Copula Questions and Negatives in Full

You already know how to say "I am a teacher" — öğretmenim — with the present copula endings. This page drills the other two things you do with "be" sentences constantly: asking them ("Are you a teacher?") and negating them ("I'm not a teacher"). The good news is that both reuse a single pattern across every predicate, noun or adjective. Questions put the person ending on the particle mI; negatives put the same endings on the word değil. Master one full grid of each — a noun and an adjective — and you can question or negate any "be" sentence in the language.

Questions: the ending hops onto mI

In a statement, the person ending sits on the predicate: öğretmensin "you are a teacher." In a question, the predicate goes bare and the ending moves onto the separate particle mI: öğretmen misin? "are you a teacher?" The structure is Predicate + mI + person-ending, and the particle mI is the new host. Here is the full grid for the noun öğretmen "teacher":

Three things to notice. In the ben and biz rows, the ending begins with a vowel (-Im, -Iz), and since mi ends in a vowel too, the buffer y appears: mi + y + im = miyim, mi + y + iz = miyiz. The o row is just bare mi — third person has no ending. And in the onlar row, the plural -lAr stays on the predicate (öğretmenler) and only mi follows.

The same grid on an adjective

The pattern is identical with an adjective predicate. Here is hazır "ready" — note how the vowel harmony of mI changes because the preceding vowel changes:

The only difference from the öğretmen grid is the vowel of the particle: after öğretmen (front, unrounded) it is mi-, after hazır (back, unrounded) it is mı-. The particle harmonizes four ways to the vowel before it: mı / mi / mu / mü. So yorgun (back, rounded) gives yorgun musun? "are you tired?", and mutlu (back, rounded) gives mutlu musun? "are you happy?"

Negatives: the same endings ride on değil

To negate a "be" sentence, Turkish does not put -mA on the predicate — -mA negates verbs only. Instead it uses the separate, invariant word değil "not," and the present copula endings attach to değil, exactly as they would to a noun. So "I am not a teacher" is öğretmen değilim: predicate, then değil, then the ending.

Notice that değil never changes — there is no vowel harmony on it, because its vowels (e, i) are fixed. Only the ending after it harmonizes, and since değil ends in -l (a consonant), the vowel-initial endings (-im, -iz) attach directly with no buffer y: değilim, değiliz — never değiliyim. The third-person singular is bare değil, mirroring the bare predicate in the affirmative.

The negative on an adjective

Again identical with an adjective. Here is hazır "ready":

The endings are exactly the same as on öğretmen değil — proof that değil simply replaces the predicate as the host. Whatever ending you'd put on the noun, you put on değil instead.

Negative questions: değil + mI

To ask a negative "be" question — "Aren't you…?" — you combine değil with the particle mI: değil misin? "aren't you?", değil miyiz? "aren't we?" The frozen tag değil mi? "isn't it? / right?" is the everyday version you'll use constantly to seek agreement.

Common mistakes

Two English-driven traps recur. First, trying to negate a noun with a verb-style -mA (öğretmenmem) — that suffix is for verbs; use değil. Second, relying on rising intonation the way English does (Evde sin?) instead of the actual particle mI. And always keep mI a separate word with the right harmonized vowel.

Key takeaways

• Questions put the person ending on the separate particle mI, with the predicate bare: öğretmen misin?, hazır mısın? — buffer y in the vowel-initial forms (miyim, miyiz, mıyım, mıyız).
• mI is a separate word with four-way harmony: mı / mi / mu / mü, matched to the last vowel of the word before it.
• Negatives use the invariant word değil plus the same present copula endings: öğretmen değilim, hazır değiliz. değil never harmonizes; the third person is bare değil.
• Because değil ends in -l, the vowel-initial endings attach without a buffer y: değilim, never değiliyim.
• Negative questions combine the two: değil misin? "aren't you?", and the everyday tag değil mi? "right?"
• One pattern covers all predicates — see the wider copula grid for how this slot interacts with past, evidential, and conditional.
