spotter

Etymology

It is formed from English spot + -er, an agent noun from the verb spot.^[2][3][4][5]

Earliest recorded meaning

A person who stains or soils something, or who puts decorative spots on something: 1611, in Cotgrave's French–English dictionary.^[2] Etymonline likewise dates "one who makes spots" to the 1610s, and Merriam-Webster gives 1611.^[3][6]

Semantic evolution

Johnson (1755) defined the word only as "one that spots; one that maculates".^[7] The later senses come from the verb in its sense "to catch sight of, pick out".^[3] From 1850 a spotter was a lookout, especially for criminals.^[2] From 1867, chiefly in North America, it was also a person hired to watch employees for dishonesty.^[2] Green's Dictionary of Slang records it for a detective from 1876,^[8][3] and the American Heritage Dictionary still lists the bank and company spy.^[9] In target shooting a spotter noted where each shot struck (1875).^[2] Military use began in 1904 with a person locating an enemy target for the gunners, and in 1931 for a watcher who identifies aircraft;^[2] Collins mentions such watchers in civil defence.^[10] In the 20th century the word was applied to anyone who looks for or identifies something (1913), to a talent scout (1935), to a hobbyist who notes trains or other vehicles (1944, British) and to a person who guards a gymnast or weightlifter against accidents (1937).^[2][4][10] Green's Dictionary of Slang also records a British sense from 1998, an insignificant weakling, from the stereotype of the trainspotter.^[8]
