Word History

Etymology

Latin obnoxius "under obligation, subservient, liable, exposed to, vulnerable" (of uncertain origin) + -ous

Note: Latin obnoxius has traditionally been taken to be a parasynthetic derivative from the phrase ob noxiam "due to wrongdoing, on account of bad behavior" (see noxious), but this explanation does not account for the primary senses of the word. Ernout and Meillet (Dictionnaire étymologique de la langue latine) take -noxius as a desiderative derivative from the base of nancīscī "to acquire" (see enough entry 1), parallel to anxius "worried"/angere "to strangle, distress" (see anxious), alsius "liable to injury from cold"/algēre "to be cold." The English sense "objectionable" is probably due to influence of noxious and its etymon, Latin noxius.
