(Latin: atterere, to rub)

Contrition for sin without perfect motive; a sorrow of soul and a hatred of sin committed, with a firm purpose of never sinning again, the sorrow being based not on the pure love of God, whom sin has grievously offended, which would be perfect contrition, but on some inferior though supernatural motive such as the loss of heaven, or the punishment of hell, or the heinousness of sin itself.
