The word regulator traces back to Latin regula (rule), reflecting the concept of imposing order or control. The suffix -ator transforms it into an agent noun, originally describing a person who enforces rules (e.g., a governor) and later extending to mechanical devices that maintain stability (18th century). The evolution mirrors societal shifts from human oversight to automated systems.
