An Etymological Dictionary of the German Language/Annotated/kasteien

by Friedrich Kluge

kasteien, verb, ‘to chastise,’ from Middle High German kastîgen (g for j), kę̂stigen, Old High German chęstîgôn, ‘to chastise, punish’; the alteration of the accent and the vowels corresponds to that in Kastanie (which see) compared with the dialectic Keste. Latin castîgare (whence also French châtier, and further English chastise) was adopted on the introduction of Christianity (compare Kreuz, Priester, and predigen) from ecclesiastical Latin; Old High German chę̂stîgôn, like many words borrowed in the Old High German period (see predigen), was accented after the German method.
