Formal questions with inversion

Viens-tu ?Are you coming?

There's a third, more formal way to ask a question in French, alongside rising intonation and est-ce que: swapping the subject and the verb. It's called inversion — a construction you'll meet in writing, in polite or professional speech, and in a good number of set expressions, all more formal than everyday conversation.

Quick shortcut: swap the pronoun and the verb, and join them with a hyphen — Tu viens becomes Viens-tu ?

The basic pattern: swap and hyphenate

With a pronoun subject, inversion swaps the verb and the pronoun and links them with a hyphen:

• Tu viens. → Viens-tu ? (Are you coming?)
• Vous parlez français. → Parlez-vous français ? (Do you speak French?)
• Nous pouvons entrer. → Pouvons-nous entrer ? (Can we come in?)
• Ils sont prêts. → Sont-ils prêts ? (Are they ready?)

The verb still agrees with the subject exactly as usual — inversion only reorders the two words, it doesn't change the conjugation.

The linking -t-

When the verb ends in a vowel and the subject is il, elle, or on, French inserts a linking -t- between them, so two vowels never meet:

• Il parle. → Parle-t-il ? (Does he speak?)
• Elle a un chat. → A-t-elle un chat ? (Does she have a cat?)
• On va au cinéma. → Va-t-on au cinéma ? (Are we going to the cinema?)

If the verb already ends in -t or -d, no extra letter is needed — the sound is already there:

• Il vient. → Vient-il ? (Is he coming?)
• Elle part demain. → Part-elle demain ? (Is she leaving tomorrow?)

✅ Parle-t-il ?, never ❌ Parle-il ? — skipping the -t- after a vowel-ending verb is one of the most common inversion mistakes.

Inversion with a noun subject

For a yes/no question, a noun doesn't usually invert directly with the verb — ❌ Vient Pierre ? sounds odd on its own. Instead, the noun stays in its normal place at the front, and a matching subject pronoun is added after the verb, inverted as usual:

• Pierre vient-il ? (Is Pierre coming?)
• Marie est-elle là ? (Is Marie there?)
• Les enfants sont-ils prêts ? (Are the children ready?)
• Ta sœur a-t-elle appelé ? (Did your sister call?)

The pronoun matches the noun's gender and number — il for a masculine noun, elle for a feminine one, ils for a masculine or mixed plural, elles for an all-feminine plural.

Combining inversion with a question word

A question word can be added in front of an inverted question, exactly the way it's added to a statement:

• Où vas-tu ? (Where are you going?)
• Quand pars-tu ? (When are you leaving?)
• Comment t'appelles-tu ? (What's your name?)
• Pourquoi Marc est-il en retard ? (Why is Marc late?)

With a noun subject after a question word, French formal writing often uses a simpler pattern instead — the noun itself moves after the verb, with no pronoun added:

• Où habite Marie ? (Where does Marie live?)
• Quand arrivent les invités ? (When do the guests arrive?)
• Comment va ton père ? (How is your father?)

This postposed-noun pattern is mostly a written, literary style you'll recognise more than produce at this level. Between the two written patterns, the pronoun one (Marie habite-t-elle… ?) is the safer, more broadly usable choice — but neither is a natural pick for speaking: in everyday conversation, reach for est-ce que (Où est-ce que Marie habite ?) or the casual word order (Marie habite où ?) instead.

A note on je

Inverting je is rare in everyday French — for most verbs, it sounds stiff or literary, and est-ce que is used instead (Est-ce que je parle trop vite ? rather than an inverted form). A handful of common verbs are the exception, including être, avoir, and pouvoir — and pouvoir uses a special inverted form, puis-je, not peux-je:

• Suis-je en retard ? (Am I late?)
• Ai-je le temps ? (Do I have time?)
• Puis-je entrer ? (May I come in?)

When to use inversion

Inversion belongs to formal or written French — a job interview, a letter, a news report, or a polite request to a stranger. In everyday conversation, rising intonation or est-ce que is far more common; hearing a lot of inversion in casual speech would sound unusually formal, almost old-fashioned. Vous inversion, though, shows up often even in fairly ordinary polite exchanges: Avez-vous une réservation ? (Do you have a reservation?) is completely natural from someone like a hotel receptionist.

Common mistakes

• ❌ Parle-il ? → ✅ Parle-t-il ? (a verb ending in a vowel needs the linking -t- before il/elle/on)
• ❌ Vient Pierre ? → ✅ Pierre vient-il ? (a noun subject can't invert directly — keep the noun in place and add the matching pronoun after the verb)
• ❌ Viens tu ? → ✅ Viens-tu ? (the hyphen between the verb and the pronoun is required, not optional)

Quick check

Rewrite each sentence as an inverted question.

1. Tu parles anglais.
2. Il habite à Paris.
3. Marie aime le café.
4. Vous avez fini.

Key takeaways

• Inversion swaps the subject pronoun and the verb, joined by a hyphen — Tu viens becomes Viens-tu ?
• Insert a linking -t- between the verb and il/elle/on when the verb ends in a vowel — Parle-t-il ?, not Parle-il ?
• For a yes/no question, a noun subject usually stays in place, with the matching subject pronoun inverted after the verb — Pierre vient-il ?, not Vient Pierre ?
• A question word can combine with inversion the same way it combines with a statement — Où vas-tu ? With a noun subject, formal writing often postpones the noun itself instead — Où habite Marie ?
• Inverting je is rare and mostly limited to a handful of common verbs, including the special form puis-je for pouvoir.
• Inversion belongs to the formal register — everyday spoken French reaches for intonation or est-ce que instead, though vous inversion is common even in ordinary polite exchanges.
