英語の語源
raid
raid: [15] Raid and road are doublets – that is to say, they have a common ancestor, but have diverged over the centuries. In this case the ancestor was Old English rād ‘riding’, hence ‘hostile incursion on horse-back’, a relative of ride. South of the border this developed to road, and lost its predatory connotations (although they are preserved in inroads), but in Scottish English it became raid. This had more or less died out by the end of the 16th century, but Sir Walter Scott revived it at the beginning of the 19th century, and it has gone from strength to strength ever since. => ride, road
raid (n.)
early 15c., "mounted military expedition," Scottish and northern English form of rade "a riding, journey," from Old English rad "a riding, ride, expedition, journey; raid," (see road). The word died out by 17c., but was revived by Scott ("The Lay of the Last Minstrel," 1805), ("Rob Roy," 1818), with extended sense of "attack, foray."
raid (v.)
"take part in a raid," 1785 (implied in raiding), from raid (n.). Related: Raided; raiding. Also see raider.
