What does regulator mean?
A regulator is something that controls, monitors, or adjusts a process, institution, or system. The word most often describes an official or public body responsible for enforcing rules: a financial regulator supervises banks, while a market regulator oversees competition and consumer protection. It can also name a device, such as a pressure regulator, that keeps a physical quantity within safe or consistent limits. In its verbal form, regulate means to control something according to a rule, standard, or principle, as in regulating emissions or regulating access to a service. The term is especially common in legal, governmental, financial, and technical contexts. Its defining feature is systematic control: unlike a simple recommendation or observation, regulation establishes limits, checks compliance, or adjusts a process toward a specified condition.
A person, organization, or device that controls, supervises, or adjusts something according to rules, standards, or practical limits.
"The environmental regulator issued a warning to the company."

Where does regulator come from?
The word comes from Latin regulare, meaning “to rule” or “to direct according to a rule,” from regula, “rule” or “ruler.” English borrowed the form in the late 15th and 16th centuries, initially in the sense of governing or directing according to a rule. Its development reflects the same idea found in related forms such as rule, regular, regulation, and regulatory, all of which share a Latin heritage.
