Is the suffix for sen ´-sin´? I thought it was ´-in´ ?

 I am just going to do this very basically , but there are lessons on this site that would help you.

I think you are confusing the possesive noun suffix wih personal pronouns

For example ´in ın ün un ´ (in  its forms in relation to vowel harmony) would add the meaning  ´your´

Senin bluzun = Your blouse (senin is not needed but adds emphasis)

senin yoğurtun = your yogurt

If the noun ends in a vowel instead of adding un in ın or ün you just add N

for example - senin araban = your car

examples of sin ( or its other vowel harmony forms)

Hastasın - You are ill

Delisin = You are crazy

Guzelsin = you are beautiful

körsün= you are blind

Just a small remark: yoğurtun has to be yoğurdun.

 oppps of course ..  Thanks

Thank you so much for the reply....i think i am getting a bit confused with all the suffixes!

You can also find the form :´yoğurtun´

 ohhh now I´m confused

The lesson  I referenced and my own class says

" If one of "p, t, k and ç" remains between two vowels (such as "kitap") they become "b, d, ğ and ç"

I thought I had simply forgotten and when melike pointed it out i saw my mistake instantly

How come this can be in this form ? Could you explain so I can understand . Many thanks

Well I saw yoğurtun and I just knew it was wrong.

So for being sure I asked my husband and he said it had to be yoğurdun indeed.

I don´t know very much about grammarrules unfortunately because most Turkish I learned by listening and talking with my husband and family in law, but I found this topic for you, maybe it can help: http://www.turkishclass.com/forumTitle_28382

 Thank you  That reconfirmed how I understood it

But turkish also use ´Yoğurtun faydaları´ for example...
