An Etymological Dictionary of the German Language/Annotated/gießen
gießen, verb, from the equivalent Middle High German gieȥen, Old High German gioȥan, ‘to pour, cast metal, form, pour out, spill, stream’; corresponding to Gothic giutan, ‘to pour’ (Old Icelandic gjóta, ‘to throw young, blink with the eyes’), Anglo-Saxon geótan, Dutch gieten; a strong verbal root common to Teutonic, from pre-Teutonic ghud, whence also the Latin root fud in fundo, ‘I pour.’ This root is probably connected with the equivalent root ghu (Greek χυ-, in χέω, χῦμα, Sanscrit root hu, ‘to sacrifice’). See also Götze.
