To my little ear the most beautiful will always be my dialect of Norwegian. When I hear that, I know I'm HOME. How could that not be beautiful to anyone, to hear their own language after living in a new country so long? I've always thought Arabic looked very pretty. I don't understand much of it when it's spoken as I've never really studied it. I just picked up a few things during my deployment when I was in the Army. (that fast tracks your US citizenship, btw. Which is why I did it.) I can't read a word of it but, I think it is so beautiful looking, the way it just "flows".

I always say that it depends who's speaking it!

I think it the language of your mother, your loved person and your children. Even if they keep silece.

Your own native language.

Russian. The next one is French.
