heteronomous

The word 'heteronomous' is a compound formed from Greek elements. The first part, hetero-, originates from the Proto-Indo-European root sem- meaning "one, as one," which developed a comparative form leading to the Greek sense of "the other of two." The second part, -nomos, derives from the Greek verb nemein, meaning "to deal out, manage, pasture," which evolved to signify "custom, law." This root is distantly related to the English word 'number' through the PIE root nem- meaning "to assign, allot." Literally meaning "subject to another's law," the term entered English in the early 19th century via German philosophy (heteronom), specifically to describe moral or political dependence, contrasting with 'autonomous.' Its biological sense, describing parts governed by different laws of growth, followed shortly after, maintaining the core logic of being governed by an external or differing principle.
