Pronunciation

  • /kəˈlæb.ə.ɹeɪt/, /kəˈlæb.ɹeɪt/[1]

Etymology

It is borrowed from Late Latin collabōrō (“to work together”), from its past participle collabōrātus,[2][3][4][5][6][7] or perhaps from French collaborer, itself from the Latin verb.[8][9] The Latin verb is formed from com- (“together”) and labōrō (“to work”),[3][8][6][4] a verb from the Latin noun for toil or work, the source of labor.[3][6] Etymonline also allows that it may be a back-formation from collaborator, recorded from 1802 and itself from French collaborateur.[9][6][8]

Earliest recorded meaning

To work together with another or others, especially on a literary or artistic work: 1871, in a letter printed in J. H. Appleton's Life and Literary Relics.[8][6][2] Etymonline finds the verb implied in “collaborating” in 1845.[9]

Semantic evolution

The agent noun came first: collaborator is recorded from 1802, in a letter of Jeremy Bentham, after French collaborateur, which was itself sometimes used in English.[8][6][9] The noun collaboration followed in 1860, in the writings of Charles Reade, borrowed from French.[6] During the Second World War the verb took on a bad sense, to cooperate treacherously with the enemy, especially with an occupying power; the OED records it from 1941,[8][6][9] and Barnhart thinks it probably a translation of French collaborer as used in 1940.[6] Collaborator gained the matching sense in 1943.[8]
