An Etymological Dictionary of the German Language/Schinden
Schinden, vb., ‘to skin, flay,’ from MidHG. schinden, ‘to skin, peel, ill-treat severely,’ OHG. scintan; a denominative from a lost OHG. *scind, n., ‘hide, skin,’ which may be assumed in OHG. from OIc. skinn (see Schinne), n., ‘skin, hide, fur, leather.’ E. skin, from MidE. skinne (AS. scinn), is borrowed from Scand., since AS. sci, sči, must have become shi in ModE. Goth. *skinþa-, from pre-Teut. skénto-, has not yet been found in the non-Teut. languages.
