autonomous

The word 'autonomous' is a direct borrowing from the Greek autonomos, meaning "having its own laws." It is composed of autos ("self") and nomos ("law"). This concept was central to ancient Greek political thought, describing a city-state that governed itself by its own statutes rather than being subject to an external power. The term entered English in the early 19th century, initially in political and philosophical contexts, before its meaning broadened to encompass independence in general and, more recently, the self-directing capability of technological systems.
