Forms

énerver[1] Old French esnerver (pronominal soi esnerver).[2][3]

Etymology

It is borrowed from Latin ēnervō (“to remove the sinews; to weaken, exhaust”),[2][4][5] from ex- in a privative sense and nervus (“sinew, tendon”), the source of nerf.[4][6]

Earliest recorded meaning

It first appears in the first quarter of the 13th century, in the pronominal soi esnerver in the Renclus de Molliens, in the figurative sense taken from Latin, “to lose one's strength”.[2][4]

Semantic evolution

For centuries the verb meant “to deprive of strength or energy”, of the body, the mind or a thing: Jean de Meun uses it about 1265 for weakening a power.[6][7] The literal sense “to cut the tendons” is recorded in 1594, and in the 17th century it named the torture of cutting a person's tendons (1694).[4][2]

The old meaning still lived in the 19th century, especially in the past participle énervé “listless, without vigour”, but it was driven out by a new and nearly opposite one, “to irritate, make nervous”.[4] The present participle énervant has it in 1867 and the verb in 1882, after énervement; the TLFi dates the sense of exciting the nerves to Barbey d'Aurevilly in 1836.[4][2] Bloch and Wartburg place this now dominant sense in the 19th century.[5]
