An Etymological Dictionary of the German Language/Schall
Appearance
Schall, m., ‘loud sound, noise,’ from the equiv. MidHG. schal (gen. schalles), OHG. scal (ll), m.; from this is derived MidHG. and ModHG. schallen, akin to OHG. scëllan, MidHG. schëllen, ‘to sound loudly, resound,’ OIc. skjalla, ‘to rattle.’ From the Teut. verb is derived the Rom. term Ital. squillare, ‘to ring, resound.’ See Schelle and Schilling.
