Fluently, just English. I've studied Japanese for a bit, and I really want to learn it at some point, but I definitely can't speak conversationally. >_< I know enough to pick words or glean meanings from sentences to form a general idea of what someone is talking about, but I don't have near enough to understand it word-for-word.
I'm only fluent in English. I studied Spanish for several years, but it's been a while since I used it. I also had a brief stint with Swedish. Now I'm learning Korean (Hangul) and hoping this leads to actual bilingualism.
I can speak Polish fluently ( it is my native language) and I learn English, German and Russian. I can also write few Chinese marks 'cause I'm planning to start studying it at least. In the nearer time, I would like to learn some Italian, too.
I speak fluent Filipino since it is my native language. Also fluent in English. Then, basic Japanese (my high school included the language for all 1st year students only then after that everything's basically self-study) and a little bit Korean (I can read and write hangul but I can only understand some words).
I'm fluent in English (but I have bad grammar...) and can speak conversational Cantonese. I know some Japanese because I took Japanese class in high school.
I'm currently teaching myself Mandarin and if I ever have time I want to learn Korean.
My native language is English, but I live in Texas so I basically had Spanish crammed down my throat from the time I started school. It was really inconsistent, though, and I've forgotten most of it since graduating even though I took three years of it in high school. I'm studying French in college now and I also know a few basic signs in ASL.
