What does prohibitor mean?
A prohibitor is someone who prevents or forbids an action, often an official whose authority derives from a law, regulation, or formal policy. The word emphasizes the person or institution doing the prohibiting rather than the prohibition itself. It can be used in legal, governmental, regulatory, and institutional settings, although the more familiar term for the restriction itself is usually prohibition. In general discussion, prohibitor can sound formal and somewhat uncommon, so alternatives such as regulator, authority, or the context-specific title of an official may sound more natural. Its usefulness lies in distinguishing the enforcing agent from the rule or principle that the agent represents. The term is related to a family of English words built from Latin prohibere, “to forbid,” including prohibit, prohibition, prohibitive, and prohibitory.

Where does prohibitor come from?
The word comes from Latin prohibere, formed from pro- and habere, with the sense “to hold back” and hence “to forbid.” Latin developed an agent-noun form corresponding to one who prohibits, which was adopted into English in the language’s legal and institutional vocabulary. English cognates such as prohibit, prohibition, prohibitive, and prohibitory all reflect this same Latin root.
How prohibitor is actually used
Uncommon and more typical of formal, legal, or institutional contexts than of everyday speech. It is less common than the abstract noun meaning a rule or act that forbids something.
