lots of dialects ,,,just in my country there are more than 3 ... every region has its own deferents " southern , middler , eastern " , the difference maybe in pronouncing the words " which is the most " or the meaning of the words ,,, they still similar though ,,,, all the gulf countries are similar even though the accent maybe different ,,,
but if you want to notice the real different listen to Syrian or Egyptian ...
but hey ,,, these are not the original Arabic . Original Arabic is just one ,,, and this what I meant when I said it's harder than English ,,,
I know somebody who has learned Persian/Farsi and he says it is similar to Arabic writing but most of the words are different.
Yes , he is right ,,, its so similar in letters and some of the words ,,, I don't know it so I can't judge ,,, but there is a lot of deference ,,,, I will ask for you if you want ,,,
