An Etymological Dictionary of the German Language/Annotated/Spund

by Friedrich Kluge

Spund, masculine, ‘bung, bunghole, channel,’ from Middle High German spunt (genitive spuntes), masculine, ‘bunghole, valve in the tube of a pump.’ The persistent t of the Middle High German inflected form points of itself to the foreign origin of the term, and still more so the Middle High German variants punct and pfunt, as well as Modern High German (dialectic) Punt and Bunde (as to the period when the word was borrowed, compare Wein). Dutch spon, spun, ‘bung,’ and French bonde, ‘sluice, plug,’ bondon, ‘bung,’ are corresponding terms, derived from the Middle High German words, which are based on Latin puncta, ‘prick, puncture, opening made inn pipe.’ With regard to the s of Middle High German spunt, compare Italian spuntone, ‘spontoon,’ spuntare, ‘to blunt, allied to Latin punctum.
