Les Questions Négatives

A negative question is a question that contains a negation: Aren't you coming?, Don't you like it?, Hasn't she arrived? In French, these questions are formed exactly the way you would expect — by wrapping the verb in the standard ne... pas — but they unlock something English does not have at all: a third yes/no answer word, si, used specifically to contradict the negative assumption baked into the question. Learning to deploy si in the right place is one of the small, satisfying refinements that makes A2-level French sound noticeably more native.

This page covers how to form negative questions in all three registers, the oui / non / si answer system, the pragmatic flavor a negative question carries (it usually signals surprise, contradiction, or a polite suggestion), and the common errors English speakers make. Si in particular has no English equivalent — you have to internalize a new category — so this page lingers on it.

Forming negative questions in the three registers

French has three question registers — intonation, est-ce que, and inversion (see sentences/interrogative-three-forms). All three can be negated. The negation always wraps the verb (or the auxiliary in compound tenses) in ne... pas, exactly as in declaratives.

Intonation (informal)

The simplest form: take a negative declarative and raise the pitch at the end. Word order is unchanged. The ne may be dropped in fast casual speech, just as it is in declarative sentences (see register/spoken-vs-written).

In very casual speech, the ne is regularly dropped: Tu viens pas ?, T'as pas faim ?. This is fine in conversation; never in writing or formal speech.

Est-ce que (neutral)

The est-ce que form takes the same negation, wrapped around the embedded verb. The fixed phrase est-ce que itself is never negated.

Inversion (formal)

In the formal inversion form, the negation surrounds the inverted verb-pronoun unit. The ne goes immediately before the verb; the pas goes immediately after the inverted pronoun. The whole construction reads heavy on the page — which is exactly why it is reserved for formal or literary registers.

The euphonic -t- still appears with vowel-initial 3sg pronouns (ne fait-il pas...?, ne va-t-il pas...?; see syntax/t-euphonic).

Oui, non, si: the three-way yes/no system

Here is the feature of negative questions that has no English equivalent. French distinguishes three answers to a yes/no question:

• Oui — yes, used to confirm an affirmative question. Tu viens ? — Oui. (Are you coming? — Yes.)
• Non — no, used to negate either type of question. Tu viens ? — Non. (Are you coming? — No.) and Tu ne viens pas ? — Non. (You're not coming? — No (I'm not).)
• Si — yes, used specifically to contradict the negative assumption in a negative question.

The si slot is the new one. When somebody asks you a negative question — Tu ne viens pas ? (Aren't you coming?) — and you want to push back and say yes, I am coming, you do not say oui. You say si. This is mandatory: replying oui to a negative question is ungrammatical and unambiguously marks you as a non-native speaker.

To say no, I really don't in response to a negative question, you use non:

Here is the three-by-two grid that captures the whole system:

The cleanest mental model: si exists to disagree with a negative. If someone asserts or implies a negative and you want to reject that, si is your tool. Oui is reserved for plain affirmatives. Non covers both cases of no.

The pragmatic flavor: surprise, contradiction, or polite suggestion

Negative questions in French rarely ask a literal yes/no. They almost always carry an extra layer of meaning:

(1) Surprise / confirmation seeking. The speaker assumed something and is checking. Tu n'as pas vu Marie ce matin ? (You didn't see Marie this morning?) implies I expected you would have.

(2) Polite suggestion. A negative question softens a proposal. Vous ne voudriez pas un café ? (Wouldn't you like a coffee?) is more polite than Voulez-vous un café ? — it gives the listener room to refuse without losing face.

(3) Rhetorical / contradictory. Sometimes the speaker is challenging the listener. N'as-tu pas honte ? (Aren't you ashamed?) is rhetorical — it accuses rather than inquires.

The English equivalents — Aren't you...?, Wouldn't you...?, Haven't you...? — carry similar pragmatic loads, so the structural parallel is strong. What differs is the answer system: French speakers respond to all three pragmatic uses with si if they want to contradict.

Negative questions with WH-words

Negative WH-questions combine a question word with a negated verb. All three registers work, with the same pattern as affirmative WH-questions (see questions/wh-questions-overview).

Note that pourquoi + negative is by far the most common WH-negative pattern, since why didn't you...? and why don't you...? are everyday questions.

Other negative particles in questions

The same logic applies with negations beyond ne... pas: ne... rien (nothing), ne... jamais (never), ne... plus (not anymore), ne... personne (nobody). All of these can appear in questions, and the si answer rule applies to all of them.

How English vs French differ

English has no equivalent of si. To contradict a negative question, English speakers usually have to construct a full clause: Aren't you coming? — Yes, I am — with stress on am. The bare yes is ambiguous in English (yes I am or yes I'm not?), which is why English speakers add the auxiliary. French sidesteps this with the dedicated word si, which compresses yes, contrary to your assumption into a single syllable. Once you have it, you may find yourself wishing English had the same tool.

A second contrast: English negative questions are often built with contracted do/does (Don't you like it?). French has no equivalent of do-support, so the negation is purely structural — ne... pas surrounds whatever verb is at hand. This actually simplifies things; the same negation pattern works for every verb.

Common Mistakes

Key Takeaways

Negative questions in French are formed by wrapping the verb in ne... pas across any of the three registers — intonation (Tu ne viens pas ?), est-ce que (Est-ce que tu ne viens pas ?), or inversion (Ne viens-tu pas ?). They typically carry pragmatic weight — surprise, polite suggestion, or rhetorical challenge — rather than asking a literal yes/no. The most distinctive feature for English speakers is the three-way answer system: oui (yes to an affirmative question), non (no to either type), and si (yes to a negative question, contradicting the negative assumption). Si is mandatory; using oui to answer a negative question is ungrammatical. Master si, and you have unlocked one of the small, characteristic refinements of French.
