An Etymological Dictionary of the German Language/reden

by Friedrich Kluge

reden, vb., ‘to speak, talk, converse,’ from the equiv. MidHG. ręden, OHG. rędiôn, rędôn, also OHG. rędinôn, just as in the case of OHG. rędia the equiv. variant rędina occurs (comp. OSax. ręðion, ‘to speak’); from this OHG. rędinôn, is derived OHG. rędinâri, MidHG. rędenœre, ModHG. Redner, ‘orator.’
