Meaning

noun a cut pile fabric with vertical ribs; usually made of cotton

noun a road made of logs laid crosswise

verb build (a road) from logs laid side by side

originOrigin uncertain. Probably from cord + duroy (“a 17th century coarse fabric made in England”). Probably not from French *corde du roi (“cloth of the king”), which is unattested in French, where the term for the corduroy is velours côtelé. Possibly from cordesoy from corde de soie (“rope of silk or silk-like fabric”), named for example in a 1756 advertisement for clothing fabrics; see Wikipedia…
