Would that our sins had built-in qualities of oblivescence such as our dreams have.
Oblivescence dates from the late 19th century and is a later spelling of obliviscence, whichdates from the late 18th century. The spelling oblivescence arose by influence of the far more common suffix escence. The English noun is a derivative of the Latin verb oblīviscī “to forget,” literally “towipe away, smooth over.” The Latin verb is composed of the prefix ob- “away,against” and the same root as the adjective lēvis “smooth.”
