Etymology

It is borrowed from Late Latin subiūnctīvus (“serving to join”), a grammarians' word of the 4th century.[2][3][1] In Late Latin it described conjunctions that introduce a subordinate clause and vowels that can follow other vowels.[3][4] It was formed on the supine of subiungō (“to yoke, place beneath, subordinate, add”), from sub- (“under”) and iungō (“to join”), the source of French joindre.[2][3] The Latin /un/ became /ɔ̃/, as in the traditional French pronunciation of Latin.[1]

Cognate with Old Occitan subjunctiu, Spanish subjuntivo and Italian soggiuntivo.[5] The mood was called coniūnctīvus in Latin, the source of French conjonctif, used for it from the 15th to the 19th century.[6]

Earliest recorded meaning

It first appears in the 14th century as an adjective meaning “expressing dependence, placed after”, in the phrase ordre subjunctive, in a grammatical text that Thurot cites from a manuscript of 1460.[2] In 1529 Geoffroy Tory wrote of vocales subjonctives, vowels that can follow other vowels.[3][4][7]

Semantic evolution

The adjective was rare after the 16th century.[2] As a noun the word is used by Meigret in 1550 for a verbal mood, and by Aneau in 1551 or 1556 in a sense that is not clear.[2][3][4] From 1660, in Arnauld's grammar of Port-Royal, subjonctif or mode subjonctif is the personal mood of the verb, first seen as the mood of dependence; it took the place of conjonctif and optatif, which the 17th century also used.[2][3][6]

Grammarians now describe it as the mood of will, feeling and subjectivity (doubt, uncertainty) rather than of subordination alone.[3][8] The adjective also qualified what expresses subordination, as in proposition subjonctive (1765), a use now dated.[3][2]
