I study Classics, so I speak both Latin, which I've been learning since I was ten, and Ancient Greek. I'm also starting Ancient Akkadian this summer at the British Museum, which I am tremendously excited about.
I also speak Spanish, which is very easy for me as it's just simplified Latin with all the scary bits taken out. And I can get the gist of modern Greek if it's written down, because it seems it hasn't changed that much. Strictly, however, that doesn't count.
I just which I could speak Italian! Now that is a beatiful language. The language of Dante.
