Mi Webster's ha le sequente pro "thunder": 1. thunder n [ME thoner, thunder, fr. OE thunor; akin to OHG thonar thunder, L tonare to thunder] Il non es evidente a me si le latino L. tonare veni del germanic o es solmente un cognate indoeuropee. Listate sub le parola "tone" (tono) in mi Webster's es: 1. tone n [ME, fr. L tonus tension, tone, fr.
