obliviate
The origin and history of obliviate.
Etymology
From oblivion + -ate (verb-forming suffix), itself either from Old French oblivion (13th century) or directly from Latin oblīviō, ultimately from oblīvīscor (“to forget”), originally “even out, smooth over, erase”; further perhaps from ob- (“against, towards”) + the root of lēvis (“smooth”) + -scor (“forming inchoative verbs”).
