An Etymological Dictionary of the German Language/kasteien

by Friedrich Kluge

kasteien, vb., ‘to chastise,’ from MidHG. kastîgen (g for j), kę̂stigen, OHG. chęstîgôn, ‘to chastise, punish’; the alteration of the accent and the vowels corresponds to that in Kastanie (which see) compared with the dial. Keste. Lat. castîgare (whence also Fr. châtier, and further E. chastise) was adopted on the introduction of Christianity (comp. Kreuz, Priester, and predigen) from ecclesiastical Lat.; OHG. chę̂stîgôn, like many words borrowed in the OHG. period (see predigen), was accented after the G. method.
