Questions & Answers about Çıkış kapalı.
Turkish allows nominal sentences, where a noun or adjective serves as the predicate without an overt to be verb in the present tense for third person. So Çıkış kapalı literally says “exit closed,” which is understood as “The exit is closed.”
- Third-person present copula is zero: Kapı açık (The door is open).
- With other persons, you add a copular ending: Ben öğrenciyim (I am a student), Biz kapalıyız (We are closed — e.g., on a shop sign).
The suffix -(d)Ir is an optional copular/epistemic marker. You use it for:
- Formal or written style (announcements, reports, signage).
- Emphasis or conveying certainty/generality.
- Disambiguation in complex sentences.
Here, Çıkış kapalıdır is more formal/emphatic than Çıkış kapalı. Vowel harmony applies: since the last vowel of kapalı is ı, you get -dır → kapalıdır.
- Yes/no question: add the question particle (written separately) with vowel harmony: Çıkış kapalı mı?
- Negative (with adjectives): use değil: Çıkış kapalı değil (The exit is not closed).
- Antonym: Çıkış açık (The exit is open).
