An Etymological Dictionary of the German Language/Annotated/Weck

by Friedrich Kluge

Weck, masculine, ‘wedge-shaped fine bread,’ from Middle High German węcke, Old High German węcki (from węggi), masculine, ‘wedge, wedge-shaped bread,’ corresponding to Dutch weg, ‘fine white bread,’ Anglo-Saxon węcǧ, English wedge, and the equivalent Old Icelandic veggr. Teutonic wagjo-, from pre-Teutonic waghyo-, is usually regarded as primitively cognate with Lithuanian vagis, ‘wedge, plug.’ For the terms applied to pastry compare Kipfel and Krapfe.
