Great question — I wondered the same thing at one point too!
The term “flea market” actually comes from the French phrase “marché aux puces”, which translates to “market of the fleas.” It started in Paris in the 19th century, where people would sell second-hand clothes, furniture, and other goods, many of which were so old and used that they supposedly had fleas 🪳😅.
Over time, the name stuck, even though modern flea markets are just fun places to hunt for vintage finds, handmade crafts, collectibles, and more. No fleas required!
Kind of crazy how something so casual today has such a quirky origin, right?
