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.
