In English, possession lives in a separate little word in front of the noun: my house, your car, her book. Turkish does it the opposite way — it glues a possessive suffix onto the thing owned and lets that suffix carry the whole meaning. "My house" is literally "house-my," evim, a single word. There is no separate word for my at all. This page teaches the six possessive suffixes, one for each grammatical person, and the small spelling adjustments (vowel harmony, a buffer s) that make them fit any noun.
The core idea: mark the owned thing, not the owner
This is the mental flip an English speaker has to make. Look at the noun ev "house" and watch the ending change to show who owns it:
| Person | Suffix | ev "house" | Meaning |
|---|---|---|---|
| 1st sg | -(I)m | evim | my house |
| 2nd sg | -(I)n | evin | your house |
| 3rd sg | -(s)I | evi | his/her/its house |
| 1st pl | -(I)mIz | evimiz | our house |
| 2nd pl/formal | -(I)nIz | eviniz | your house (pl/polite) |
| 3rd pl | -lArI | evleri | their house(s) |
Notice there is no word my, your, her anywhere — the person is baked into the ending. evim all by itself means "my house." That single word is a complete possessive noun phrase.
Evim çok küçük ama bana yetiyor.
My house is very small but it's enough for me.
Adın ne?
What's your name?
Annesi onu her gün okula bırakıyor.
His mother drops him at school every day.
The four-way harmony: the capital I is a chameleon
The capital I you keep seeing in the suffix names (-(I)m, -(I)n, -(I)nIz) is shorthand for a high vowel that changes shape to match the last vowel of the noun. This is four-way vowel harmony: the vowel surfaces as i, ı, u, or ü depending on whether the stem's last vowel is front/back and rounded/unrounded.
| Last stem vowel | Harmony vowel | "my" example |
|---|---|---|
| e, i | i | ev → evim, diş → dişim |
| a, ı | ı | kız → kızım, ad → adım |
| o, u | u | okul → okulum, kol → kolum |
| ö, ü | ü | göz → gözüm, gün → günüm |
So "my eye" is gözüm, "my arm" is kolum, "my daughter" is kızım — the suffix vowel always echoes the noun.
Gözüm çok yoruldu, biraz mola vereyim.
My eyes are really tired, let me take a short break.
Okulumuz şehrin merkezinde.
Our school is in the city centre.
The buffer s in the 3rd person: arabası, kapısı
The 1st- and 2nd-person endings just need a vowel when the noun already ends in a vowel — araba "car" → arabam "my car," araban "your car." But the 3rd-person singular -(s)I has a special trick. After a noun that ends in a vowel, you can't simply add -i, because two vowels can't sit side by side. Turkish slides a buffer consonant s between them:
- consonant-ending: ev → evi "his house" (just the harmony vowel)
- vowel-ending: araba → araba-s-ı = arabası "his car" (buffer s
- harmony vowel)
- vowel-ending: kapı → kapı-s-ı = kapısı "its door"
- vowel-ending: anne → anne-s-i = annesi "his/her mother"
This s is the single most recognisable signal of the 3rd-person possessive. Whenever you see an -sı, -si, -su, -sü glued onto a noun ending in a vowel, you are almost certainly looking at "his/her/its X."
Arabası bozulunca işe otobüsle gitti.
When his car broke down he went to work by bus.
Çantanın fermuarı yine sıkıştı.
The bag's zip got stuck again.
Bu kapının anahtarı kayıp.
The key to this door is lost.
A consonant can soften: kitap → kitabım
Some nouns ending in a hard consonant p, ç, t, k soften it to b, c, d, ğ when a vowel suffix is added. This is normal Turkish consonant softening, and it happens with possessives just like any other vowel-initial ending:
- kitap "book" → kitabım "my book," kitabın "your book"
- ağaç "tree" → ağacı "its tree"
- renk "colour" → rengi "its colour"
Kitabın çantamda, akşam getiririm.
Your book is in my bag, I'll bring it this evening.
The optional pronoun: benim only adds emphasis
So if the suffix says everything, what is benim ("my," literally the genitive of ben "I") for? It is optional emphasis. You add the standalone possessor word only when you want to stress whose it is — to contrast, correct, or point out ownership. See personal genitive pronouns for the full set.
- Evim — "my house" (neutral, the default)
- Benim evim — "my house" (mine, as opposed to yours)
Crucially, even when you add benim, the suffix stays on. The owner word and the suffix work as a pair, exactly like the genitive izafet. You never drop the suffix just because you've written the pronoun.
Bu senin kahven mi, benim kahvem mi?
Is this your coffee or my coffee?
Onun fikri benimkinden çok daha iyi.
His idea is much better than mine.
Common mistakes
❌ Ben ev küçük.
Incorrect — there's no separate word for 'my'; the suffix carries it: Evim küçük.
✅ Evim küçük.
My house is small.
❌ Benim ev şehir merkezinde.
Incorrect — even with benim, the noun still needs the suffix: benim evim.
✅ Benim evim şehir merkezinde.
My house is in the city centre.
❌ Arabam bozuldu, ona binemedik.
Wrong for 'his car' — arabam is 'my car'; 'his car' is arabası with the buffer s.
✅ Arabası bozuldu, ona binemedik.
His car broke down, we couldn't get in it.
❌ Annei beni aradı.
Incorrect — anne ends in a vowel, so the 3rd-person form needs the buffer s: annesi.
✅ Annesi beni aradı.
His mother called me.
The number-one English-speaker error is importing the English structure: putting a possessor word in front and leaving the noun bare (ben ev for "my house"). Turkish demands the suffix. The second classic slip is forgetting the buffer s on a vowel-final noun in the 3rd person — writing kapıı or arabaı instead of kapısı, arabası.
Key takeaways
- Turkish marks possession on the owned noun, not with a separate word: evim = "my house," a complete phrase by itself.
- The six suffixes are -(I)m, -(I)n, -(s)I, -(I)mIz, -(I)nIz, -lArI, giving evim, evin, evi, evimiz, eviniz, evleri.
- The vowel obeys four-way harmony (i/ı/u/ü): gözüm, kolum, kızım.
- The 3rd-person -(s)I adds a buffer s after a vowel: arabası, kapısı, annesi — but the 1st/2nd persons do not (arabam, araban).
- The standalone possessor word (benim) is optional emphasis only; the suffix must stay either way. See genitive and definite izafet for two-marker possessive phrases.
