I wish I could speak Finnish. But, actually, there are tons of languages I wish I could speak. All of them, really, but Finnish is the first one I thought of just now.
I’m in the US and English is my my primary language. I studied Russian but have forgotten a lot of it. I know a few words of German and French, but very few.
Edited to add: Please tell me what your primary language is. It would also be interesting to know what other languages you speak, if any, and where you currently live.
Does music count? I don’t have much trouble with languages, but music theory has always been Greek to me.
Arabic would be interesting. Or Italian. Finnish is pretty. It has a nice rhythm.
I’m in the US and speak German and Spanish. I can understand a little Romanian.
