Pronunciation

Forms

nuire[1] Old French nuisir beside nuire.[2][3] Anglo-Norman also has noisir and nuser.[4]

Etymology

It is inherited from Old French nuire, inherited from Vulgar Latin *nŏcĕre, an alteration of Latin nocēre (“to harm, do wrong”), differing from the Classical verb in accentuation.[2][5][3][6][7] The Classical form gave Old French nuisir.[2][3][8] Littré explains the pair the same way, deriving Old Occitan nozer from the correct accentuation and Italian nuocere, like the French verb, from the faulty one.[8]

Rey connects the Latin verb with an Indo-European root meaning “to put to death”: the verb first meant “to cause someone's death” before weakening to “to do harm”, while “to kill” was left to necō, the source of noyer1.[3] Cognate with Occitan noire and Catalan noure.[9]

Earliest recorded meaning

The first record is nuisir in Philippe de Thaon's Comput (about 1119), “to do wrong, cause damage”; the form nuire appears in the Eneas about 1160.[2][9]

Semantic evolution

The verb has kept its sense “to harm” throughout, used intransitively with à and also absolutely, “to be harmful” (about 1228); in Old French it could also take a direct object, as in Late Latin.[2][3] Il ne nuira de rien de “it will do no harm to”, that is “it will be useful to”, is dated 1587.[2] The reciprocal se nuire is recorded in 1690 and the reflexive in 1769.[2][3]

The stem gave nuisance (about 1120), and Middle French nuisible (14th century, Oresme) remade Old French nuisable after the Late Latin nocibilis.[3][6]
