Origin of oblivion
First recorded in 1350–1400; Middle English, from Middle French, from Latin oblīviōn-, stem of oblīviō “a forgetting,” equivalent to oblīv(īscī) “to forget” + -iō -ion; see ob-
Explanation
Oblivion is the state of being forgotten. Your uncle dreamed of being a rock star, but after recording one hit song, he faded into oblivion. Oblivion can also mean "total forgetfulness" — like what patients with dementia or new parents feel. If you find yourself putting the crackers in the fridge and milk in the cupboards, or forgetting your own phone number, you might be experiencing oblivion. Enjoy it while it lasts.
