Indignant → It is formed from "in-" (meaning not) and "dignus" (meaning worthy). The word "indignant" describes a feeling of anger or annoyance at what is perceived as unfair treatment, thus meaning not feeling worthy or deserving of the situation.
Think of feeling 'not worthy' ('in-') of something unfair ('dignus') — that's why indignant means feeling angry about unfair treatment.
