Turkish has six cases. That sentence frightens people who have met the word "case" in a Russian or German classroom, where it usually arrives as a wall of tables to be memorised before anything useful can be said.
Turkish cases are not like that, for two reasons. They are completely regular — one ending per case, its vowel adjusting by vowel harmony and nothing else. And there is no gender, so there is only one set to learn rather than three interleaved ones. Six endings, total.
Better still, four of the six are doing jobs English handles with prepositions. If you can use "to", "in" and "from", you already understand most of this page.
All six, on one word
Here is ev (house) in every case. This is the whole system.
| Case | Ending | Form | Means |
| plain (nominative) | — | ev | house — the dictionary form, and the subject |
| definite object (accusative) | -i | evi | the house, as the thing acted on |
| to (dative) | -e | eve | to the house |
| in (locative) | -de | evde | in / at the house |
| from (ablative) | -den | evden | from the house |
| of (genitive) | -in | evin | of the house, the house's |
That is it. Now the same six on two other words, to show that the only thing changing is the vowel:
| Case | okul — school | göz — eye |
| plain | okul | göz |
| definite object | okulu | gözü |
| to | okula | göze |
| in | okulda | gözde |
| from | okuldan | gözden |
| of | okulun | gözün |
Same six endings, three times, with the vowels harmonising. There is no second declension, no irregular noun class, no gender to cross-reference. This is the entire noun system.
The three directions, which come as a set
Learn these three together, because they are one idea in three positions: movement towards, position at, movement away.
| Ending | Question it answers | Example |
| -e / -a | where to? | Eve gidiyorum. — I'm going home. |
| -de / -da | where? | Evdeyim. — I'm at home. |
| -den / -dan | where from? | Evden geliyorum. — I'm coming from home. |
To, at, from. English needs three separate words; Turkish uses three endings on the noun itself. If you learn nothing else on this page, learn these three — they cover an enormous amount of ordinary speech, and they are the reason İstanbul'a, İstanbul'da and İstanbul'dan all look slightly different on a sign.
Small note: after a voiceless consonant, the d in the last two hardens to t. So it is okulda but kitapta, evden but kitaptan. Same ending, adjusted to be sayable.
The accusative is really a "the" in disguise
This is the case that confuses English speakers, and the confusion disappears once you see what it is actually doing. Turkish has no word for "the" — so it marks a specific, known object with an ending instead.
| Turkish | English |
| Kitap okuyorum. | I'm reading a book. / I read books. |
| Kitabı okuyorum. | I'm reading the book. |
| Çay içiyorum. | I'm drinking tea. |
| Çayı içiyorum. | I'm drinking the tea. |
So the accusative ending is not "the object of the verb" in the way a Latin textbook would put it. It is "the object of the verb, and we both know which one". An unmarked object is general or indefinite. Once you hear it that way, choosing correctly becomes intuitive rather than grammatical.
Names and pronouns are always specific, so they always take it: Ali'yi gördüm — I saw Ali.
The genitive comes with a partner
Possession in Turkish is marked twice — once on the owner and once on the thing owned. This feels redundant and is actually rather elegant.
| Turkish | Literally | English |
| Ali'nin evi | Ali-of house-his | Ali's house |
| benim kitabım | I-of book-my | my book |
| evin kapısı | house-of door-its | the door of the house |
Because the second word already says whose it is, the first is often dropped: kitabım on its own is "my book". You will hear the full form for emphasis and the short form the rest of the time.
The buffer letters
Turkish dislikes two vowels colliding. When a case ending starting with a vowel meets a word ending in a vowel, a consonant slides in between.
| Word | Case | Result | Buffer |
| araba — car | definite object | arabayı | y |
| araba | to | arabaya | y |
| araba | of | arabanın | n |
The "in" and "from" endings begin with a consonant, so they never need one: arabada, arabadan. Two buffer letters, one rule, no exceptions — and once you know it, forms that looked irregular turn out not to be.
Six endings, one set, vowels harmonising. To, at and from are a trio worth learning together. The accusative is Turkish's way of saying "the". Everything else is buffer letters.
Try it
Put okul (school) into the right form.
- I'm going to school.
- I'm at school.
- I'm coming from school.
- I saw the school.
- the school's door (kapı = door)
Answers: (1) Okula gidiyorum. (2) Okuldayım. (3) Okuldan geliyorum. (4) Okulu gördüm — the accusative, because it is a specific school. (5) okulun kapısı — genitive on the owner, possessive on the thing owned, both marked.
How to learn them without tables
Do not drill the six down a column. Take one noun you use constantly — your city, your home, your work — and run it through the three directions in real sentences about your actual day. İşe gidiyorum, işteyim, işten geliyorum. Three sentences you will genuinely say, containing three cases, learned as speech rather than as grammar.
Add the accusative when you notice yourself wanting to say "the". Leave the genitive until you want to talk about someone else's things. The order in which you need them is the order in which to learn them.
Where this fits
Cases are the most useful endings in the language, so they sit right after vowel harmony and suffix order. Combine them with the present tense and you have most of what a beginner needs to make sentences. The roadmap has the full sequence.
