Definition
Irredeemable means something that cannot be saved, corrected, or improved. Think of a character in a movie who is so evil that there's no chance of redemption; they're irredeemable. It implies a situation beyond repair or a person beyond help. Unlike something that can be salvaged, irredeemable things are considered lost forever. For example, an irredeemable debt is one that can never be repaid. It suggests something beyond any reasonable solution.
