What does regulated mean?
Regulated describes something that is controlled, directed, or managed according to rules, laws, standards, or established procedures. It is especially common when discussing industries, professions, financial activity, environmental conditions, and government oversight: a regulated market, a regulated profession, or a tightly regulated process. The word can also suggest order and consistency, implying that activity is checked, standardized, or kept within prescribed limits. As the past tense and past participle of regulate, it describes an authority exercising control over something. Its history comes from the Latin regulare, meaning “to rule” or “to direct according to a rule,” itself connected with regula, “rule” or “standard.” Regulated is consequently useful for describing systems and practices that are deliberately brought under control rather than allowed to proceed without supervision.
Controlled, managed, or governed according to rules, regulations, or established standards.

Where does regulated come from?
Regulated comes from regulate, which was borrowed from Latin regulare, “to rule, direct, or make orderly.” The Latin verb derives from regula, meaning “rule” or “standard,” ultimately related to regere, “to rule” or “direct.” The English form developed as a verb and as an adjective and past participle through the ordinary English process of adding inflectional endings.
