oblivious of, oblivious to
Oblivious means “unaware,” “unmindful” or “forgetful” (in the sense of being distracted rather than unable to remember clearly). It can be followed by the preposition of or to.
- The professor was oblivious of day-to-day routines and often forgot to eat.
- Stephen continued working, oblivious to the workers setting up new office cubicles next to his.
Sometimes no preposition is used after this adjective.
- The tractor leaked dirty oil onto the driveway, but the driver was oblivious.
