Yuñjati [Vedic yunakti, yuñjati & yuñkte, yuj; cp. Gr. zeu/gnumi, Lat, jungo to unite, put together (pp. junctus=Sk. yukta, cp. E. junct -- ion); Lith. jùngin. The Idg. root *i̯eug is an enlarged form of *i̯eṷe "to unite," as in Sk. yanti, yuvati, pp. yuta; f. yuti, to which also Lat. jūs=P. yūsa. The Dhtp gives several (lit. & fig.) meanings of yuj, viz.
