Pronunciation

  • Classical: [kɔnˈjʊŋ.ɡoː][1]
  • Ecclesiastical: [konˈjuŋ.ɡo][1]

Forms

coniungō (present infinitive coniungere, perfect active coniūnxī, supine coniūnctum); third conjugation[1] It is also written conjungō; an inscription from Pompeii has coiunxit.[1][2]

Etymology

It is formed from Latin con- (“with, together”) + iungō (“to join, yoke”).[2][1][3] De Vaan traces iungō to Proto-Italic *jung-e/o-, from the nasal present Proto-Indo-European *(H)iu-n-g- (“to yoke”), cognate with Sanskrit युनक्ति (yunákti, “yokes”), Ancient Greek ζεύγνυμι (zeúgnumi, “to yoke”) and Lithuanian jungti (“to yoke”).[4]

Earliest recorded meaning

De Vaan dates it from Plautus.[4] Varro speaks of body and soul quae fuerint coniūncta in homine, “which were joined in a man”.[2]

Semantic evolution

Coniungere is “to join together, connect, yoke”, also sexually and of words linked by conjunctions (Gellius: atque joins words).[2][5][1] It is to place side by side, to build into one structure, of armies “to unite forces”, to compose by joining, to link two places, and to join in time.[2] With people it is “to unite” in friendship or alliance, “to join in marriage” (Livy), and to form a friendship or relationship.[2][1]

Church Latin glosses it “to join, bind together, unite”.[6] English conjoin comes from it through Old French in the late 14th century.[7]
