An Etymological Dictionary of the German Language/Annotated/kreischen
kreischen, verb, ‘to shriek,’ from Middle High German krîschen, ‘to screech, shriek’; Old High German *chrîskan and Gothic *kreiskan are wanting. Middle High German krîȥen, ‘to shriek’ (Gothic *kreitan), points to the fact that a dental (Gothic t) has been lost before the suffix sk of kreischen, just as a guttural has been dropped in forschen, Old High German forskôn. Compare Dutch krijschen, ‘to shriek, yell’ Compare kreisen.
