An Etymological Dictionary of the German Language/bequem
bequem, adj., ‘convenient, comfortable,’ from MidHG. bequœ̂me, OHG. biquâmi, ‘suitable, fit.’ Akin to AS. gecwême, MidE. îcwême, cwême, ‘agreeable, suitable’; qêmi-, the base, is a verbal adj. from Goth. qiman, OHG. chuman, ‘to come,’ for which the meaning ‘to be fitting, to suit,’ already existing in Goth. gaqimiþ, ‘it is fitting,’ is presupposed; comp. AS. becuman, E. become. See kommen and Lat. convenire, ‘to fit in with, be becoming, suit,’ which is primit. allied.
