The genitive case marks a noun or pronoun as the possessor of, or in a close relationship with, another noun. The marker is -(n)In, which attaches to the possessor and typically works together with a possessive suffix on the noun that follows.
1. Function / Meaning
The genitive suffix most often marks ownership, but it also expresses part-whole relations, association, or a defining connection between two nouns.
Examples:
Ali'nin arabası (Ali's car — ownership)
Türkiye'nin başkenti (Turkey's capital — part-whole)
filmin sonu (the end of the film — relation, not ownership)
2. Form and Structure
Noun stem → -(n)In, with four-way vowel harmony:
a, ı → -ın
e, i → -in
o, u → -un
ö, ü → -ün
Examples:
Ahmet-in
öğretmen-in
okul-un
öğrenci-nin
3. Buffer Consonant -n- in the Genitive Suffix
When the noun ends in a vowel, a buffer -n- appears before the suffix.
Examples:
oda → oda-nın
araba → araba-nın
anne → anne-nin
kedi → kedi-nin
Exception: su → suyun. The word su uses the buffer consonant -y- instead of -n-.
4. Personal Pronoun Genitive Forms
Personal pronouns take special genitive forms rather than the regular -(n)In pattern. These are best learned as a set:
ben → benim (my/mine)
sen → senin (your/yours)
o → onun (his/her/hers/its)
biz → bizim (our/ours)
siz → sizin (your/yours)
onlar → onların (their/theirs)
Examples:
benim kitabım (my book)
onun arabası (his/her car)
bizim evimiz (our house)
5. Asking About Possession or Relation
Kimin is the genitive form of kim (“who”), while neyin is the genitive form of ne (“what”).
Kimin? — Whose?
Neyin? — Of what?
Examples:
Kimin çantası bu? — Whose bag is this?
Bu kalem kimin? — Whose pen is this?
Neyin kokusu bu? — What is this the smell of?
6. Genitive Forms Without a Following Possessive Noun
The genitive does not always require a possessive-marked noun right after it. It can stand alone as a predicate, or appear before certain postpositions with personal pronouns.
Examples:
Bu kitap benim. — This book is mine.
Bu kalem senin mi? — Is this pen yours?
Benim için bir hediye aldı. — He/she got a gift for me.
Senin gibi çalışıyor. — He/she works like you.
Onun kadar hızlı koşamam. — I can't run as fast as him/her.
7. The Genitive-Possessive Construction
A full possessive phrase pairs a genitive-marked possessor with a possessive-marked possessed noun, agreeing in person.
Structure: (possessor + genitive) + (possessed noun + possessive)
Examples:
Ali'nin oğlu (Ali's son)
odanın kapısı (the door of the room)
annemin evi (my mother's house)
Note: anne-m-in, the 1st person possessive -m and the genitive -in stack on "anne")
The possessor pronoun can be dropped when the possessive suffix already makes the meaning clear:
benim kitabım → kitabım
bizim evimiz → evimiz
8. Case Suffixes on the Whole Phrase
When the phrase needs a further case ending, it attaches to the possessed noun at the end. A buffer -n- appears only if that noun carries a 3rd person possessive suffix; 1st and 2nd person possessive forms take the case ending directly, with no extra -n-.
Examples:
Ali'nin evinde (in Ali's house) — 3rd person possessive, -n- appears
benim evimde (in my house) — 1st person possessive, no extra -n-
senin evinden (from your house) — 2nd person possessive, no extra -n-
Examples
Ahmet'in arabası. — Ahmet's car.
Öğretmenin kitabı. — The teacher's book.
Okulun bahçesi. — The school's garden.
Bu kalem kimin? — Whose pen is this?
Bu kitap benim. — This book is mine.
Benim için bir hediye aldı. — He/she got a gift for me.
Ali'nin evinde kalıyorum. — I'm staying at Ali's house.
Benim evimde kalıyorsun. — You're staying at my house.
Notes
Genitive marks ownership most often, but also part-whole relations and other close associations, not only literal possession.
Genitive-marked words don't always need a following possessive noun. They can stand alone as predicates or appear before postpositions like için, gibi, kadar with personal pronouns.
Personal pronoun genitive forms don't follow the regular -(n)In pattern and should be taught as a set.
The buffer -n- before a case suffix appears only after a 3rd person possessive ending, not after 1st or 2nd person possessive forms.
A possessor can be dropped once the possessive suffix already shows who it belongs to (benim kitabım → kitabım).
okulun bahçesi (a specific school's garden) differs from okul bahçesi (school garden, a type). The first noun takes no suffix in the second pattern. This distinction is covered fully in the next lesson, Noun Phrases: Definite and Indefinite.
