The Pronoun "Lui" vs. "Le" in French: When to Use Each

There are certain French grammar mistakes I hear so often from English-speaking students that I can almost predict them. Confusing le and lui is one of them.

The problem usually becomes clear with two very ordinary sentences:

Je le vois.
I see him.

Je lui parle.
I speak to him.

Students quite reasonably ask: if both sentences refer to “him,” why is it le in one sentence and lui in the other?

The answer is in the French verb, not in the English pronoun.

French says:

voir quelqu’un
to see someone

but:

parler à quelqu’un
to speak to someone

With voir, the person follows the verb directly:

Je vois Paul. → Je le vois.

With parler, French requires à:

Je parle à Paul. → Je lui parle.

This is the distinction I want students to notice first. Instead of asking, “How do I translate him?”, look at the construction of the French verb.

Direct objects and indirect objects

Grammatically, le is a direct-object pronoun and lui is an indirect-object pronoun.

If you have studied French grammar formally, you may know the terms COD (complément d’objet direct) and COI (complément d’objet indirect). The terminology is useful, but the underlying idea is quite simple.

A direct object follows the verb without a preposition:

Je vois Paul.
I see Paul.

J’écoute Marie.
I listen to Marie.

J’aide mon frère.
I help my brother.

When we replace those nouns with pronouns, French uses le, la, or les:

Je vois Paul. → Je le vois.

J’écoute Marie. → Je l’écoute.

J’aide mes parents. → Je les aide.

Le is masculine singular, la is feminine singular, and les is plural. They can refer to people or things:

Tu connais Sophie ? → Oui, je la connais.

Tu prends le train ? → Oui, je le prends.

With an indirect object, the person is connected to the verb through à in many of the constructions we are discussing:

Je parle à Paul.

Je téléphone à Marie.

J’écris à mes parents.

These become:

Je lui parle.

Je lui téléphone.

Je leur écris.

For one person, we use lui. For more than one person, we use leur.

One thing that surprises many beginners is that lui can mean either “to him” or “to her.”

Je lui parle.

Depending on the context, that can mean:

“I am speaking to him.”

or:

“I am speaking to her.”

Direct-object pronouns do distinguish gender:

Je le vois.
I see him.

Je la vois.
I see her.

A simple reference is:

‍ ‍ Singular Plural

Direct obejct le / la les

Indirect object lui leur

The chart helps, but knowing how the verb is constructed helps much more.

The same person can be le or lui

Take Paul.

Je vois Paul. → Je le vois.

Je connais Paul. → Je le connais.

J’attends Paul. → Je l’attends.

Now change the verb:

Je parle à Paul. → Je lui parle.

J’écris à Paul. → Je lui écris.

Je réponds à Paul. → Je lui réponds.

Paul has not changed. His relationship to the verb has.

This is why I encourage students to learn French verbs with their constructions. Instead of memorizing only:

attendre = to wait

learn:

attendre quelqu’un

Instead of only:

répondre = to answer

learn:

répondre à quelqu’un

That extra word can save you a great deal of confusion later.

English often points you in the wrong direction

This is where many perfectly logical mistakes come from.

English says “to listen to someone,” so students sometimes expect French to use à as well.

But French says:

écouter quelqu’un

Therefore:

J’écoute Paul. → Je l’écoute.

Not:

Je lui écoute.

The same problem appears with attendre.

English says “to wait for someone,” but French says:

attendre quelqu’un

So:

J’attends Marie. → Je l’attends.

And:

chercher quelqu’un
to look for someone

gives us:

Je cherche Paul. → Je le cherche.

Then French does the opposite with téléphoner.

English says:

“I call Sophie.”

But French says:

Je téléphone à Sophie.

So:

Je lui téléphone.

This is why I would not memorize le = him and lui = to him as fixed translations. It works until it doesn't.

It is much more useful to become familiar with complete patterns:

voir quelqu’un — to see someone
connaître quelqu’un — to know someone
aider quelqu’un — to help someone
écouter quelqu’un — to listen to someone
attendre quelqu’un — to wait for someone
appeler quelqu’un — to call someone

and:

parler à quelqu’un — to speak to someone
répondre à quelqu’un — to answer someone
téléphoner à quelqu’un — to call someone
écrire à quelqu’un — to write to someone

After enough repetition, you stop having to analyze every sentence from the beginning.

One rule that works — until it doesn't

Students sometimes notice the pattern and make themselves a shortcut:

no à → le

à → lui

For many common verbs, this works very well. But I always warn students not to make the rule too absolute.

Consider:

Je pense à Paul.

You cannot say:

Je lui pense.

French says:

Je pense à lui.
I’m thinking about him.

Similarly:

Je tiens beaucoup à Marie. → Je tiens beaucoup à elle.

Here French keeps the preposition and uses what is often called a stressed pronoun: lui, elle, eux, or elles.

You can see the same form after other prepositions:

Je travaille avec lui.
I work with him.

This lui looks exactly like the one in:

Je lui parle.

but it is doing a different job. In Je lui parle, it is an indirect-object pronoun placed before the verb. In Je travaille avec lui, it comes after the preposition avec.

Things are different again:

Je pense à mon travail. → J’y pense.

Here French normally uses y, not lui.

You do not need to master every use of y to understand le and lui, but it is useful to know from the beginning that not every à automatically produces lui.

