chasten (verb) - to correct through discipline, criticism, or punishment; to point out error or failure [chey-suhn]
chastise means to severely punish, censure, or discipline; to castigate
BREAKDOWN: The words chasten and chastise, similar in meaning but different in intensity, both derive from an Old French word chastiier meaning to punish. Two possible roots for these words are CAST- meaning pure and CAS- meaning to cut.
“Nothing chastens a planner more than the knowledge that he will have to carry out the plan.” —James M. Gavin
