What does penal mean?
Penal is a formal adjective meaning relating to punishment, especially punishment imposed under criminal law. It is most commonly encountered in the expression “penal code,” which refers to a legal system defining criminal offences and the punishments associated with them. The adjective can also describe something punishable, although in that sense “punishable” is often clearer and more natural. In contemporary English, “penal” is unusual in everyday conversation, which tends to use “punitive” when describing a measure intended to punish or “criminal” when referring to an offence. Its restricted use does not make it obscure: it remains readily understood in legal, historical, and institutional contexts. The word is especially useful when discussing the relationship between law and punishment or when distinguishing the formal legal concept of a penalty from a more general idea of retribution.
Relating to punishment imposed by law, especially as a system of rules or penalties.
"The court reviewed the penal provisions of the relevant legislation."
Most often used in the established expression “penal code”; elsewhere it sounds formal and somewhat dated.
Subject to legal punishment; punishable.
"The judge considered whether the offence was penal in nature."
This sense is less common than the relation-to-punishment sense; “punishable” may be preferable in modern usage.
In everyday legal language, “penal code” has survived as a standard phrase, giving this formal adjective a familiar place in the vocabulary of law.

Where does penal come from?
Penal entered English in the early 19th century from Latin poenalis, meaning “of or relating to punishment.” The Latin adjective was formed from poena, “punishment” or “penalty,” which was borrowed from Greek poinē, a term for suffering, penalty, or the price paid for an offence. The same broad Indo-European root also lies behind English words such as pain and punish.
How penal is actually used
This is a formal and comparatively uncommon word. Outside the established phrase “penal code,” native speakers usually prefer “punitive,” “punishable,” or “relating to punishment.”
