An Etymological Dictionary of the German Language/Annotated/stören

by Friedrich Kluge

stören, verb, ‘to stir up, disturb, poke, rake,’ from Middle High German stœren, Old High German stôren (stôrren from *stôrjan, *staurjan), weak verb, ‘to scatter, destroy, annihilate’; to these are allied North Frisian stiaren, and with gradation Anglo-Saxon styrian, English to stir, but hardly the cognates of streuen. The early history is obscure.
