herkese selam!

Sometimes we use the fusion consonant "Y", example: odaya (to the room). I know another consonants fusions are "s" and "n" but can someone help me to know when I should use them?
are there are web site which clarify these sitations?


Thank you very much

the buffer letter "y" is usually added on to a word that:
- ends in a vowel and the suffix added to the word starts with a vowel
- doesn't already have a suffix added to it

ex. kedi
kedi + y + e
kediye = to the cat

the buffer letter "s" is usually added on to a word that:
- ends in a vowel and the suffix added to the word starts with a vowel
- used to mark the 3rd person singular posessive suffix
- doesn't already have a suffix added to it

ex. kedi
kedi + si
kedisi = his cat

the buffer letter "n" is usually added to a word that:
- already has a suffix added to it
- the first suffix ends in a vowel and the second suffix added to the word starts with a vowel

ex. kedi
kedi + si
kedisi = his cat
kedi + si + n + e
kedisine = to his cat
