An Etymological Dictionary of the German Language/Zwirn

by Friedrich Kluge

Zwirn, m., ‘thread, twine, twisted yarn,’ from MidHG. zwirn, m., ‘double thread’; like AS. twîn, E. twine, Du. twijn (Dan. tvinde, ‘twine wheel’), it points to a base twizna-. A Teut. root twis appears also by a different derivation in E. twist. —
