Did you know?

A 'flea market' gets its name from the French 'Marché aux Puces' (literally flea market), the famous outdoor market at the edge of Paris. Second-hand clothing and old furniture were said to potentially harbour fleas — hence the name. The Paris Marché aux Puces, established in the late 19th century, is now one of the world's largest antique markets. 'Flee' comes from Old English 'fleon' (to run away) — the same root as 'fly' in its older sense of rapid movement.
