you learn an expression and you will see that every area has a very different dialect

for example how they say I want

ana Oridu - classic way
Aiza - egyptians
biddi -palestinians
and my Arabic is poor I am sure that there are a lots of other expressions ...

Virtually - it seems to me at times that there is no such thing that Arabic - and you can not say - ok I just want to learn one kind of arabic because you will meet every kind of people here from the Arab world ...
