Hi everyone,

You enter a cafe and ask :

çay var mı?

Does it mean:

 " do you have tea"?

Or 

Is there tea?

It means; do you have a tea ?

Yes in that context it´s like: do you have tea?

But here is the literal T/E:

Çay var mı? Is there tea?

Çayın var mı? Do you have tea?

Really I would use çayınız here. Like the other post, if you are a stranger or in a shop or restaurant and you don´t know the person helping you, it really is more polite.

It´s like saying the french ´tu´ or German ´du´ or Dutch ´jij´: it´s kinda rude if you don´t know the person.

Good point.

...

Çayın var mı? Literally, do you have tea? 

Çayınız var mı? Same but more polite, better to use this one at stores.

So guys, in the literal meaning, it means "is there tea?"

But in that context it means "do you have tea"?

Say I wanna ask someone "do you have a car?

Shall I use "var mi"?

Bir araban var mı?

Add the ´n´ for you.

With çay var mı? there is nothing grammatical to say ´you´. But this is informal, and the meaning is equivalent to ´do you have tea´.
