An Etymological Dictionary of the German Language/Zuck
Zuck, m., ‘twitch, start, shrug,’ from MidHG. zuc (gen. zuckes), m., ‘quick marching, jerk.’ Allied to zucken, zücken, vb., ‘to move convulsively, start, jerk, tug,’ from MidHG. zucken, zücken, OHG. zucchen, zukken, ‘to march quickly, snatch away, jerk, tug’; intensive form of ziehen. Hence the ModHG. compounds entzücken, verzücken (MidHG. enzücken, verzücken), signified orig. ‘to snatch away, transport in spirit.’ From the base tukkôn is derived Fr. toucher, Ital. toccare.
