My mother tongue is German. Of course I can speak English.
I can read and understand French, but pretty much forgot how to speak. Spanish should be no problem if I ever find time to brush up on it. In school we also had many years of Latin, and I can still read and translate a lot.
And now I'm studying Mandarin of course, and getting better day by day. I can understand and read more than I can speak though. Very Weird.
I tried to learn Icelandic some years ago, but failed miserably.
