Forms
adjoindre[1] Old French ajoindre, still current in the 16th century; the spelling with ⟨d⟩ dates from the 14th century.[2][3][4]
Etymology
It is inherited from Old French ajoindre, inherited from Latin adiungō (“to join to, add”), respelled with ⟨d⟩ after the written Latin form from the 14th century.[2][3][4][1] The Latin verb is formed from ad- (“to”) and iungō (“to join”), the source of joindre.[3][5]
Cognate with Italian aggiungere; in the Gallo-Romance dialects the verb often means “to reach”, like Romanian ajunge.[4]
Earliest recorded meaning
The first record, in the Old French Dialogues of Gregory (second half of the 12th century), has ajoindre meaning “to add”; at the end of the century it meant “to unite”, and about 1200 the reflexive s'ajoindre “to join oneself (to something)”.[2]
Semantic evolution
In Old and Middle French ajoindre meant “to add” and “to unite”, and was used intransitively for “to be next to” (about 1300).[3] Until the 17th century its sense differed little from that of joindre.[4] The relatinised form came to be used for putting people together with others, whence s'adjoindre à quelqu'un (1538); Oresme used it for joining one thing to another.[3]
The past participle adjoint was used as a noun for an ally or associate (1337) and later took specialised senses in law (1549), local administration (the deputy mayor, 1795) and the army (1825).[3][2] In modern French the verb mainly means to assign someone as a helper, and in the 19th century it took up again the old sense of adding one thing to another.[6]
