DenveryoudaoicibaDictYouDict[Denver 词源字典]
city in Colorado, U.S., founded 1858 as Auraria ("golden"), renamed 1859 for Gen. James W. Denver (1817-1892), governor of the territory. The family name is from the place of that name in Norfolk, literally "ford or passage used by the Danes," from Old English Dena (genitive plural) + fær.

The Denver boot or shoe as the name for a wheel clamp for illegally parked vehicles, supposedly was invented 1953 by Frank Marugg, pattern-maker and violinist with the Denver Symphony Orchestra. He was a friend of politicians and police department officials, and the city sheriff's department came to him for help in making a device to immobilize vehicles whose owners didn't pay parking tickets.[Denver etymology, Denver origin, 英语词源]
