Pronunciation

  • UK: /kɪˈnɛtɪk/[1]
  • US: /kɪˈnɛtɪk/, /kaɪˈnɛtɪk/[1]

Etymology

It is borrowed from Ancient Greek κινητικός (kīnētikós, “moving, putting in motion”),[2][3][4][5][6][7] from κινητός (kīnētós, “moved”), the verbal adjective of κινέω (kīnéō, “to move”).[3][5][8][9] Etymonline traces the verb to Proto-Indo-European *keie- (“to set in motion”).[3] Klein compares Latin cieō (“to put in motion”) and citō (“to put into quick motion”),[8] the Latin source of excite, incite and recite.[10] A noun from the same Greek verb, κίνημα (kínēma, “movement”), is the source of cinema.[10][11]

Earliest recorded meaning

Relating to muscular motion: 1841, according to Etymonline.[3] The OED's first record, from 1855 in Mayne's Expository Lexicon of Medical Science, has the rare sense "producing or causing motion".[2]

Semantic evolution

The general sense "of or relating to motion, due to motion" is recorded from 1864,[2][4][9] and kinetic energy, the energy a body has because it moves, from 1870.[4][12] From 1873 kinetic was also a noun for the science of motion, now kinetics.[2] Specialist senses followed in chemistry (1882), for the kinetics of a reaction, in cytology (1894), for cells dividing, in biology (1905) and in phonetics (1931).[2] The figurative sense "active, dynamic, full of energy" is first found in H. G. Wells in 1931,[2][6] and kinetic art, which depends on movement for its effect, from 1957.[2]
