An Etymological Dictionary of the German Language/Bohne

by Friedrich Kluge

Bohne, f., ‘bean,’ from MidHG. bône, OHG. bôna, f.; the corresponding AS. beán, E. bean, Du. boon, OIc. baun, have the same meaning. The early existence of this word is attested by the name of the Fris. islands, Baunonia. It has not yet been possible to find a connecting link between the primit. Teut. term and the equiv. Lat. faba, OSlov. bobŭ (Gr. φακός, ‘lentil’).
