French Question Words: The Ultimate Guide to Asking Questions

Knowing how to ask questions is essential when learning any new language. Whether you need directions in Bordeaux, want to strike up a chat with a native speaker, or are taking an official DELF exam, mastering French question words (les mots interrogatifs) is an indispensable milestone.

In this practical guide, we will break down all essential French question words, clarify tricky distinctions like que versus quoi, and explain the three grammatical registers used to ask questions in French.

Here is a handy summary table of the primary French interrogative words:

2. In-Depth Breakdown of French Question Words

Qui (Who / Whom)

French Word English Meaning Example Sentence English Translation
:--- :--- :--- :---
Qui Who / Whom Qui est à l'appareil ? Who is on the phone?
Que / Quoi What Que dis-tu ? / Tu dis quoi ? What are you saying?
Où Where Où vas-tu ? Where are you going?
Quand When Quand arrive le train ? When does the train arrive?
Pourquoi Why Pourquoi souris-tu ? Why are you smiling?
Comment How Comment ça marche ? How does it work?
Combien How much / How many Combien de temps reste-t-il ? How much time is left?
Quel(le) Which / What Quel est ton prénom ? What is your first name?
  • Subject: Qui veut du café ? (Who wants coffee?)
  • With prepositions: Pour qui est ce cadeau ? (Who is this gift for?)
  • Object: Qui cherchez-vous ? (Whom are you looking for?)

    • `Qui` is used exclusively for people. It can act as a subject, direct object, or indirect object after a preposition:

    Que, Quoi, and Qu'est-ce que (What)

  • Que: Used at the beginning of formal sentences with inversion (Que voulez-vous ?).
  • Qu'est-ce que: The standard, everyday form (Qu'est-ce que vous voulez ?).
  • Quoi: Used after prepositions (À quoi penses-tu ?) or at the end of informal sentences (Tu veux quoi ?).

    • English speakers often struggle with "what" because French uses different words based on sentence position and formality:

    Où (Where)

  • Où se trouve la gare ? (Where is the train station?)
  • D'où viens-tu ? (Where do you come from?)

    • Do not forget the grave accent (`ù`). In French, `où` means "where", while `ou` without an accent means "or".

    Quand (When)

  • Quand partez-vous en vacances ? (When are you leaving on vacation?)

    • `Quand` asks about time, dates, or schedules. Notice that when followed by est-ce que, the final "d" links to the vowel and sounds like a "t" (Quand est-ce que... / kɑ̃.tɛs.kə).

    Pourquoi (Why)

  • Pourquoi apprends-tu le français ? (Why are you learning French?)
  • Parce que je veux travailler en France. (Because I want to work in France.)

    • `Pourquoi` inquires about reasons and intentions. In reply, native speakers usually use parce que (because) followed by a clause, or pour (to / in order to) followed by an infinitive verb:

    Comment (How)

  • Manner: Comment prépare-t-on ce plat ? (How do you prepare this dish?)
  • Greeting: Comment allez-vous ? (How are you?)
  • Name: Comment vous vous appelez ? (What is your name?)

    • `Comment` is used to ask about manner, condition, means of travel, or identity:

    Combien (How Much / How Many)

  • Asking price: Combien coûte cette baguette ? (How much is this baguette?)
  • Quantities: Combien de langues parlez-vous ? (How many languages do you speak?)

    • `Combien` is used for price and quantities. When followed by a noun, always add the preposition de (or d' before a vowel):

    Quel / Quelle / Quels / Quelles (Which / What)

  • Quel (masculine singular): Quel film veux-tu voir ?
  • Quelle (feminine singular): Quelle est ta nationalité ?
  • Quels (masculine plural): Quels jours es-tu libre ?
  • Quelles (feminine plural): Quelles matières étudies-tu ?

    • Unlike the other invariable adverbs, `quel` is an interrogative adjective that must agree in gender and number with the noun it modifies:

    3. How to Form Questions in French: 3 Core Registers

To construct natural sentences, combine question words with one of three French question patterns:

1. Informal (Intonation / End of sentence): Keep subject-verb order and place the question word at the end.

  • Vous partez quand ? (When are you leaving?)

2. Standard (Est-ce que): Place the question word first, followed by est-ce que, then standard subject-verb order.

  • Quand est-ce que vous partez ?

3. Formal (Inversion): Place the question word first, then invert the subject pronoun and verb with a hyphen.

  • Quand partez-vous ?

    • Summary & Next Steps

Learning French question words unlocks meaningful communication right away. Focus first on mastering the `est-ce que` structure, as it works reliably in almost every conversational context without sounding overly formal or excessively slangy.
