Pronunciation

  • IPA: /ɔːˈtɒnəməs/ (UK); /ɔˈtɑnəməs/, /ɑˈtɑnəməs/ (US)[1]

Etymology

It is formed from Ancient Greek αὐτόνομος (autónomos, “having its own laws”) and -ous,[2][3][4] from αὐτός (autós, “self”) and νόμος (nómos, “law”) (see autonomy),[2][3] from Proto-Indo-European *nem- (“to assign, allot”).[2] Of animals the Greek word meant feeding or ranging at will.[2]

Earliest recorded meaning

Subject to its own laws: 1777, in translations of Montesquieu, in Etymonline;[2] Merriam-Webster dates it to 1799, and the OED's first quotation, relating to an autonomy, to 1800.[3][5]

Semantic evolution

Self-governing, independent, is from 1804,[5] and in biology an independent organism from 1861.[5] It has been used mostly in metaphysics and politics,[2] and in Kant's philosophy of a will that gives itself its own law.[6] Machines that operate without human control, as autonomous vehicles, are a recent use of the sense independent.[7]
