English, Spanish (not fluent, but light conversational), German (just a tiny bit less than Spanish), and a very small smattering each of Icelandic, Japanese, Koine Greek, Russian, and Mandarin. Not even enough to get by, basically enough to introduce myself and a tiny bit else. Also, I can read but not speak a very basic level of French and Italian via the Spanish. It's really amazing how close the Romance languages are to one another.
Edit: an interesting thing about Klingon. A few parents taught their kids from birth to be bilingual Klingon (one parent spoke English, the other Klingon. It's an odd feature of the human mind, but we can easily learn two, three, or more languages as infants without confusion or mixing. It gets harder as we get older). By the time the kids were 4 or 5, they had completely rejected Klingon as a language, even not knowing its origins were fake. Linguists and psychologists believe this shows the brain can distinguish between natural and artificial languages and prefers the former.
