Forms

conjuguer[1] First written conjuger;[2] conjuger and conjuguer are both found in 1596.[2]

Etymology

It is borrowed from Latin coniugō (“to join together, to marry”),[3][4][1] formed from com- (“with”) and iugō (“to join, to tie (vines)”),[4][5] from iugum (“yoke”), the source of joug.[5][6][7] In late grammatical Latin it already meant “to conjugate a verb”;[2] in French the grammatical sense was taken up after conjugaison.[3][4]

Rey notes that the Latin simple verb is a durative beside iungō (“to join”), so that the compound, “to unite, to marry”, was a doublet of coniungō, the source of conjoindre, and the two French verbs share some uses.[4]

Earliest recorded meaning

It is first found in 1572 in Ramus's Grammaire française, in the grammatical sense.[3][2]

Semantic evolution

The grammatical sense, “to set out all the forms of a verb”, came first;[3][4] the general sense “to join, associate, bring together” followed in 1596 and lives on in the written language, as in conjuguer ses efforts.[3][4] Littré in 1873 still called the sense “to unite” little used.[6]

The Latin idea of marriage survived jokingly in se conjuguer, after Latin conjungo “I join”, from the wedding formula, used as a noun for “marriage” from 1694.[4] The past participle conjugué became an adjective, first meaning “married”, then with technical uses: anatomy (nerfs conjugués, 1690) and botany (feuilles conjuguées, 1753, and in 1803 the noun conjuguées for a group of algae).[3][4]
