I've always, always wanted to learn another language, but was discouraged from it (I won't get into the details). I don't have the discipline to teach myself but don't have the time / money to take a class, and honestly to the extent that I do there other subjects I'm even more interested in that I'd probably devote time to instead.
But, I do hope to learn at least one other at some point in my life.
English is my second language. I know two local languages in my part of the world, although one I know I few words and I can't read it. Tried to learn Spanish and french without classes. I know a little latin too.
English is the only language I speak. I know some French thanks to school (they made it a requirement course like almost every grade) and ballet classes. There are some words here and there from other languages that I know, but I wouldn't say I'm fluent. I would really like to know a bunch of languages. I find that aspect of humans amazing... the fact we can speak and communicate in so many different ways.
Mandarin, English, Japanese. Finding no time for Korean right now, otherwise I know all the characters/alphabets (?) and can catch a few words or two. Nothing close to understanding or fluency like the mentioned 3 though. Some of the Korean pronunciations and grammar structure are so close to Japanese and Mandarin that I'm still trying to find a good strategy/method to remember stuff.
The only language I consider myself fluent in is English.
I've studied French, Latin, and Hindi through classes, but with very few people to converse with my skill tends to deteriorate quickly. I'd say I'm at an elementary level speaking French, but can generally read it just fine. Latin I'm sure I've forgotten most everything by now and my Hindi only comes into play when watching films these days.
Aside from that I've had casual interests in several other languages, but it usually comes down to having no one to practice with.
I'd love to have the talent required to be a polyglot. My cousin (who probably greatly influenced me as a child in this respect) speaks 7 or 8 languages fluently (did so by the age of 16) and is now a permanent resident of France working as a translator. He just has a head for it, I guess.
I love foreign languages, but I can' t really say the scientific/ linguistic approach is something I enjoy. I would rather learn other languages by myself, if possible, or by spending time with native speakers.
English is not my native language, so I can count two, so far. I am currently learning the third one, too.
I also know a fourth language, at an A2 level, maybe, or between A2-B1. I'm still working on it.
