An Etymological Dictionary of the German Language/kreischen

by Friedrich Kluge

kreischen, vb., ‘to shriek,’ from MidHG. krîschen, ‘to screech, shriek’; OHG. *chrîskan and Goth. *kreiskan are wanting. MidHG. krîȥen, ‘to shriek’ (Goth. *kreitan), points to the fact that a dental (Goth. t) has been lost before the suffix sk of kreischen, just as a guttural has been dropped in forschen, OHG. forskôn. Comp. Du. krijschen, ‘to shriek, yell’ Comp. kreisen.
