Did you know?

"Flea market" gets its name from the French "Marché aux Puces" (literally flea market), the famous outdoor market on the edge of Paris. Second-hand clothing and old furniture were said to potentially harbor fleas. Founded in the late 19th century on the outskirts of Paris, it is now one of the world's largest antique markets with over 2,000 dealers. "Flee" comes from Old English "fleon" (to run away), the same root as "fly" in its older sense of rapid movement.
