An Etymological Dictionary of the German Language/Annotated/Trog

by Friedrich Kluge

Trog, masculine, ‘trough,’ from the equivalent Middle High German and Old High German troc (g), masculine; compare Dutch trog, Anglo-Saxon trog, English trough, Old Icelandic trog. The assumed Teutonic trogo-, from which the cognate Italian truogo, ‘trough,’ is borrowed, is based on pre-Teutonic dru-kó-, which is rightly connected with the Aryan stem dru (dreu, deru), ‘tree, wood,’ discussed under Teer; compare Sanscrit dru, dâru, ‘wood.’ Hence Trog is literally ‘wooden article.’
