To reduce to nothing or annihilate completely; to destroy utterly.
From Old French 'anientiser', derived from 'a-' (to) + 'neant' (nothing), ultimately from Latin 'ne' (not) + 'ens' (being). The word literally means 'to make into nothing' and was used in medieval philosophy and theology.
This word reveals how English borrowed extensively from Old French after 1066, but 'anientise' is so rare today that most native speakers have never encountered it—yet it perfectly captures the idea of total obliteration in a single elegant term.
