Can you remember the first French word you had learnt? I can. Let me take a guess about you, was it "Bonjour", "Monsieur", "Mademoiselle", "Au Revoir"? If you say yes, I can safely assume that you were the novel-reading types and you must have read these in a dozen fiction novels where the protagonist travels all over Europe trying to escape from KGB, MI6, CIA or trying to uncover some deadly conspiracy against all odds. I am equally sure that you would have pronounced them in your mind like how you would pronounce an English word. Only later, you would have known that "Mademoiselle" sounds like "memmozee" or "au revoir" sounds like "avva".
P.S: My most favorite word though is "Oui". I love the way the women say that in French movies!
