Forms
subiūnctīvus (feminine subiūnctīva, neuter subiūnctīvum); first/second-declension adjective[1] It is also spelled subjūnctīvus.[1][2]
Etymology
It is formed from Latin subiungō (“to subjoin, subordinate”) + -īvus,[1][3] a calque from Ancient Greek ὑποτακτικός (hupotaktikós).[1] Etymonline also takes the Latin name of the mood to be probably a loan translation of the Greek grammatical term by Roman grammarians.[4]
Earliest recorded meaning
Köbler's first record is the grammarian Charisius (about 362 AD),[5] who calls conjunctions such as si and cum subiunctivae, “subjoining”, because they introduce a dependent clause.[2][6]
Semantic evolution
It is a term of the late grammarians: Diomedes and Priscian name the subjunctive mood modus subiunctivus,[3][2] and Priscian also calls subiunctivae the vowels that can follow other vowels.[6][2] Its general sense is “serving to join, connecting”.[2][3] In British Medieval Latin it meant “subjoined, dependent”, and as a noun, or with articulus, the relative pronoun.[7] English subjunctive (adjective 1520s, noun 1620s) comes from it.[4]
