days - day with an "s" - or not

Good news for French and Spanish. To make something plural, just add an "s":

Spanish día becomes días, pronounced "dee-ahss".

French jour becomes jours, pronounced "zhoor".
What about the "s"? Not pronounced. Say jours just like jour. You didn't think "just add an s" was that easy, did you?

In Italian, it's all mucked up. Here's the short scoop for so far: If it ends in "o" in Italian, the plural ends in "i".

Italian giorno becomes giorni, pronounced "jor-nee".
