An Etymological Dictionary of the German Language/predigen

by Friedrich Kluge

predigen, vb., ‘to preach,’ from the equiv. MidHG. prędigen, brędigen, OHG. prędigôn, brędigôn (brêdiôn); corresponding to OSax. prędigôn, Du. prediken. Borrowed in the OHG. period from the ecclesiastical Lat. and Rom. prœdicâre (Fr. prêcher, whence E. preach, Ital. predicare), from which OIr. pridchim, ‘I preach,’ is also derived. —
