Unprofessed → It is formed from "un-" (meaning not) and "profess" (from Latin "profiteri", meaning to declare openly). The word "unprofessed" means not declared or not openly acknowledged.
Think of 'not' ('un-') declaring something openly ('profess') — that's why unprofessed means something that is not openly acknowledged.
