An Etymological Dictionary of the German Language/trinken
trinken, vb., ‘to drink,’ from the equiv. MidHG. trinken, OHG. trinchan; a common Teut. str. vb.; comp. Goth. drigkan, AS. drincan, E. to drink, Du. drinken, OSax. drinkan. From OTeut. are derived the Romance cognates, Ital. trincare, Fr. trinquer, ‘to touch glasses.’ The str. verbal root drink (Aryan dhreng) is not found in non-Teut.; on the other hand, the Aryan root pô, ‘to drink’ (comp. Sans. pâ, Gr. πω-, Lat. pô-tus, &c.), is wanting in Teut. — Comp. Trank, Trunk.
