Sure its difficult language for Russian speaking people too, but mentally we are closer to Arabic people, that's make learning this language easier I think.  

arabic is easy if u use each word u learn .. like any language

Hellow.Although Arabic language is hard,but it is wonderful .It is the language of the Holly Quran that had given to all people in the world. 

Arabic is a hard language for English speakers because you have to learn a completely different alphabet, syntax, and pronunciation.  Some sounds of which you have never made with English.

its difficult to pronounce some words if you are not used to using your mouth correctly
