The pronominalizing -ki is usually used for talking about things in relation to each other. In this form, -ki is attached to a genetive case suffix. For example, benimki means mine and arabanınki means the car's.
Remember that -ki does not behave according to vowel harmony.
|My grandfather is alive, (how about) yours?||Benim dedem yaşıyor, seninki?|
If suffixes follow -ki, they are preceded by a buffer letter n.
|You're taller than me.||Sizin boyunuz benimkinden daha uzun.|
