[Fr. joindre; It. giugnere; from L. jungo, jungere; jungo for jugo; Sp. and Port. juntar, to join; L. jugum; Eng. yoke; Gr. {foreign} and {foreign}, a yoke, and a pair; {foreign} to yoke; {foreign} to join; Ch. {foreign}; Syr. {foreign} zug; Ar. {foreign} zauga, to join, to couple, to marry, to pair; Eth. {foreign} zog, a pair, as in Arabic. It signifies also in Syriac, to rage, to cry out; showing that the primary sense is to strain, to stretch, to extend, precisely as in span.]

1. To set or bring one thing in contiguity with another. Woe to them that join house to house, that lay field to field. Is. v.
2. To couple; to connect; to combine; as, to join ideas. Locke.
3. To unite in league or marriage. Now Jehoshaphat had riches and honor in abundance, and joined affinity with Ahab. 2 Ch. xviii. What God hath joined together, let not man put asunder. Matth. xix.

6. To unite in concord. But that ye be perfectly joined together in the same mind, and in the same judgment. 1 Cor. i. The phrase, to join battle, is probably elliptical, for join in battle or it is borrowed from the Latin, committere praelium, to send together the battle. In general, join signifies to unite two entire things without a breach or intermixture, by contact or contiguity, either temporary or permanent. It differs from connect, which signifies properly, to unite by an intermediate substance. But join, untie, and connect are often used synonymously.
