How are you?

Let's see how you can say "How are you?". There are several ways to do that. You can say:

ازيك؟
Ezzeyak (if you are talking to a man)  or ezzeyek (if you are talking to a woman).  

You can also ask:

عامل ايه؟
3amel eih?
(3 stands for ع)
If you are talking to a man or

عاملة ايه؟
3amla eih?
If you are talking to a woman. 

Another way is to say :

ايه الأخبار؟
Eih el-akhbar? 
 
That literally means "What's new?", but in fact means also "How are you? " so you just have to answer "Fine".

Now how do you say "fine"?
You can say 

تمام
Tamam
 
زي الفل
Zey el-ful
(the literal meaning is "like Arabian jasmine")

Or 

كويس
Kweyyis (if you are a man)
كويسة
Kweyyisa (if you are a woman). 

But no matter which answer you choose, to sound truly Egyptian you should add 

الحمد لله
Al7amdulillah
(7 stands for ح). 

Which means "Thank God" and which you simply can't survive without living in an Arab country.
Be prepared one question to ask how you and your family are is never enough for Egyptians even if the answer is always the same. They spend at least 2 minutes asking again and again: 3amel eih?  Ezzeyyak?  Eih el-akhbar? Tamam?  Kweyyis?  .....
Don't be confused, smile and answer al7amdulillah,  al7amdulillah,  tamam, al7amdulillah. W enta 3amel eih? Al7amdulillah.

 طب ازيك؟
Tab ezzeyyak?
So how are you?
