Thank you very much, but you give me a very good answer, but can anybody tell me more in another way.
in another way, that means you are right, but maybe have some simple way to make me understand more, one arab always said to me like this way" if you don't understand, tell me you don't understand, i will show you another way"

because he is not good at english, so he speak like that.
but here i just mean i want to know more about the two one, and one more thing, sometimes i even can not tell the different from turk and some people speak russian!

Thank you so mcuh SLTM

Do you mean the russian and the turkish language?

i mean the people, sometimes i also don't know what is the different if they keep silent

İts hard question tho,no one can distinguish people by appearance,but maybe there is some main feature can distinguish each region.
For example Arabs not all the same too,there is a great differences among them.

Firs,mainly,arab are the people who were living in the deserts.
So you can see,Saudi Arabians,Yemen,and the Gulf people are much close to each others,dark hair,eyes,olive skin,and hard features
Up,Syria,Lebanon are bit close to each others,a bit coloured,Fair
Jordan,Palestine are much close too,not dark,and not fair too,but mixed,and you find brown eyes,hazelnuts,not hard features
North Africa,as Algeria,Tunisia,and Morocco are a bit same,and close to people in the gulf area in places where is desert too .
Egypt,you can find all there too,coloured,not coloured,dark,mix,fair,but no hard features.

You can distinguish Turk from Gulf Arabian people very well i guess,and people who live close to desert places,but other wise,i dont think so.

I live in syria & I am originally turkish (turkmen).
