Мне стало больно от ответа первого человека, так что вставлю свои пять копеек.
1) In my opinion one of the hardest languages is Hungarian. Although it is a European language, it has nothing in common with the languages of Europe. What is more, it has a unique structure that is pretty hard to understand.
2) As for me, English is really important, because it is the main international language nowadays. It allows us to communicate with each other no matter in what countries we live. Also I find Spanish interesting, because it is the second world's largest language and is considered one of the most beautiful and easy languages to learn and speak.
