Pronunciation

  • Ecclesiastical: [konˈjuŋk.t͡si.o][1]

Forms

coniūnctiō f (genitive coniūnctiōnis); third declension[1]

Etymology

It is from Latin coniungō (“to join together”) + -tiō.[2][3] De Vaan lists it under iungō (“to join, yoke”), from the nasal present Proto-Indo-European *(H)iu-n-g- (“to yoke”), cognate with Sanskrit युनज्मि (yunájmi, “I yoke”), Ancient Greek ζεύγνυμι (zeúgnumi, “to yoke”) and Lithuanian jùngti (“to join, yoke”).[4]

Earliest recorded meaning

De Vaan dates it from Varro,[4] who speaks of the union of fire and water.[2] Köbler dates it from Cicero.[5]

Semantic evolution

Poets avoid it and the older writers rarely use it; it is frequent in Cicero and Vitruvius.[3] It is the joining of things and the point where they meet: Cicero describes part of a town, cut off by a narrow strait, joined again by a bridge where two harbours meet.[2] Vitruvius uses it of a conjunction of heavenly bodies.[2] In rhetoric and grammar it is the arrangement of words, the forming of a word from parts, and, in Cicero, a connecting particle, a conjunction.[2] Between people it is a bond of friendship or alliance, as Cicero's union with Caesar, and a connection by marriage.[2] In logic it is a compound proposition.[2]

Church Latin has it for union, joining together.[6] Medieval Latin used it for marriage, a bestowal, vassalage and an astronomical conjunction.[7] English conjunction (late 14th century), first of planets meeting in the sky, came through Old French conjonction.[8]
