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.
