Because I am from Romania and I like to think I know my language well, I can say that Romanian language is a difficult one , in grammar specially that includes a lot of conjugations and grammar rules as well. I can't say Russian is more difficult than Romanian because I learned it in the elementary school and I remember that I liked it and it wasn't hard for me to understand it. I think Japaneses could be the most difficult since I don't know a single word.

I think russian is very difficult language to learn. Japanese is easy. Romanian is difficult too.

russian! russian!
