Here's a breakdown of its evolution:
* Latin "renegare": This verb means "to deny, to renounce, to abjure".
* Latin "renegatus": This is the past participle of "renegare", meaning "denied", "repudiated", or "forsaken".
* Old French "renegat": This word took on the meaning of "apostate", "renegade", or "traitor".
* Middle English "renegate": This word entered English with the same meaning as the Old French term.
* Modern English "renege": This form of the word shifted from a noun to a verb, signifying "to break a promise or agreement", "to go back on one's word", or "to repudiate an obligation".
So, while "renege" might sound like a modern word, it actually has roots in ancient Latin and has undergone several transformations throughout its linguistic journey.
