An Etymological Dictionary of the German Language/Annotated/Schimmer
Schimmer, masculine, ‘glimmer,’ early Modern High German, formed from Low German and Dutch schemeren, ‘to glimmer, gleam.’ This is connected, like Middle High German schîme, ‘glimmer, lustre,’ Old High German scîmo, Gothic skeima, ‘light, lamp,’ with the root skī̆, ‘to shine, glitter’; compare Middle English schimeren, ‘to shimmer,’ English shimmer, English shim, ‘white spot,’ Swedish skimra (see Schemen).
