la déception: disappointment (n.)

Le dîner était horrible. Quelle déception! The dinner was horrible. What a disappointment! Pronounced: "day-sep-see-own" Grammar note: If you want to say the English term deception then you should use tromperie or the verb tromper. Pixies fans should recognize trompe from an album of theirs titled Trompe le Monde which literally means deceive the world or deceive everyone. A common expression in French is "Oh, je suis désolé, j'ai trompé le numéro." That's how you say "Oh, I'm sorry, I misdialed the phone number."
