IPA: /ɪnˈdɪɡnəntli/
KK: /ɪnˈdɪɡnəntli/
In a way that shows anger or annoyance at something perceived as unfair or wrong.
She responded indignantly when she heard the unfair accusation.
Indignantly → It is formed from "indignus" (meaning unworthy or not deserving) and the suffix "-ly" (meaning in a manner). The word "indignantly" describes the manner of feeling unworthy or offended, often in response to perceived injustice.
Think of feeling 'unworthy' ('indignus') and expressing that feeling 'in a manner' ('-ly') — that's why indignantly means responding with offense or anger.
