obliviously

The word "obliviously" has a layered history centered on the concept of forgetting. Its core, the Latin verb oblivisci (to forget), is of uncertain Proto-Indo-European origin but may relate to the idea of smoothing over or wiping away. This root passed into English via the adjective "oblivious," formed by adding the Latin-derived suffix "-ious," meaning "characterized by," to create the sense "characterized by forgetfulness." Finally, the Old English adverbial suffix "-ly" was appended, a common Germanic grammatical tool, to transform the adjective into its current adverbial form. Thus, the literal construction "in a forgetful-characterized manner" evolved to describe the modern abstract meaning of being unaware or unmindful of one's surroundings.
