Forms

ineffectif (feminine ineffective)[1][2]

Etymology

It is formed from French in- + effectif, with the negative prefix.[3][1][4][2]

Earliest recorded meaning

The first record is from Armand-Jean Le Bouthillier de Rancé at the end of the 17th century, quoted by the Trévoux dictionary in 1721;[3] the GLLF dates Rancé's use to 1697 and gives the Encyclopédie (1765) as the next record.[4] It already meant “not followed by any effect”.[3][4]

Semantic evolution

The word has kept the single sense it was formed with: something that produces no effect or is never carried into action, the opposite of effectif.[3][2] The TLFi labels it rare; its 19th- and 20th-century examples come from Gobineau, Valéry and a translation of Freud.[3]
