corduroyyoudaoicibaDictYouDict[corduroy 词源字典]
corduroy: [18] Popular etymology usually associates corduroy with a supposed French corde du roy ‘cord of the king’ or even couleur du roy ‘king’s colour’ (the original corduroy having according to this theory been purple), but in fact there is no concrete evidence to substantiate this. A more likely explanation is that the word’s first syllable represents cord in the sense ‘ribbed fabric’, and that the second element is the now obsolete noun duroy ‘coarse woollen fabric’ [17], of unknown origin.

destroyyoudaoicibaDictYouDict
destroy: [13] As in the case of demolish, to destroy something is almost literally to ‘unbuild’ it. The word comes via Old French destruire from *dēstrūgere, a Vulgar Latin alteration of Latin dēstrūere. This was a compound verb formed from the prefix -, denoting reversal of a previous state, and strūere ‘pile up, build’ (source of English construct and structure). Its past participle, dēstructus, has produced English destruction [14], destructive [15], and the verb destruct (recorded once in the 17th century but revived in the 1950s by backformation from destruction).

royalyoudaoicibaDictYouDict
royal: [14] Royal and regal are ultimately the same word. Both go back to the Latin adjective rēgālis, a derivative of rēx ‘king’. But whereas regal was probably borrowed direct from Latin, royal was acquired via Old French, where rēgālis became roial.

arroyo (n.)youdaoicibaDictYouDict
"watercourse, dry streambed," 1845, a California word, from American Spanish, in Spanish, "rivulet, small stream," from Latin arrugia "shaft or pit in a gold mine," apparently a compound of ad- "to" (see ad-) + ruga "a wrinkle" (see rough (adj.)).
corduroy (n.)youdaoicibaDictYouDict
1780, probably from cord + obsolete 17c. duroy, name of a coarse fabric made in England, which is of unknown origin. Folk etymology is from *corde du roi "the king's cord," but this is not attested in French, where the term for the cloth was velours à côtes. Applied in U.S. to a road of logs across swampy ground (1780s) on similarity of appearance.
CORDUROY ROAD. A road or causeway constructed with logs laid together over swamps or marshy places. When properly finished earth is thrown between them by which the road is made smooth; but in newly settled parts of the United States they are often left uncovered, and hence are extremely rough and bad to pass over with a carriage. Sometimes they extend many miles. They derive their name from their resemblance to a species of ribbed velvet, called corduroy. [Bartlett]

Battle royal (1670s) preserves the French custom of putting the adjective after the noun (as in attorney general); the sense of the adjective here is "on a grand scale" (compare pair-royal "three of a kind in cards or dice," c. 1600).
