early 14c., "area outside a town or city," whether agricultural or residential but most frequently residential, from Old French suburbe "suburb of a town," from Latin suburbium "an outlying part of a city" (especially Rome), from sub "below, near" (see sub-) + urbs (genitive urbis) "city" (see urban). Glossed in Old English as underburg. Just beyond the reach of municipal jurisdiction, suburbs had a bad reputation in 17c. England, especially those of London, and suburban had a sense of "inferior, debased, licentious" (as in suburban sinner, slang for "loose woman, prostitute"). By 1817, the tinge had shifted to "of inferior manners and narrow views." Compare also French equivalent faubourg.
