An Etymological Dictionary of the German Language/Lende
Lende, f., ‘loins,’ from the equiv. MidHG. lęnde, OHG. lęntin, f.; corresponding to Du. lende, AS. lęnden, f. (in the plur. lęndenu, m.); OIc. lend, Dan. lynd, ‘loins’ (allied to Ic. lundir, ‘sirloin, saddle of mutton’?); in Goth. perhaps *landini, f. In case the b of Lat. lumbus, ‘loins,’ represented Aryan dh, or rather dhw (for Lat. barba, representing bhardhâ, see Bart, and Lat. ruber, representing Aryan rudhros, ἐρυθρός, see rot), HG. Lende might be compared with it. The prim. form lndhwî- is also indicated by OSlov. lędvija, f., ‘loins, kidney.’
