A Francophile is a person who loves France, French things, and French people. If you start wearing a beret and carrying a baguette around with you, your friends will assume you're a Francophile.
Francophiles have a special appreciation for all things French: they might admire the language, envy the country's inhabitants, or prefer to buy food that's made in France. If you're a Francophile who's never traveled to France, you can save your money for this purpose, in the meantime learning to speak French and dining on Brie and Champagne whenever you can. Francophile combines Franco-, "French," and -phile, "one that loves."
