To say I am a doctor, Turkish does not give you a verb to conjugate — it gives you an ending to attach. Doktor "doctor" plus -um "I am" is doktorum, one word, a complete sentence. These present-tense copular person endings are the most useful thing you can learn at A1: with them you can describe yourself, others, and the world, all without a single verb. The headline fact is that the third-person singular has no ending — Bu ev güzel "This house is nice" — so "is" is literally silence.
The full paradigm
Lead with the table; everything else explains it. The capital letters mark four-way vowel harmony (the I becomes one of ı / i / u / ü), and (y) is a buffer consonant that appears only after a vowel-final predicate.
| Person | Ending | doktor (consonant-final) | araba "car" (vowel-final) |
|---|---|---|---|
| ben (I) | -(y)Im | doktorum | arabayım |
| sen (you, sg.) | -sIn | doktorsun | arabasın |
| o (he/she/it) | -Ø (nothing) | doktor | araba |
| biz (we) | -(y)Iz | doktoruz | arabayız |
| siz (you, pl./formal) | -sInIz | doktorsunuz | arabasınız |
| onlar (they) | -lAr (optional) | doktorlar | arabalar |
Read it across: with the consonant-final doktor, you just add the ending (doktorum, doktorsun, doktor, doktoruz, doktorsunuz, doktorlar). With the vowel-final araba, the vowel-initial endings (-Im, -Iz) take a buffer y first (arabayım, arabayız), while the consonant-initial ones (-sIn, -sInIz) attach directly (arabasın, arabasınız).
Doktorum, hastanede çalışıyorum.
I'm a doctor, I work at a hospital.
Öğrenciyiz, sınavlara hazırlanıyoruz.
We're students, we're preparing for exams.
Çok yorgunum, biraz uzanacağım.
I'm very tired, I'm going to lie down for a bit.
The third-person singular is bare
This is the single hardest thing for an English speaker to trust, because English must say is. In Turkish, o "he/she/it" takes no copular ending at all in the present. The predicate just sits there:
- Bu ev güzel. "This house is nice."
- O çok zeki. "He/she is very clever."
- Hava soğuk. "The weather is cold."
There is nothing between the subject and the predicate. Adding a word for "is," or sticking an ending on the predicate to mark third person, is the classic beginner error. The bare predicate is the full sentence.
Bu ev çok güzel, bahçesi de büyük.
This house is very nice, and its garden is big too.
Kardeşim hâlâ çok küçük.
My sibling is still very little.
The buffer y after vowels
The first-person endings start with a vowel — -Im, -Iz — so when the predicate already ends in a vowel, Turkish slips in a buffer y to keep two vowels from colliding. This is the same buffer you meet across the whole language.
- araba "car" → araba
- y
- ım = arabayım "I'm a car" (e.g., in a children's game)
- y
- öğrenci "student" → öğrenci
- y
- im = öğrenciyim "I'm a student"
- y
- hasta "sick" → hastayım "I'm sick"
The consonant-initial endings (-sIn, -sInIz) never need the buffer, because no clash arises: öğrencisin "you're a student," not öğrenciysin.
Öğrenciyim, henüz çalışmıyorum.
I'm a student, I don't work yet.
Bugün biraz hastayım, dışarı çıkmayacağım.
I'm a bit sick today, I won't go out.
Asking questions: the mı particle
To make a yes/no copular question, use the separate, harmonizing particle mı / mi / mu / mü — written as its own word — and hop the person ending onto it. "Are you ready?" is Hazır mısın?; "Are you (pl.) ready?" is Hazır mısınız?
Neredesin? Seni göremiyorum.
Where are you? I can't see you.
Hazır mısınız? Yola çıkmamız lazım.
Are you all ready? We need to get going.
Note that neredesin "where are you" already contains the -sin ending on nerede "where (LOC.)" — questions with a question word (where, who, what) don't need the mı particle; only yes/no questions do. The particle always stays a separate word: hazır mısın, never hazırmısın.
The optional -DIr: formal and generic
In the third person, the bare predicate is the everyday norm. But formal and written Turkish can add -DIr (harmonizing, and hardening to -tır/-tir/-tur/-tür after a voiceless consonant) to mark a statement as general, definitional, or official. Türkiye büyük "Turkey is big" (plain) vs. Türkiye büyüktür "Turkey is large" (formal, encyclopedic). You meet -DIr on signs, in definitions, in scientific prose, and in confident generalizations. It sounds stiff in casual chat — see the -DIr suffix for the full nuance.
Su, yüz derecede kaynar; bu bir gerçektir.
Water boils at a hundred degrees; this is a fact.
Sigara içmek yasaktır.
Smoking is forbidden.
How this differs from English
English packs the copula into a separate verb that must agree and must appear: I *am, you are, she is. Turkish fuses that information into a suffix on the predicate and, for *she/he/it, uses silence. Three habits to drop: (1) don't insert a "be" word; (2) don't add anything for third-person is; (3) don't forget the buffer y on vowel-final predicates. The endings themselves are just the four-way harmony you already know, applied to -Im / -Iz — there is very little new machinery, only a new instinct.
Common mistakes
❌ Ben im doktor.
Incorrect — no standalone 'be'; attach the ending to the predicate: doktorum.
✅ Doktorum.
I'm a doctor.
❌ O güzeldir kız.
Incorrect — in plain speech the 3sg is bare; no -DIr needed: O güzel bir kız.
✅ O güzel bir kız.
She's a pretty girl.
❌ Öğrenciim.
Incorrect — a vowel-final predicate needs the buffer y before -Im: öğrenciyim.
✅ Öğrenciyim.
I'm a student.
❌ Hazırmısınız?
Incorrect — the question particle mı is a separate word: hazır mısınız.
✅ Hazır mısınız?
Are you (all) ready?
❌ Bu ev güzeldir çok.
Off — in casual speech drop -DIr and just say the bare predicate.
✅ Bu ev çok güzel.
This house is very nice.
Every mistake traces back to the same source: an English-speaker reflex to supply or mark "is/am/are." Trust the suffix, leave the third person bare, and remember the buffer y.
Key takeaways
- The present copula is a set of person endings on the predicate: -(y)Im, -sIn, -Ø, -(y)Iz, -sInIz, -lAr — doktorum, doktorsun, doktor, doktoruz, doktorsunuz, doktorlar.
- The third-person singular has no ending: Bu ev güzel "This house is nice."
- Insert the buffer y before the vowel-initial endings on a vowel-final predicate: araba → arabayım, öğrenci → öğrenciyim.
- Yes/no questions use the separate particle mı/mi/mu/mü with the person ending on it: Hazır mısınız?
- Optional -DIr adds a formal, generic, or official tone in the third person only — see the -DIr suffix.
- These are the same endings you meet on predicate adjectives — see predicative adjectives — and the present slot of the wider copula system.

- The Copula System: 'To Be' Without a VerbA1 — Turkish has no verb 'to be' to conjugate; instead a set of endings — plus the defective particle i- for the past, evidential, and conditional — cliticizes onto the predicate, and the present 'is' is often nothing at all.
- Predicative Adjectives and the Zero CopulaA1 — When an adjective is the predicate of a sentence, it carries the copular person ending directly — there is no separate verb 'to be' in the present, so 'I am happy' is simply mutluyum.
- The -DIr Suffix: Assertion and RegisterB2 — The third-person copular -DIr is optional in everyday Turkish but adds formality, marks generic truths, and signals confident inference ('must be') — common in encyclopedic and scientific prose, yet stilted in casual conversation.
