What world languages do you know?

I am okay with written, spoken Chinese... although I mix in a lot of English words because I forget how to say things in Chinese a lot of the time if I don't use the term often...I can communicate reasonably well in Japanese, written and spoken aspects, and still working on Korean, I can catch a word here and there when I listen to a conversation, and I can read an article out aloud but I might just not understand a word of it...though I found it easier to study because of the similarity of sentence structures, so take a Japanese sentence, insert the appropriate particles in Korean, and you have a perfectly grammatical Korean sentence. And ofcourse, reasonably fluent in English.

I love learning languages, but if I try to do too many at a time, I mix up... >_>
Like trying to speak to my Korean lecturer in Japanese. GAH.
