French question words are the small but mighty tools that let you ask for directions, order food, make friends, and understand the world around you in French. Whether you want to know who, what, when, where, why, or how, mastering these words unlocks real conversation faster than almost any other grammar topic. In this guide, you will learn every essential interrogative, how to pronounce it, and how to build natural questions like a native speaker.
We go deeper than a simple vocabulary list. You will find pronunciation guidance, formal versus casual structures, common mistakes, and practical example sentences you can use today. Let’s dive in.
What Are French Question Words?
French question words, called les mots interrogatifs, are the words that introduce a question and signal what kind of information you want. They function much like their English counterparts, but their placement in a sentence is often more flexible.
There are two broad categories. First, yes/no questions, which do not need a specific question word. Second, information questions, which require an interrogative like qui (who) or où (where).
Below is a quick-reference table of the core French question words every learner should memorize.
| French | English | Pronunciation (approx.) | Example |
|---|---|---|---|
| Qui | Who | kee | Qui est-ce ? (Who is it?) |
| Que / Quoi | What | kuh / kwah | Que fais-tu ? (What are you doing?) |
| Quand | When | kahn | Quand arrives-tu ? (When do you arrive?) |
| Où | Where | oo | Où habites-tu ? (Where do you live?) |
| Pourquoi | Why | poor-kwah | Pourquoi ? (Why?) |
| Comment | How | koh-mahn | Comment ça va ? (How are you?) |
| Combien | How much / many | kohn-byan | Combien ça coûte ? (How much is it?) |
| Quel(le)(s) | Which / What | kel | Quelle heure est-il ? (What time is it?) |
How to Use French Question Words in Real Sentences
Knowing the words is only half the battle. The magic happens when you slot them into natural sentence patterns. French offers three main ways to ask a question, ranging from casual to formal.
1. Intonation (the casual way)
The simplest method is to keep normal word order and raise your voice at the end. This is extremely common in spoken French.
- Tu viens ? — You’re coming? (rising tone)
- Il est où ? — Where is he? (question word placed at the end)
2. Est-ce que (the everyday middle ground)
Add est-ce que before a statement to form a clear question without changing word order. Pair it with a question word for information questions.
- Où est-ce que tu habites ? — Where do you live?
- Pourquoi est-ce qu’il part ? — Why is he leaving?
3. Inversion (the formal way)
Flip the subject and verb, joining them with a hyphen. Reserve this for writing, interviews, or polite speech.
- Comment allez-vous ? — How are you? (formal)
- Quand partez-vous ? — When are you leaving?
The Tricky Ones: Que, Quoi, and Quel
Learners often stumble on the three words that all translate loosely as “what.” Each behaves differently, so let’s separate them clearly.
| Word | Role | Position | Example |
|---|---|---|---|
| Que | “What” as an object, before a verb | Start of question | Que veux-tu ? (What do you want?) |
| Quoi | “What” after a preposition or at sentence end | End / after preposition | Tu penses à quoi ? (What are you thinking about?) |
| Quel(le) | “Which/what” describing a noun | Before a noun; agrees in gender/number | Quel livre ? (Which book?) |
Notice that quel is an adjective, so it must agree: quel (masculine), quelle (feminine), quels and quelles (plural). This agreement trips up many students, so practice it out loud.

Pronunciation Tips for French Question Words
Correct pronunciation makes your questions instantly understandable. Here are practical tips drawn from years of tutoring experience.
- Silent letters: The final -d in quand and -t in comment are silent unless followed by a vowel (liaison).
- Liaison: In Quand est-il ?, the d links and sounds like a t: “kahn-t-eh-teel.”
- The French “u”: Où uses a rounded “oo,” while tu uses a tighter “ew” sound. Mixing them changes your meaning.
- Nasal vowels: Combien and quand end in nasal sounds. Let the air pass through your nose without pronouncing a hard “n.”
To hear authentic audio, check the pronunciation entries on Wiktionary, a reliable open dictionary maintained by language experts.
Common Mistakes to Avoid
Even confident learners repeat a handful of predictable errors. Watch for these:
- Using que at the end of a sentence. Say Tu fais quoi ?, never Tu fais que ?
- Forgetting quel agreement. Match the gender and number of the noun every time.
- Overusing inversion in casual chat. Native speakers rarely invert in everyday conversation; est-ce que feels more natural.
- Mispronouncing où versus ou. With the accent, it means “where”; without, it means “or.” Both sound identical, so context is key.
According to Wikipedia’s overview of French grammar, interrogative structures are among the first patterns learners internalize, precisely because they appear in every conversation.
Practice: Build Your Own Questions
The fastest way to remember French question words is to use them immediately. Try transforming these statements into questions using all three methods.
- Tu manges au restaurant. → Où manges-tu ? / Où est-ce que tu manges ? / Tu manges où ?
- Elle arrive demain. → Quand arrive-t-elle ?
- Le film coûte dix euros. → Combien coûte le film ?
Repeat each version aloud until it feels automatic. Consistent daily practice beats occasional cramming, and a tutor can correct your errors in real time. Explore structured lessons on The Cognitio blog to keep building momentum.
Frequently Asked Questions
What are the main French question words?
The main French question words are qui (who), que/quoi (what), quand (when), où (where), pourquoi (why), comment (how), combien (how much/many), and quel (which). Together they cover almost every question you will ever need to ask.
What is the difference between que and quoi?
Both mean “what,” but que comes at the start of a question before a verb, while quoi follows a preposition or ends a casual question. For example, Que fais-tu ? and Tu fais quoi ? both mean “What are you doing?”
How do you ask a question politely in French?
Use inversion or est-ce que with the formal vous form. For instance, Comment allez-vous ? (“How are you?”) sounds respectful, while Comment ça va ? is casual and used with friends and family.
Do French question words change based on gender?
Most do not, but quel does. As an adjective, it becomes quel, quelle, quels, or quelles to match the gender and number of the noun it describes, such as Quelle heure est-il ?
