banlieue

Banlieue is the French word for "outskirts." A banlieue can be rich or poor; Versailles, Le Vésinet, Orsay and Neuilly-sur-Seine are affluent banlieues of Paris, and Clichy-sous-Bois is a poor one. It comes from the two French words ban (Medieval justice) and lieue (a unit equivalent to four kilometers), and thus describes the zone around a city that is under the city's rule.
