What does Purgatory Mean?

In Catholicism, purgatory is a place of purification through suffering after death. It comes from the Latin word ‘purgare’ which means ‘to purify’. Catholics believe in the necessity of reparation for sins, even after forgiveness (much in the same way that a criminal may still receive a prison sentence, even if he’s sorry for what he’s done). This is seen as justice for having offended God.
