The Turkish -ki Suffix: -deki, -daki
-ki Eki (-deki, -daki)
Turning a place, a time or an owner into a describing word: masadaki, bugünkü, benimki
-ki turns a place or a time into a describing word: the one that is there, the one of that time. masadaki kitap (the book on the table), yarınki maç (tomorrow’s match). On an owner word it names the thing that belongs to them: benimki (mine).
After a place it follows the locative: ev → evde → evdeki (the one at home). The harmony and the d/t change happen in -de: okuldaki, sokaktaki, sepetteki. -ki itself stays -ki.
Two exceptions take -kü: dün and gün (dünkü, bugünkü). A -ki word can go before a noun (masadaki kitap) or stand alone as the one: Masadaki benim (the one on the table is mine).
Examples
Masadaki çay soğuk.
The tea on the table is cold.
Bugünkü ders çok kolay.
