I agree! Learning any language that is not your native tongue can be very difficult. But if you really want to learn it you can. Many people are afraid of Russian and Greek because the alphabet is different. But once you learn Cyrillic letters the words are easy to pronounce. The grammar can be difficult, but that is true of every language.

Do you think Bahasa is easier for russian people? Our writing much easier than english, because we mostly write words exactly as they sounds

If you had ever learned Arabic, you would not ask "Why is Russian language so difficult to learn?".

Well, I don't agree that it's too difficult. Who told you that? :-) Of course Russian grammar isn’t easy but nothing is impossible in life! If Russian had been too difficult, nobody would have been able to learn it. If you really want to learn it just do it!

My native language - Russian. I am studying Arabic. Do you think me easy to learn Arabic? ЛИХА БЕДА НАЧАЛО (LIHA BEDA NACHALO) = ALWAYS BEGINING IS DIFFICULT (eng)
