Turkish Possessive Suffixes: -im, -in, -i Explained
How the Turkish possessive suffixes attach an owner to a noun — the four-way vowel harmony that shapes the linking vowel, why that vowel drops after a vowel while the third person gains an -s-, and why evi means both "his house" and "the house".

Turkish marks possession with a suffix on the noun that is owned — a different ending for each person, chosen and shaped by vowel harmony.
What the possessive suffixes do
Turkish attaches the possessive ending to the thing that is owned, not to the owner. evim is "my house" and evimiz is "our house" — the noun ev stays put and the ending does the work, naming at once what is owned and who owns it. There is one such ending for each of the six persons.
The linking vowel harmonises four ways
After a consonant, each ending opens with a high linking vowel, and that vowel copies both the frontness and the rounding of the noun's last vowel. The first-person ending shows all four shapes: -ım on a back unrounded stem, so kızım; -im on a front unrounded one, so evim; -um on a back rounded one, so okulum; and -üm on a front rounded one, so gözüm.
| Last vowel | First-person ending | Example |
|---|---|---|
| a · ı | -ım | kızım |
| e · i | -im | evim |
| o · u | -um | okulum |
| ö · ü | -üm | gözüm |
The grid shows this on the first-person ending, and the same four-way choice runs through the linking vowel of every other person. Read the last vowel of the noun and the ending falls into place.
When the noun ends in a vowel
When the noun already ends in a vowel, the linking vowel has no work to do and falls away: araba takes a bare -m to give arabam, "my car". Keeping the linking vowel here, arabaım, is not Turkish.
The third-person ending behaves the other way round. Its vowel belongs to the suffix, so it stays; to keep it from colliding with the stem's final vowel, an -sı steps in with a buffer consonant, and araba becomes arabası, "his car". Writing arabaı with the two vowels touching is not possible in Turkish.
| Turkish | Parts | English |
|---|---|---|
| arabam | araba + m | my car |
| arabası | araba + sı | his, her, or its car |
The six persons side by side
| Turkish | Parts | English |
|---|---|---|
| evim | ev + im | my house |
| evin | ev + in | your house (one owner) |
| evi | ev + i | his, her, or its house |
| evimiz | ev + imiz | our house |
| eviniz | ev + iniz | your house (several owners, or polite) |
| evleri | ev + ler + i | their house(s) |
One noun, ev, carries six different owners with nothing changing but the ending. The last of them, evleri, is read from context: it covers "their house", "their houses", and "his houses" alike.
Telling the possessive from the accusative
The third-person possessive shares its shape with the accusative, the ending that marks a definite object. After a vowel the two stay apart, because each takes its own buffer: arabası carries an -s- buffer and means "his car", while arabayı carries a -y- buffer and means "the car" as a definite object. After a consonant there is no buffer to keep them separate, so evi reads as either "his house" or "the house" — only the surrounding sentence decides.
This is a boundary note; the accusative is a topic of its own. The point to carry away is that evi standing alone is ambiguous, while arabası and arabayı each say exactly one thing.
| Turkish | Parts | English |
|---|---|---|
| evi | ev + i | his house — or the house as an object |
| arabası | araba + sı | his car |
The possessor pronoun is optional
The ending already names the owner, so Turkish usually leaves the possessor pronoun out: evim on its own is "my house". Adding benim, "my", in front is possible, but it puts weight on the owner — "my house, not yours" — where the ending alone would already be understood.
Frequently asked questions
- Which possessive suffix goes with which person?
- Each person has its own ending on the noun: evim "my house", evin "your house", evi "his, her, or its house", evimiz "our house", eviniz "your house" for more than one person or for politeness, and evleri "their house". After a consonant the linking vowel harmonises four ways; after a vowel it drops.
- Why is it arabası and not arabaı?
- Because araba ends in a vowel, and the third-person ending brings its own vowel with it. Turkish does not let two vowels meet at the seam, so a buffer -s- slides in between them, giving arabası. The form arabaı, with the vowels touching, is not Turkish.
- Does evi mean 'his house' or 'the house'?
- It can be either. After a consonant the third-person possessive and the accusative fall together, so evi is "his house" as a possessive and "the house" as a definite object at once, and the sentence around it decides. They separate after a vowel, where arabası is "his car" and arabayı is "the car".
- Do I need benim to say 'my house'?
- No. The ending already carries the person, so evim on its own is fully "my house". benim "my" is added only to stress who the owner is, not to be understood — the suffix does that work by itself.
