avenger

The word 'avenger' is built upon the verb 'avenge', which entered English from Old French avengier. This French term originated from the Latin ad- (meaning 'to') combined with vindicare (meaning 'to lay claim to, to avenge, to punish'). The Latin vindicare itself is related to vindex (a claimant, defender, avenger), a word of uncertain but possibly Italic origin. The suffix '-er' is a native English agent-forming suffix, used to denote one who performs an action. Thus, an 'avenger' is, literally, "one who carries out vengeance," a concept that has evolved from the ancient legal and personal notion of claiming justice or inflicting punishment for a wrong, now often carrying connotations of personal or moral retribution.

Structure: avenge + er - avenge: From Old French avengier, from Latin ad- (to) + vindicare (to claim, avenge, punish). The core sense is "to inflict retribution." - er: A Germanic agent noun suffix (from Old English -ere), indicating "a person or thing that performs the action of the verb."
