Appearance
Bogen, masculine, ‘bow, arc, vault, sheet (of paper),’ from Middle High German boge, Old High German bogo, masculine, ‘bow’; compare Anglo-Saxon boga, English bow; Gothic *buga. Properly a derivative of biegen, hence originally ‘curve, bend,’ connected with the equivalent cognates of Bucht; compare further the primitively Teutonic compounds Ellenbogen, Regenbogen.
