Castigation

Castigation (from the Latin castigatio) or chastisement (via the French châtiment) is the infliction of severe (moral or corporal) punishment. One who administers a castigation is a castigator or chastiser.

In earlier times, castigation specifically meant restoring one to a religiously pure state, called chastity. In ancient Rome, it was also a term for the magistrate called a censor (in the original sense, rather than the later politicized evolution), who castigated in the name of the pagan state religion but with the authority of the 'pious' state.
