urban:  Urban comes from Latin urbānus, a derivative of urbs ‘city’ (a word of unknown origin). It was preceded into English by urbane , which is essentially the same word, but came via Old French urbaine. It was originally used as urban is now, but after urban arrived it gradually took the metaphorical path to ‘smooth, sophisticated’. The derivatives suburb and suburban date from the 14th and 17th centuries respectively; and suburbia was coined in the 1890s. => suburban, urbane
"characteristic of city life, pertaining to cities or towns," 1610s (but rare before 1830s), from Latin urbanus "of or pertaining to a city or city life; in Rome," also "in city fashion, polished, refined, cultivated, courteous," but also sometimes "witty, facetious, bold, impudent;" as a noun, "city dweller," from urbs (genitive urbis) "city, walled town," of unknown origin.
The word gradually emerged in this sense as urbane became restricted to manners and styles of expression. In late 20c. American English gradually acquiring a suggestion of "African-American." Urban renewal, euphemistic for "slum clearance," is attested from 1955, American English. Urban sprawl recorded by 1958. Urban legend attested by 1980.
