renegade

the word 'renegade' entered english in the late 16th century from spanish 'renegado', which itself came from medieval latin renegatus, the past participle of renegare meaning 'to deny'. this latin verb is a compound of the intensive prefix 're-' and 'negare' (to deny). originally, it was a term for a christian who converted to islam, essentially one who 'denied again' their faith. the core semantic logic moves from the literal act of denial and turning back on one's previous allegiance to the modern abstract sense of a traitor or deserter from any cause or group.

Structure: re (again, back) + neg (deny) + ade (noun suffix) re- (latin prefix, meaning "again" or "back"); neg- (from latin negare, meaning "to deny"); -ade (a noun-forming suffix of latin origin via french and italian, often indicating an action or a person involved in an action).
