An Etymological Dictionary of the German Language/anbeischig

by Friedrich Kluge

anbeischig, adj., from the equiv. MidHG. antheiȥec, antheiȥe. adj., ‘bound, engaged,’ influenced by hetschen; the MidHG. adj. is derived from MidHG. and OHG. an-theiȥ, ‘vow, promise,’ which, like Goth. andahait ‘confession,’ AS. ondettan, ‘to confess,’ is compound of the particle ant- and the root hait, ‘to bid.’
