I am trying to rationalize the language of risk and am stuck on antonyms of hazard and threat (both as nouns), where hazard is something in a harmless state, threat is in a harmful state. The antonym of hazard would need to mean something in a not-helping-but-could-change-to-helping state, the antonym of threat would need to mean something in a helping state. Any ideas? Some potential antonyms (such as ally for threat) surely count as antonyms but do not seem generalizable enough conceptually to include other antonyms (such as contributor)..
