An Etymological Dictionary of the German Language/Annotated/tauchen
Appearance
tauchen, verb, ‘to dip, dive,’ from the equivalent Middle High German tûcken, weak verb, Old High German tûhhan, strong verb; compare Dutch duiken, ‘to dive, duck,’ English to duck (whence also English duck, Anglo-Saxon dûce); see further ducken. Other terms derived from the Teutonic root duk, ‘to stoop, dive,’ are wanting. The connection of the word with taufen is improbable.
