Etymology Origin:
The word "base" traces back to the Old French bas, meaning "low," which itself derives from the Latin basis (foundation, pedestal) and Greek basis (step, pedestal). The sense of "low" evolved metaphorically into "foundation" (the lowest supporting part) and later into "moral lowliness" (14th c.). The modern meanings—physical foundation, operational center, and ethical judgment—all stem from this core idea of "bottom" or "support."
