I was at one point fully fluent in Spanish, though my skill has degenerated substantially even in the few years since leaving college. I also speak a bit of Arabic (also from college), as well as whatever Latin I can recall from high school. And English, of course.
And, since Xahar mentioned it, I know the Greek alphabet (modern as well as some of the archaic letters) and therefore can read Greek but cannot understand it.
In that case, I know the Cyrillic alphabet.
Same for me with regards to Hebrew.
