About language study.
As I know, many western people, especially from Europe, can speak many languages. For example, Swedish people can speak Swedish, Norwegian, Finnish, Danish and English. Swiss people can speak German, French and Italian.
So I just wanna know if I learn 8 languages, is it enough for me to visit Europe or other areas? I'm gonna learn English, French, German, Italian, Portugese, Spanish, Dutch and Japanese. Now I have mastered English and learning Japanese and German.
Thank you.

Question

Answer

The two most common languages in Europe are English, then German. You can survive with these two languages, but to visit many countries in Europe you may want to learn more. I suggest this order of priority:

1 English, 2 German, 3 French, 4 Spanish, 5 Italian...

However, Holland, Sweden and certain other countries speak English very well, with many people speaking English almost like a native speaker. This is my personal experience.
