I studied Sumerian and Akkadian in grad school, and dabbled in Egyptian for a short time, and Ancient Greek as an undergrad. I know Latin well enough to tutor high school kids in it (so, basically, Cambridge Latin Course Latin... I'm not like an expert in medieval Latin or anything). Sadly, I'm pretty bad at modern languages... would be really cool if I could speak Spanish or something. :/
I once read a rumor that Sumerian and Akkadian are pretty different.
Haha, that they are!
