Bonjour!
In our last lesson, we built a strong foundation for asking "yes/no" questions using intonation, est-ce que, and inversion. This is great for confirming information, but what happens when you need to ask for details?
Today, we'll expand your conversational toolkit significantly. By the end of this lesson, you will be able to use the core French question words: qui (who), que (what), où (where), quand (when), comment (how), pourquoi (why), and combien (how much/many). These are the essential building blocks for asking for specific information, a skill you'll need in every type of conversation, from casual chats to job interviews.
1. The Key Question Words: An Overview
These words, also known as interrogative words, allow you to ask "open questions" that require a specific piece of information in the answer, not just a simple oui or non.
Let's start with a quick visual summary of the most common question words.

Now, let's explore each of these words in more detail to understand their specific uses and nuances.
2. A Closer Look at Each Question Word
To get a solid grasp of each word, I'd like you to read a section from an online guide. It breaks down each word with examples.
French Question Words: Learn How To Ask Questions
The article 'French Question Words: Learn How To Ask Questions' from Busuu provides an excellent, detailed explanation for each of the primary question words.
Please read the section titled 'French Question Words Explained'. It starts with 'Qui (who)' and ends with 'À quoi (of what)'. Pay close attention to the examples and the specific notes on 'Que', 'Quoi', and 'Combien'.
As you read, keep these key points in mind:
-
Qui (Who): Refers only to people. It's invariable, meaning it doesn't change.
- Ex: Qui est là ? (Who is there?)
-
Où (Where): Refers to a place or location.
- Ex: Où est la gare ? (Where is the train station?)
-
Quand (When): Refers to a time or date.
- Ex: Quand est-ce que tu arrives ? (When do you arrive?)
-
Pourquoi (Why): Asks for a reason. The answer typically begins with parce que (because).
- Ex: Pourquoi tu apprends le français ? - Parce que je veux travailler en France. (Why are you learning French? - Because I want to work in France.)
-
Comment (How): Asks about the manner or method. It's also used in the common greeting Comment ça va ? (How are you?).
- Ex: Comment tu viens ? (How are you coming?)
-
Combien (How much/many): Asks about quantity. When followed by a noun, you must use de (or d' before a vowel), never des.
- Ex: Combien de langues parlez-vous ? (How many languages do you speak?)
-
Que / Quoi (What): This is the trickiest pair. The one you use depends on its position in the sentence.
- Use Que (or Qu' before a vowel) at the beginning of a formal question with inversion or with est-ce que.
- Ex: Que faites-vous ? (What are you doing? - Formal)
- Ex: Qu'est-ce que tu manges ? (What are you eating? - Neutral)
- Use Quoi at the end of an informal question, or after a preposition (like avec, de, à).
- Ex: Tu manges quoi ? (What are you eating? - Informal)
- Ex: À quoi tu penses ? (What are you thinking about?)
- Use Que (or Qu' before a vowel) at the beginning of a formal question with inversion or with est-ce que.
3. Putting It All Together: Question Words + Question Structures
Remember the three ways to form a question from our last lesson? You can combine these new question words with those same structures. This allows you to adjust your level of formality, which is key for your goal of navigating both professional and casual settings.
- Formal (Inversion):
Question Word + Verb-Pronoun? - Neutral (Est-ce que):
Question Word + est-ce que + Subject + Verb? - Informal (Intonation):
Subject + Verb + Question Word?
The following video does an excellent job of demonstrating how to use these three structures (referred to as formel, courant, and familier) with question words.
Comment poser une question en français - How to ask questions in French
Let's watch 'Comment poser une question en français' from the Parlez-vous FRENCH channel. It clearly explains how to use question words in different registers of speech.
Watch from 02:33 to 05:07. First, the video explains the three structures using the word 'où'. Then, it highlights special rules for 'pourquoi', 'combien', and 'quoi'. This directly connects to what we just covered.
Here is a summary table based on the video's example with où (where):
| Register | Structure | Example | Translation |
|---|---|---|---|
| Formal | Question Word + Verb-Subject? | Où habitez-vous ? | Where do you live? |
| Neutral | Question Word + est-ce que... ? | Où est-ce que vous habitez ? | Where do you live? |
| Informal | Subject + Verb + Question Word? | Vous habitez où ? | Where do you live? |
As the video noted, Pourquoi is a bit of an exception in informal speech; it usually stays at the beginning of the sentence.
Test your understanding!
Your friend tells you: "Je vais au cinéma ce soir." (I'm going to the cinema tonight.)
You want to ask what film they are going to see. Formulate the question "What are you going to see?" in all three registers (Formal, Neutral, Informal).
Show answer
- Formal: Que vas-tu voir ?
- Neutral: Qu'est-ce que tu vas voir ?
- Informal: Tu vas voir quoi ?
Conclusion
Fantastic work! You have now learned how to ask for the "who, what, where, when, why, and how" of any situation. This is a massive step towards having more meaningful and detailed conversations in French.
Key Takeaways:
- The main question words are qui, que/quoi, où, quand, pourquoi, comment, and combien.
- You can use these words with the three question structures you already know: inversion (formal), est-ce que (neutral), and intonation with the question word at the end (informal).
- Pay special attention to the difference between que (beginning of sentence) and quoi (end of sentence or after a preposition).
- Remember to use combien de when asking "how many" of something.
Next Lesson: You are now perfectly equipped for our next topic: introducing yourself and exchanging basic personal information. You'll be able to ask questions like "What is your name?" (Comment vous appelez-vous ?), "Where do you live?" (Où habitez-vous ?), and "What is your profession?" (Quelle est votre profession ?), and you'll learn how to answer them.
À la prochaine ! (Until next time!)
