Pronunciation

  • IPA: UK /ˈməʊ.tə/, US /ˈmoʊ.t̬ɚ/[1]

Etymology

It is inherited from Middle English motour, borrowed from Latin mōtor (“mover”),[2][3] an agent noun from mōtus, the past participle of movēre “to move”,[3][4] from Proto-Indo-European *meue- (“to push away”).[3] It is related to move, motion and motive.[2][5]

Earliest recorded meaning

A controller or prime mover, in reference to God: 1447 in Barnhart,[2] the mid-15th century in Etymonline.[3] In early use a motor was one who imparted motion.[5]

Semantic evolution

The part that starts motion in a mechanism is from 1586,[6][4] and an agent or force that produces mechanical motion from 1644 in the OED and 1664 in Barnhart.[6][2] A machine that supplies motive power is from 1856, in Emerson,[2][3] and the main modern sense dates from the mid-19th century.[5] The adjective, causing motion, is from 1823–1824,[4][2] and is used of nerves that carry impulses to the muscles.[7] With the automobile the word became short for motor car (1895), and the verb, to travel by car, is from 1896–1897.[2][3] Motorcycle is from 1896, motorist from 1896 in the OED, motorcade from 1913, on the model of cavalcade,[2] and motormouth from 1970.[3]
