Etymology Origin:
The word "oblivious" traces back to Latin oblivisci, meaning "to forget." The root obliv evolved into Old French oblier (to forget) before entering Middle English as oblivious. The suffix -ious was added to form an adjective, originally implying "forgetful" but later shifting to mean "unaware" in modern usage. The transition reflects how forgetting leads to a state of unconsciousness or lack of awareness.
