"suburb," late 15c. (early 15c. fabour), from Old French forsbourc, faubourg (12c.) "suburbs, outskirts," literally "that which is outside the town," from fors "outside" (from Latin foris; see foreign) + bourc "town" (a word of Frankish origin cognate with English borough). Altered in French by folk-etymology to faux bourg "false town" (suburbs were seen as inauthentic).
