the.com/avenger

means Someone who inflicts punishment or harm on behalf of a wrong done to themselves or another.

from From Old French 'avengier,' built on Latin 'vindicare' — to claim, vindicate, or avenge — the same root that gives us 'vindictive' and 'vindicate.' The 'a-' prefix is an intensifier, so the word literally pushes 'vindicate' toward action: not just proving the wrong, but settling it.
