raceway

Etymology

It is a compound from English race + way.^{[2][3][4][5][6]} The first element is race in its sense of a swift current of water, or the channel that carries it;^[4][2] that word goes back to an early Scandinavian source, compare Old Norse rás (“a running, a rush of water”).^[4][2] The OED compares racecourse, and for the sense "racetrack" also racetrack;^[2] Etymonline takes that sense from race in its sense of a contest of speed.^[4]

Earliest recorded meaning

A channel in which water runs, especially to or from a mill: 1793, in the diary of J. MacDonell.^[2][3] Etymonline dates the word to 1828,^[4] as does Merriam-Webster's Collegiate,^[7] and Dictionary.com to 1820–30.^[6]

Semantic evolution

The word began as an American term for a millrace or canal; the Shorter Oxford marks it as chiefly American.^[5][2] From the 1870s it was used for an artificial channel of running water in which fish are reared.^[2][3] Its idea of a confined course for something moving was carried into machinery: a passage for a weaver's shuttle (1849), a groove along which type moves in a typesetting machine (1875) and the groove in which the balls or rollers of a bearing run (1946).^[2] Since 1896 it has also named a pipe or channel that holds electrical wires.^[2][3] The sense "racetrack", especially one for harness racing, is recorded from 1910,^[2] and Etymonline finds it of a motor-racing course by 1936.^[4]
