An Etymological Dictionary of the German Language/Annotated/Schemel
Schemel, masculine, ‘stool, footstool,’ from the equivalent Middle High German schęmel, schamel (schâmel?), masculine; Old High German scamal (scâmal?), masculine, which, like Old Saxon fôtscamel, ‘footstool,’ and Anglo-Saxon sčęǫmul (especially fôt-sčęǫmul), masculine, is derived from Latin scamellum. Dutch schabel, ‘stool,’ as well as the equivalent Romance terms, French escabelle, escabeau, and Italian sgabello, is based on Latin scabellum; hence in Middle Rhenish Schawéll, Schabéll.
