Origin & History of “join”

Join goes back ultimately to a prehistoric Indo-European *jug- (which also produced English adjust, conjugal, jostle, joust, jugular, juxtapose, subjugate, yoga, and yoke). Its Latin descendant was jungere ‘join’, which passed into English via joign-, the present stem of Old French joindre. The Latin past participial stem junct- gave English junction (18th c.) and juncture (14th c.), and also, via Spanish, junta (17th c.) (etymologically a body of people ‘joined’ together for a particular purpose, hence a ‘governing committee’).
