Sense: adjective/1
Penal is a formal adjective mostly used in legal or policy language. It points to punishment as part of a system, so penal code, penal reform, and penal institution are typical uses. Punitive is closer to meaning meant to punish, and it often suggests severity or an effort to stop future bad behavior. Criminal usually connects with crime, criminals, or criminal law, not with punishment itself. Disciplinary is used for punishment inside schools, workplaces, or sports bodies, outside the court system. A prison officer may work in a penal institution, a court may award punitive damages, and a teacher may take disciplinary action against a student.
Etymology
Penal entered English through French and Late Latin words built on the Latin noun poena, meaning punishment or penalty. The same word family also produced penalty and penalize. Farther back, Latin poena came from Greek poinē, a word for a payment or punishment for a wrong.
