Maybe I should get started if I really want to teach myself Arabic...
The only language I can actually use other than English is Spanish but I'm no expert. I only took up to Spanish 3, I wasn't really interested in all of the speaking projects in Spanish 4 and AP. I can recognize a lot of languages, though. Kind of falls apart in Eastern Europe with Swedish, Finnish, and Czech; I don't have much experience with those.
Man I love language. If I were better at it (and it were a bit more exciting, honestly), I'd probably be an etymologist.
