Pronouns, Sentence Structure

Use the French interrogative pronouns qui, que, quoi, and lequel to ask questions:

  • Use qui(who) to ask about people.

  • Use que(what) to ask about things.

  • Use quoi(what) as another form of que in certain settings.

  • Use lequel(which one) to refer to people or things that have been mentioned already.

But have you ever heard someone use the phrase “c’est qui qui…”(Who is it who...)? Or have you ever seen the pronouns auxquelles or duquel? If you’re curious, you’ve come to the right place! In this post, we’ll review how to use the interrogative pronoun qui as the subject and object of a sentence, how to use que as the subject and object of a sentence, when que becomes quoi, and how to use lequel, along with its contractions with the prepositions à(to) and de(of).

Are you ready? Allons-y ! (Let's go!)

    How to use the interrogative pronoun ‘qui’ in French?

    Use the French interrogative pronoun qui(who / whom) to ask questions about people. You can use qui as the subject or the object.

    How to use ‘qui’ as the subject of a question in French?

    Use qui as the subject of a question to express “who.” You can either use qui on its own or with the phrase qui est-ce qui.

    Qui est-là ?

    Who is here?

    Qui is the subject of the verb est.

    Qui est-ce qui fait ce bruit ?

    Who is making this noise?

    Just like in English, when you ask a question with “who,” the verb (fait / est) is always conjugated in the third person singular (il / elle / on) form.

    Tip

    Qui est-ce qui can be a bit “heavy,” so you might prefer to stick with qui on its own.

    Important

    To create a question in French using qui, follow one of these two word orders:

    • Qui

      verb
      (in the 3rd person singular)

      object

      Qui prend la photo ?

      Who is taking the photo?

    • Qui est-ce qui

      verb
      (in the 3rd person singular)

      object

      Qui est-ce qui arrosera les plantes ?

      Who will water the plants?

    No other word order is possible when qui is the subject.

    How to use ‘qui’ as the subject in informal speech in French?

    In informal speech, you use qui to ask about a subject using one of these strange phrases:

    • Qui c’est qui …?

    • C’est qui qui …?

    Both of these phrases mean “who is it who?” Although they are not very elegant, they are used a lot. I can even tell you that I heard a certain French president use them quite a few times!

    C'est qui qui a mis les verres dans le lave-vaisselle ?

    Who put the glasses in the dishwasher?

    The following diagram shows different ways to use qui in the question "who called?" depending on formality:

    MOST FORMAL

    Qui est-ce qui a téléphoné ?

    Qui a téléphoné ?

    Qui c'est qui a téléphoné ?

    C'est qui qui a téléphoné ?

    LEAST FORMAL

    When to use ‘qui’ as the object of a question in French?

    We use the interrogative pronoun qui as an object in order to say “whom,” and it is only used when referencing people.

    subject

    verb

    qui

    Tu préfères qui ?

    Whom do you prefer?

    There are several word order combinations possible, depending on the formality of the question. The graphic below illustrates various ways to ask, “Who are you looking for?”:

    MOST FORMAL

    qui + verb + subject:

    Qui cherchez-vous ?

    qui + est-ce que+ subject + verb:

    Qui est-ce que vous cherchez ?

    subject + verb + qui:

    Vous cherchez qui ?

    LEAST FORMAL

    How to use the interrogative pronoun ‘que’ in French?

    Use the interrogative pronoun que as the subject or object of a sentence in French. We use que to ask questions about things or ideas, like you would use the word “what,” in English.

    Tip

    Note that que becomes qu' in front of a vowel, unlike qui.

    How to use ‘que’ for subjects in French?

    Use que to ask about a “what thing” or “what idea” is the subject in some situation. When you use que for the subject in French, you must use it in combination with est-ce qui, like this: qu’est-ce qui. This phrase literally means “what is it that...”

    qu’est-ce qui

    verb in the 3rd person singular

    object

    Qu’est-ce qui s’est passé à l’aéroport ?

    What has happened at the airport?

    Qu’est-ce qui arrivera à Anthony ?

    What will happen to Anthony?

    Notice that the answer to both of these questions will be the subject of a sentence.

    Now, let’s see what to do when que is the object of a sentence.

    How to use ‘que’ for objects in French?

    Use que as the object of a sentence when you want to ask “what thing” or “what idea” someone is acting upon or if you want to ask what something is. You can use que as an object in a few different ways:

    • Use Qu’est-ce + que + subject + verb to make it clear that you are asking a question!

      Qu’est-ce que tu regardes ?

      What are you watching?

      Qu’est-ce que c’est ?

      What is it?

      Qu’est-ce qu’il y a ?

      What’s the matter?

    • Que on its own is less common and much more formal.

      Que s’est-il passé à l’aéroport ?

      What happened at the airport?

      Que mangez-vous ?

      What are you eating?

      Que portent-ils ?

      What are they wearing?

    • In an informal question, que becomes quoi. (See the next section!)

    The chart below will show you the difference in formality between the three ways to ask “What are you doing?”

    MOST FORMAL

    Que fais-tu?

    Qu'est-ce que to fais ?

    Tu fais quoi ?

    LEAST FORMAL

    Tip

    My students often get confused with the several ways of asking questions in French. My advice is to stick with (Qu’)est-ce que, as it is perfect for all situations.

    Now that you know the rule, try this exercise and see if you can choose between qui or que.

    When does ‘que’ become ‘quoi’ in French?

    The interrogative pronoun que will become quoi in informal French sentences when it is placed after the verb. Look at the two sentences below. What do you notice?

