Predicative "To Be": How Turkish Says "I Am" Without a Verb

In English, “to be” is a full verb that stands on its own — “I am,” “you are,” “she is.” In Turkish, when “to be” is just linking a subject to a noun or adjective in the present tense, it isn’t a separate word at all. It’s a personal suffix that attaches directly to the end of the predicate.

What these endings do

A predicative sentence in Turkish — “I am tired,” “You are a teacher,” “We are ready” — needs no verb “to be.” Instead, the noun or adjective itself carries a small suffix that tells you who the subject is:

• Yorgunum. — I am tired.
• Öğretmensin. — You are a teacher.
• Hazırız. — We are ready.

Drop the suffix and you’re left with a bare adjective or noun, not a sentence. The suffix is doing all the work English hands to “am/are/is.”

Forming it

The full set of personal endings for the present-tense predicative, by person and by the vowel harmony class of the noun/adjective’s last vowel:

For example: hasta (“sick,” last vowel a) gives hastayım (I am sick) and hastasın (you are sick) — reading straight down the a, ı column.

If the predicate ends in a vowel, a buffer -y- appears before the 1st-person and 1st-person-plural endings so two vowels don’t collide directly — that’s the “(y)” in -(y)ım and -(y)ız:

• hasta (sick) → hastayım (I am sick) — vowel-final, buffer needed
• öğretmen (teacher) → öğretmenim (I am a teacher) — consonant-final, no buffer

The second-person and second-person-plural endings (-sın, -sınız) already start with a consonant, so they never need a buffer — they attach directly either way.

Exceptions worth knowing

Third person takes no suffix in ordinary speech. O yorgun (“he/she is tired”) and o öğretmen (“he/she is a teacher”) are complete sentences with nothing added after the predicate. There is a formal third-person suffix, -dir/-dır/-dur/-dür (or -tir, etc. after a hard consonant), but everyday speech mostly leaves it off; you’ll mainly meet it in written, formal, or definitional statements — dictionary-style claims, official announcements, generalizations — like İstanbul büyük bir şehirdir. (“Istanbul is a large city.”)

Negation uses değil, not a suffix on the predicate itself. To say a predicative sentence is false, you place the separate word değil (“not”) right after the noun or adjective, and the personal ending moves onto değil instead:

• Yorgun değilim. — I am not tired.
• Öğretmen değilsin. — You are not a teacher.
• O yorgun değil. — He/she is not tired. (third person: still no suffix)

Questions use the particle mı/mi/mu/mü, and the personal ending moves there too. The question particle is a separate word placed right after the predicate, itself chosen by vowel harmony from the predicate’s last vowel, and the personal suffix attaches to it rather than to the noun or adjective:

• Yorgun musun? — Are you tired?
• Öğretmen miyim? — Am I a teacher?
• O yorgun mu? — Is he/she tired? (third person: bare particle, no suffix)

Examples

• Çok mutluyum. — I am very happy.
• Sen gerçekten çok yorgunsun. — You are really very tired.
• O bir doktor. — He/she is a doctor.
• Biz bu akşam hazırız. — We are ready this evening.
• Siz çok naziksiniz. — You (plural/formal) are very kind.
• Ali burada değil. — Ali is not here.

Notice how each sentence’s ending changes with the subject, while the third-person examples (o bir doktor, Ali burada değil) carry no personal suffix at all — the absence itself marks the third person.

Babi, Speafy’s AI tutor, will drill you across all five forms — swapping ben, sen, o, biz, and siz under the same adjective — until the right vowel-harmony ending comes out automatically, and Speafy’s FSRS-based flashcards make sure the “no suffix at all” third-person pattern sticks just as firmly as the ones that do take an ending.
