IPA: /fɔːrˈseɪkər/
KK: /fɔrˈseɪkər/
A person who abandons or gives up something, often in a way that is considered disloyal or unfaithful.
He was seen as a forsaker of his principles when he changed his beliefs for personal gain.
Forsaker → It is formed from "for-" (meaning away or off) and "sacrare" (from Latin, meaning to make sacred or to consecrate). The word refers to someone who turns away from or renounces something sacred or valued.
Think of someone who turns 'away' ('for-') from something they once held 'sacred' ('sacrare') — that's why a forsaker is someone who renounces or abandons something important.
