Etymology

The word "ignore" originates from Latin ignorare ("not to know, disregard"), combining the negative prefix in- (here assimilated as ig-) and gnarus ("knowing"). The term entered Middle French as ignorer before being adopted into English in the 16th century. Initially meaning "to be unaware of," it evolved to imply intentional disregard by the 17th century. The morpheme nore preserves the Latin root gnarus, though its standalone form is obsolete in modern English.
