An Etymological Dictionary of the German Language/quitt

by Friedrich Kluge

quitt, adj., ‘quit, rid,’ from MidHG. quī̆t, ‘released, unencumbered, free’; borrowed about 1200 A.D. from the equiv. Fr. quitte, whence also Du. kwijt, E. quit (also E. quite); Fr. quitte and quitter, ‘to let go, forsake,’ are derived from Lat. quietare.
