An Etymological Dictionary of the German Language/tauchen

by Friedrich Kluge

tauchen, vb., ‘to dip, dive,’ from the equiv. MidHG. tûcken, wk. vb., OHG. tûhhan, str. vb.; comp. Du. duiken, ‘to dive, duck,’ E. to duck (whence also E. duck, AS. dûce); see further ducken. Other terms derived from the Teut. root duk, ‘to stoop, dive,’ are wanting. The connection of the word with taufen is improbable.
