I did not know that yesterday!

After several unprofitable starts, a search on "flea market term" turned up the goods, sort of. It proved to be one of those tricky etymology questions that's almost impossible to answer with certainty. Nevertheless, I did uncover three plausible suggestions for the origin of "flea market."

The first theory, and the one most popular on the Internet, proposes that the term is a direct translation of the French Marché aux Puces, a large, outdoor bazaar in Paris. This original market earned its name from the critter-infested goods it was rumored to sell.

The second theory alleges that the term was coined at a time when the slums and alleys of Paris were demolished and replaced by new construction. The dealers in second-hand goods who lived and worked in these old neighborhoods were forced to flee. The merchants' new gathering place was referred to as the "flee market," which later became "flea market."

The final theory associates the term with New York City's 18th century Fly Market. Apparently, the Dutch name for the market was vlie, which means valley but is pronounced "flea."

So there you have it, three flea markets for the price of one. My money's on the first explanation, but don't hold us to it.
