Historical Context & Motivation
Every language faces the same basic challenge: how do you avoid repeating the same nouns over and over again? In English, you swap out names for pronouns—"I gave her the book" instead of "I gave Marie the book." French has been doing the same thing for over a thousand years, and its system of indirect object pronouns is one of the most elegant results of that evolution. Understanding how these pronouns developed helps explain why they work the way they do today.
So the core question this lesson addresses is straightforward: when someone in a sentence is the recipient of an action—the person you're giving something to, talking to, or doing something for—how do you replace that person with a pronoun in French? The answer lies in mastering lui and leur.
Core Principles & Definitions
Before diving into examples, let's nail down the key ideas you need. An indirect object is the person or thing that receives the direct object or benefits from the action of the verb. In English, it is often introduced by the preposition "to" or "for." In French, indirect objects are introduced by the preposition à ("to"). An indirect object pronoun (un pronom complément d'objet indirect) replaces that "à + person" phrase so you don't have to keep repeating it.

Choose the Right Pronoun
Place It Before the Verb
Look for à + Person Verbs
Visual Explanation — Sentence Transformation
The diagram below shows exactly what happens when you transform a sentence from using a full indirect object noun to using a pronoun. Pay attention to how the pronoun slides in front of the verb and the "à + person" phrase disappears entirely.
Notice that the pronoun lui works for both masculine and feminine singular indirect objects. Whether you're talking to Marie or to Paul, the pronoun is the same: lui. This is different from direct object pronouns (le/la), which do change based on gender. When the indirect object is plural—"to them"—you switch to leur, regardless of whether the group is all male, all female, or mixed.
How It Works — Placement Rules
The placement of lui and leur follows a consistent pattern. In a simple present-tense sentence, the pronoun always goes directly before the conjugated verb. In the negative, the pronoun stays sandwiched between ne and the verb. Let's look at the placement formulas.
Common Verbs That Take Indirect Objects
Not every verb uses an indirect object. The key is to look for verbs that are followed by à + a person. Below is a table of the most common verbs you'll encounter in French 2 that naturally pair with lui and leur. Memorizing these will make pronoun replacement almost automatic.
| French Verb | English Meaning | Example with lui | English Translation |
|---|---|---|---|
| parler à | to speak to | Je lui parle. | I speak to him/her. |
| donner à | to give to | Elle lui donne un cadeau. | She gives him/her a gift. |
| dire à | to say/tell to | Il leur dit la vérité. | He tells them the truth. |
| téléphoner à | to call (phone) | Nous lui téléphonons. | We call him/her. |
| écrire à | to write to | Tu leur écris une lettre. | You write them a letter. |
| envoyer à | to send to | Je lui envoie un message. | I send him/her a message. |
| demander à | to ask (of) | Je lui demande de l'aide. | I ask him/her for help. |
| répondre à | to answer/respond to | Elle leur répond. | She answers them. |
Worked Example — Step by Step
Let's walk through a complete example, step by step, to see how to identify the indirect object and replace it with the correct pronoun.
Direct vs. Indirect Object Pronouns
One of the biggest sources of confusion in French 2 is mixing up direct object pronouns (le, la, les) with indirect object pronouns (lui, leur). Both go before the verb, and both replace nouns. The table below breaks down the key differences so you can tell them apart every time.
| Feature | Direct Object Pronouns | Indirect Object Pronouns |
|---|---|---|
| Question to ask | "What?" or "Whom?" (no preposition) | "To whom?" or "For whom?" |
| Preposition | None — verb connects directly to the object | à (to) connects the verb to the person |
| Singular pronouns | le (him/it masc.), la (her/it fem.) | lui (to him OR to her) |
| Plural pronoun | les (them) | leur (to them) |
| Gender distinction? | Yes — le (masc.) vs. la (fem.) | No — lui for both masc. and fem. |
| Example | Je le vois. (I see him.) | Je lui parle. (I talk to him/her.) |
Connection to Advanced Pronoun Usage
Mastering lui and leur in the present tense is a crucial foundation. As you advance in French, you'll encounter these same pronouns in more complex structures. The table below previews what's ahead so you can see where today's lesson fits in the bigger picture.
| What You Know Now | What's Coming Next |
|---|---|
| lui/leur in present tense affirmative sentences | lui/leur in passé composé (past tense): Je lui ai parlé. |
| lui/leur in simple negatives | Double object pronouns: using a direct AND indirect pronoun in the same sentence (Je le lui donne.) |
| lui/leur with one infinitive (Je vais lui parler) | Pronoun placement in imperative (command) forms: Donne-lui le livre ! |
| Replacing à + a specific person | The pronoun y replacing à + a place or thing (not a person) |
The good news is that the core logic stays the same: identify the indirect object, pick lui or leur, and place it before the relevant verb. Once you lock in this pattern now, extending it to new tenses and more complex sentence structures will feel like a natural next step rather than something entirely new.

Lesson Summary
French indirect object pronouns replace the à + person phrase in a sentence to avoid repetition. Use lui when referring to one person (him or her—no gender distinction), and use leur when referring to multiple people (them). Both pronouns are placed before the conjugated verb in affirmative and negative sentences. When a modal or semi-auxiliary verb (like aller, vouloir, pouvoir, or devoir) is followed by an infinitive, the pronoun goes before the infinitive instead.
To decide between a direct and indirect object pronoun, ask whether the verb uses the preposition à before the person. Common verbs that require lui/leur include parler à, donner à, dire à, téléphoner à, écrire à, envoyer à, and demander à. Mastering this pattern now sets you up for success with past-tense pronoun placement, double object pronouns, and imperative commands in future lessons.
