An Etymological Dictionary of the German Language/Annotated/Stolle

by Friedrich Kluge

Stolle, feminine, Stollen, masculine, ‘prop, post, gallery (of a mine),’ from Middle High German stolle, Old High German stollo, masculine, ‘support, post.’ Derived, like Stall, stellen, and still, from the root stal, which appears also in Sanscrit sthûṇâ. The latter points, like Old High German stollo (from *stolno-), to Aryan stelnâ, ‘post’; for ll from ln compare voll and Wolle.