When a sentence has both

Students often become nervous the first time they see a sentence such as:

Je le lui donne.

It looks like several tiny pronouns have suddenly been piled together. The easiest way to understand it is to go back to the full sentence:

Je donne le livre à Paul.
I give the book to Paul.

Le livre is the direct object.

À Paul is the indirect object.

Replace only Paul:

Je lui donne le livre.

Replace only the book:

Je le donne à Paul.

Replace both:

Je le lui donne.

So:

le = le livre

lui = à Paul

Once you see where both pronouns came from, the sentence looks much less mysterious.

The same thing happens with:

Marie montre la photo à Sophie.

Marie la montre à Sophie.

Marie lui montre la photo.

Marie la lui montre.

I would not worry about memorizing every possible pronoun combination at once. First make sure you understand what each pronoun is replacing.

Where do le and lui go?

In an ordinary sentence, both pronouns normally come before the conjugated verb:

Je le vois.

Je lui parle.

In a negative sentence:

Je ne le vois pas.

Je ne lui parle pas.

English speakers often need some time to get used to this because English puts the pronoun after the verb: “I see him.” French says literally something closer to “I him see.”

With an infinitive, the pronoun normally goes before the infinitive it belongs to:

Je vais voir Paul. → Je vais le voir.

Je vais parler à Paul. → Je vais lui parler.

The more often you hear phrases such as je vais le voir, je veux lui parler, or je peux l’aider, the more natural this word order becomes.

Commands are a little different. In an affirmative command, the pronoun comes after the verb:

Regarde-le !
Look at him!

Parle-lui !
Speak to him/her!

In a negative command, it returns to its usual position:

Ne le regarde pas !

Ne lui parle pas !

Why the distinction matters later

The difference between direct and indirect objects becomes particularly important in the passé composé.

Take Marie:

J’ai vu Marie hier.

Replace Marie with a pronoun:

Je l’ai vue hier.
I saw her yesterday.

Because l’ is a preceding direct object referring to a feminine singular person, the past participle agrees:

vue

Now compare:

J’ai parlé à Marie hier.

This becomes:

Je lui ai parlé hier.

There is no agreement with lui because it is an indirect object.

So:

Marie ? Je l’ai vue hier.

but:

Marie ? Je lui ai parlé hier.

So this isn't just one of those small beginner grammar points you learn and forget. The same distinction comes back later in French.

The mistakes make sense

A student may say:

Je lui vois

for “I see him.”

I know immediately what happened. The student understands the meaning but has chosen the pronoun based on the English sentence.

French uses:

voir quelqu’un

so it must be:

Je le vois.

Or someone may say:

Je le parle

for “I speak to him.”

But French says:

parler à quelqu’un

so we need:

Je lui parle.

I particularly like comparing écouter and téléphoner because English leads learners in opposite directions:

“I listen to him.”

Je l’écoute.

“I call him.”

Je lui téléphone.

Once you know écouter quelqu’un and téléphoner à quelqu’un, neither sentence is strange. The real challenge is getting used to the French construction instead of automatically following the English one.

Knowing the rule and using it are two different things

Many students understand direct and indirect objects quite quickly when they see them written down. Speaking is another matter.

During a conversation, you are thinking about vocabulary, pronunciation, conjugation, what the other person just said, and what you want to say next. You do not have much time to stop and analyze whether parler takes an indirect object.

That is why repetition matters more than another page of grammar explanations.

Practice complete phrases:

Je le connais.

Je l’attends.

Je l’écoute.

Je lui parle souvent.

Je lui écris demain.

Je vais le voir ce soir.

Je vais lui répondre.

Then change the tense:

Je parle à ma sœur tous les jours. → Je lui parle tous les jours.

J’ai parlé à ma sœur hier. → Je lui ai parlé hier.

Je vais parler à ma sœur demain. → Je vais lui parler demain.

Eventually parler à quelqu’un → lui parler begins to feel like one familiar unit.

When you're unsure, put the name back

This is probably the simplest trick I give students.

Suppose you want to say:

“I’m waiting for him.”

And suddenly you cannot remember whether you need le or lui.

Forget the pronoun for a moment. How would you say:

“I’m waiting for Paul”?

J’attends Paul.

Now the construction is obvious:

attendre quelqu’un

So:

Je l’attends.

Now try:

“I’m answering him.”

Put Paul back:

Je réponds à Paul.

You can immediately see:

répondre à quelqu’un

Therefore:

Je lui réponds.

Pronouns sometimes make a sentence feel more abstract than it really is. Putting a name back into the sentence often reveals the grammar you already know.

What I want students to remember

If you hesitate between le and lui, do not begin by asking which one translates the English word him.

Ask how the French verb works.

voir quelqu’un → Je le vois.

attendre quelqu’un → Je l’attends.

parler à quelqu’un → Je lui parle.

répondre à quelqu’un → Je lui réponds.

Once you start learning verbs this way, the distinction becomes much easier. Once you know how the verb works, the pronoun usually takes care of itself.

This is also the kind of grammar point that becomes easier through actual speaking practice. In French classes at Polyglottist Language Academy, students use grammar in complete sentences and conversation rather than encountering it only in charts and written exercises.

So when you are unsure, go back to the verb.

Je le vois because French says voir quelqu’un.

Je lui parle because French says parler à quelqu’un.

That is the distinction that matters.
