Hello Nina, to really learn a language it is absolutely necessary to talk. Making mistakes is the best way to learn. I think a lot of people (and definitely oriental people) are reluctant to speak because they have the feeling that they will 'lose face' if they make a mistake. This is not true. Most people will appreciate the effort of someone to learn their language and will be happy to help. My answer to your question therefore is: the most important is to communicate without fear of making mistakes. Take care, dirk

I think both are important, but for first the pronounciation then grammer, but for learning i think grammer first.
