An Etymological Dictionary of the German Language/wir

by Friedrich Kluge

wir, pron., ‘we,’ from the equiv. MidHG. and OHG. wir; corresponding to Goth. weis, OSax. wî, Du. wij, AS. wê, E. we. The common Teut. wîz, with a secondary nomin. suffix s, is based on Aryan wei, whence Sans. vayám, ‘we.’ The declension of wir, which is supplemented by uns, belongs to grammar.
