Urban describes something to do with cities and towns, as opposed to the countryside. Urbane describes a person's manner: refined, courteous, and sophisticated. Both come from the same Latin root for city, urbs, but only urbane kept the sense of city polish.
The core difference
Urban relates to cities and towns; urbane describes refined, courteous manners.
- urban — relating to, or located in, a city or town, as opposed to the countryside: the survey compared traffic patterns across several urban neighbourhoods.
- urbane — having refined manners; courteous, polite, suave: the host greeted every guest with an urbane smile.
How to tell them apart
Urban and urbane share the same Latin ancestor, urbs, meaning city, which is also where suburb comes from. Urban stuck close to that literal sense: it simply means "of a city." Urbane took a more figurative path, coming to describe the polished manners once associated with city dwellers rather than the city itself.
A simple way to keep them straight: urban is a place word, so it pairs naturally with nouns like area, planning, or poverty. Urbane is a people word, describing how someone behaves or presents themselves, so it pairs with nouns like charm, manner, or host. If you are describing a location, use urban; if you are describing someone's sophistication, use urbane.
