If you redeem yourself or your reputation, you do something that makes people have a good opinion of you again after you have behaved or performed badly.

When something redeems an unpleasant thing or situation, it prevents it from being completely bad.

If you redeem a debt or money that you have promised to someone, you pay money that you owe or that you promised to pay.

If you redeem an object that belongs to you, you get it back from someone by repaying them money that you borrowed from them, after using the object as a guarantee.

In religions such as Christianity, to redeem someone means to save them by freeing them from sin and evil.
