n. - A state or place of purification after death; according to the Roman Catholic creed, a place, or a state believed to exist after death, in which the souls of persons are purified by expiating such offenses committed in this life as do not merit eternal damnation, or in which they fully satisfy the justice of God for sins that have been forgiven. After this purgation from the impurities of sin, the souls are believed to be received into heaven.
