Pronunciation

  • US: /ˈɹeɪdɚ/[1]

Etymology

It is formed from English raid + -er.[2][3][4] The verb raid (from 1848 in the OED, 1864 in Etymonline) comes from the noun,[2][4] which began as a Scots and northern form of road, from Old English rād (“riding, journey, hostile incursion”),[4][2] from Proto-Germanic *raidō (“a ride”), related to ride.[4][1] Etymonline notes that the noun fell into obscurity in the 17th century and was revived by Walter Scott in “The Lay of the Last Minstrel” (1805) and “Rob Roy” (1818).[4]

Earliest recorded meaning

A person who takes part in a hostile, predatory incursion; a marauder: 1861, in the North American Review.[2] Merriam-Webster also has 1861,[5] while Etymonline dates the word to 1863 and calls it a word of the American Civil War.[4]

Semantic evolution

The word was first used of men on raids in wartime.[2][4] In the early 20th century, as raids came to be made from the air, it was also applied to an aircraft on a bombing operation, in H. G. Wells's The War in the Air (1908).[2][5] Merriam-Webster also records it for a fast, lightly armed ship used to attack merchant shipping (a commerce raider) and for a member of a unit trained for close-range fighting, like a commando.[5] On the stock market, from 1972, a raider is a person who makes an aggressive attack on shares or a company, especially a corporate raider attempting a hostile takeover.[2][5]
