Learn Turkish: Zamanın var mı?

Turkish doesn't have a direct verb for "to have." Instead, you use a structure that literally translates to "your [thing] exists." Here, zamanın means "your time" and var means "there is" or "exists." Asking "Does your time exist?" is how you ask "Do you have time?" in Turkish.

What does the -ın at the end of zamanın do?

It is the possessive suffix for "your" (informal/singular). The root word is zaman (time). By adding -ın, it becomes zamanın (your time).

Could I say Senin zamanın var mı? instead?

Yes, you can! Senin means "your," but because the -ın on zamanın already tells us exactly whose time it is, the word senin is usually dropped in everyday conversation unless you want to put special emphasis on "your" time.

Why is the question word mı and not mi or mu?

The question particle always changes to match the vowel harmony of the word right before it. The word before it is var, and its vowel is 'a'. In Turkish, if the last vowel is 'a' or 'ı', the question word must be mı.