    Que veux-tu ?

    What do you want?

    Tu veux quoi ?

    What do you want?

    que becomes quoi after a verb.

    Keep this rule in mind when forming your questions.

    Tu fais quoi ce weekend ?

    What are you doing on the weekend?

    Tip

    Using this word order in spoken French is the most common and also the least formal.

    You can also use quoi as an interjection. To practice sounding like a native speaker and to learn more about using quoi as a French interjection, check out our activity sheet! Or, study this list of common French expressions using quoi.

    When to use ‘que’ and ‘qui’ with prepositions in French?

    Use que and qui with prepositions when the verb of your question takes a preposition, usually à or de. When you use verbs that take a preposition, you will use this preposition in combination with que and qui.

    When you use a preposition with que, something magical happens...
    It becomes quoi!

    que becomes quoi after a preposition.

    Verb + preposition
    Question with quoi

    penser à

    to think about

    À quoi penses-tu ?

    What are you thinking about?

    avoir peur de

    to be scared of

    De quoi tu as peur ?

    What are you scared of?

    appuyer sur

    to press

    J’appuie sur quoi ?

    What am I pressing on?

    Qui with the prepositions à and de means "whom," but it does not change form like que:

    Verb + preposition
    Question with qui

    parler à

    to talk to

    À qui tu parles ?

    To whom are you talking?

    parler de

    to talk about

    De qui tu parles ?

    About whom are you talking?

    Tip

    Keep in mind that the order of the words is flexible. For example, above, you could also say, “Tu penses à quoi ?” or “Sur quoi j’appuie ?” or “À qui parles-tu ?”

    Here is a list of French verbs with their prepositions that you might find useful.

    Important

    Always make sure the preposition is placed just before the interrogative pronoun qui or quoi, regardless of the word order you choose to use.

    Qui est-ce que tu habites avec ?
    → Avec qui est-ce que tu habites ?

    Whom do you live with?

    So now you can ask “who,” “whom,” or “what” in French. But do you know how to say “which one”? Let’s learn about lequel!

    How do you use the interrogative pronoun ‘lequel’ in French?

    Use the interrogative pronoun lequel(which one) to refer to people or things that have been previously mentioned.

    - Je vais acheter une casquette.

    I’m going to buy a cap.

    - Laquelle tu vas choisir ?

    Which one are you going to choose?

    Why am I using laquelle in this example? Because this interrogative pronoun must agree with the number and gender of the noun it replaces. In other words, check if your noun is singular or plural, and masculine or feminine, and follow this table to choose the right form of lequel:

    Gender
    Number
    Form of lequel

    masculine

    singular

    lequel

    plural

    lesquels

    feminine

    singular

    laquelle

    plural

    lesquelles

    Tip

    Sometimes, you will hear the interrogative word quel and its variants. This interrogative typically modifies another noun in the sentence, and it is different from lequel . Read our article on forming questions to learn more about using quel in French questions!

    In my previous example, I was replacing une casquette (feminine and singular), so I used the interrogative pronoun laquelle.

    Let’s try another example together:

    - J’ai perdu mes clés.

    I lost my keys.

    - ____________?

    Which ones?

    ↳ hint: la clé

    - Les clés de la maison !

    The house keys!

    Have you worked out which form to use here? Well done! Les clés is a feminine plural noun, therefore we replace it with lesquelles.

    Before we wrap up, let’s review one last tricky part of using lequel. Sometimes, lequel will form a contraction with the prepositions that precede it. Let’s take a look.

    How do prepositions change the form of ‘lequel’ in French?

    Prepositions change the form of lequel in French by forming contractions with the interrogative pronoun. If you use lequel with the prepositions à or de, it contracts with these prepositions.

    Example:

    de

    lequel

    =

    duquel

    Pay attention to the sentence below in which the noun is mentioned, and check if the verb uses a preposition.

    - Je vais parler à mon ami.

    I’m going to speak to my friend.

    - Auquel ? Maxence ou Gaspard ?

    Which one? Maxence or Gaspard?

    The verb is parler à, so lequel is combined with à to become auquel. Here are some more example sentences.

    The following table shows how to use lequel in combination with the two most frequent prepositions: à and de.

    preposition + lequel
    singular
    plural
    masculine
    feminine
    masculine
    feminine

    without a preposition

    lequel

    laquelle

    lesquels

    lesquelles

    à + lequel

    aquel

    à laquelle

    auxquels

    auxquelles

    de + lequel

    duquel

    de laquelle

    desquels

    desquelles

    For other prepositions like contre(against), pour(for), etc., simply place the preposition in front of the form of lequel you need to use. For example:

    Pour lesquelles ?

    For which ones?

    Contre laquelle ?

    Against which one?

    Now, let’s review the main points that we have covered in this post.

    Let’s recap

    In this post, we’ve covered how to use the interrogative pronouns qui, que, quoi, and lequel.
    Recall the following:

    • Here is how to use qui / que / quoi:

      who

      qui

      qui est-ce qui

      whom

      qui

      qui est-ce que

      what

      que

      qu’est-ce que

      qu’est-ce qui

      quoi*

      * (Use quoi to say “what” after a verb in an informal question or after a preposition.)
    • When using a verb that takes a preposition, always keep the preposition before the interrogative pronoun (à qui, de quoi….

    • Here is how to use lequel:

      • Lequel refers to people and things that have been previously mentioned.

      • Lequel has to agree with the noun it represents.

      • Lequel takes different forms when used with the preposition à and de (auxquelles, duquel, etc.).
