An Etymological Dictionary of the German Language/stören
Appearance
stören, vb., ‘to stir up, disturb, poke, rake,’ from MidHG. stœren, OHG. stôren (stôrren from *stôrjan, *staurjan), wk. vb., ‘to scatter, destroy, annihilate’; to these are allied North Fris. stiaren, and with gradation AS. styrian, E. to stir, but hardly the cognates of streuen. The early history is obscure.
