An Etymological Dictionary of the German Language/Annotated/Quirl
Quirl, masculine, ‘whisk, twirling stick,’ from the equivalent Middle High German twirel, twirl!, Old High German dwiril, ‘stirring stick’; akin to Middle High German twërn, Old High German dwëran, ‘to turn, stir’; allied to the equivalent Old Icelandic substantive þvara. With the Teutonic root þwer (Aryan twer), are connected Greek τορύνη, and Latin trua, ‘stirring spoon.’ It is doubtful whether Quark is allied.
