Redemption is the buying back of something. You might try for redemption by attempting to buy back a bike you sold, or you might attempt to buy back your soul after you steal someone else’s bike.
Redemption comes from the Latin word redimere, a combination of re(d)-, meaning “back,” and emere, meaning “buy.” Redemption is what some people claim happens to your soul when you're saved from evil forces. You might pray for redemption — to the tooth fairy, to Zeus, or to some other kind of invisible being — in the hopes that an all-powerful being can save your soul. Redemption can also refer to the repayment of a debt.
