verb/nɛ.twa.je/
to clean; to wipe clean
“Nettoyer les fesses du bébé.” — Clean the baby's bottom
Inherited from Middle French nettoyer, from Old French netoiier, a restructuring (based on net (“clean (adj.)”)) of Old French noiier (“to clean”), from Vulgar Latin *nitidiāre, a verb based on Latin nitidus (“shining, polished”), which took on the meaning of 'clean'. By surface analysis, net + -oyer.
