The sounds are hard. Pronunciation is difficult as well, I tend to pronounce the words with a Spanish sound. I think with any language, it is difficult to train your brain to move muscles in your mouth that you may not be used to using, you know what I mean?
There is a rhythm to the language and I have NO rhythm! I sound crazy, so I got a lot of work to do.
Vocab has got som kind of structures to coclude a word from the base verb its quite easy :)
Sounds of arabic arnt that hard its just the glottal ones :D the rest is easy ou can call them "hard" sounds of the latin sounds
you can always find a good song that makes you feel good and keep repeating the words "meanings ain important" and you will be through pronounciation ::)
