "not". - dign: From Latin root dignus, meaning "worthy". - ation: Latin-derived noun-forming suffix indicating an action, process, or state.
