From Middle English dowle, dule, of uncertain origin. Perhaps from Old French doelle (“the hollow part of a tool where the handle is”), from Frankish *duli (“hollow tube, pipe”), from Proto-Germanic *dulją (“pipe”), from Proto-Indo-European *dʰel- (“curvature, hollow”). If so, then cognate with French douelle, douille. Alternatively from Middle Low German dövel (“peg, plug”), from Old Saxon *dubil, from Proto-Germanic *dubilaz. If so, then cognate with Dutch deuvel (“wooden peg”), German Dübel (“dowel”).
