Forms

ignorer[1]

Etymology

It is borrowed from Latin īgnōrō (“not to know”),[2][3][4][5] from īgnārus (“not knowing”), formed from in- and gnārus (“knowing”),[3][6] the source of ignare.[3]

Cognate with Old Occitan ignorar, Spanish ignorar and Italian ignorare.[7]

Earliest recorded meaning

The 14th-century Girart de Roussillon (about 1330) has tout senz rien ignorer “all, without missing anything”, in the Latin sense “not to know”.[2][7]

Semantic evolution

At the end of the 14th century it also meant “to be negligent” (Froissart).[3][7] In 1564 it was used for not knowing someone's existence or worth, and the critics ignorèrent an artist whose work they did not know (Piron).[8][3] Fénelon (1714) has it for “to pretend not to know (someone)”, and Furetière (1690) for “not to take into account”;[8][3] the modern il m'ignore “he cuts me dead” belongs here.[9]

S'ignorer “not to know oneself” is in Pascal, and un artiste qui s'ignore is one unaware of his own nature.[3][9] The old construction en ignorer (1579) survives in the legal formula pour que nul n'en ignore.[2][3] Nul n'est censé ignorer la loi “ignorance of the law is no excuse” is a common maxim.[9][1]
