An Etymological Dictionary of the German Language/Tenne

by Friedrich Kluge

Tenne, f., ‘threshing-floor,’ from the equiv. MidHG. tęnne, n., f., and m., OHG. tęnni, n. No corresponding word occurs in this sense in the allied Teut. dialects. It has been connected with AS. dęnu, ‘valley,’ AS. and E. den; but Tenne is rather a derivative of Tanne (lit. ‘made of fir’).
