Etymology Origin:
Derived from Latin regulare ("to direct by rule"), itself from regula ("rule"). The root reflects the idea of straightening or guiding, akin to using a ruler (literally a "straight stick") to measure or align. Over time, "regulate" expanded from physical alignment (e.g., machinery) to abstract control (e.g., laws or biological functions).
