An Etymological Dictionary of the German Language/genug
genug, adj., ‘enough, sufficient,’ from the corresponding MidHG. genuoc(g), OHG. ginuog; a common Teut. adj. with the ModHG. meaning; comp. Goth. ganôhs, AS. genôh, E. enough, Du. genoeg, OSax. ginôg; a deriv. of an OTeut. pret.-pres. Goth. ganah, OHG. ginah, ‘it suffices’; comp. Goth. ganaúha, ‘sufficiency,’ OHG. ginuht, MidHG. genuht, ‘sufficiency.’ On MidHG. genuhtsam, OHG. ginuhtsam, ‘abundant, sufficient,’ is based ModHG. genugsam. To the Teut. root nō̆h (Aryan nū̆k) preserved in these words some refer the Sans. root naç, ‘to attain,’ and Lat. nancisci.
