Etymology

It is inherited from Proto-Italic *jung-e/o-, inherited from Proto-Indo-European *(H)iu-n-g- (“to yoke”), a nasal present of the root *yewg- (“to yoke, join”), made thematic in Latin.[2][1] From the same root come iugum “yoke”, coniunx “spouse” and iūgerum, the land a team of oxen could plough in a day.[2][3]

Cognate with Sanskrit युनक्ति (yunákti, “yokes”), Ancient Greek ζεύγνυμι (zeúgnumi, “to yoke”), Lithuanian jùngti (“to yoke, join”) and Hittite iūk- (“yoke”).[2][4][3]

Earliest recorded meaning

It is found from Plautus onwards,[2] whose madman cries “you order me to take horses that are yoked yet unbroken”.[4]

Semantic evolution

It meant to yoke or harness animals, as Pacuvius' winged snakes yoked to a chariot, and to join things together, as Caesar's boats joined into a bridge.[4] It meant to clasp hands, as in Virgil, to bring things side by side, and to make something by combining parts.[4]

It meant to unite troops or people, as friends or allies, as in Terence, and to form a friendship or marriage.[4] It also meant to share an activity, to follow one thing directly on another, to combine qualities, as Cicero's “charm joined with seriousness”, and to connect in thought.[4] In grammar the passive meant to govern a case.[1] It survives as Italian giungere, French joindre and Portuguese jungir.[1] English join and joint came through Old French about 1300.[5]
