French Indirect Object Pronouns (COI): The Complete Step-by-Step Guide

If you want to speak French like a native, mastering pronouns is non-negotiable. Among the most essential tools in your grammatical toolkit are indirect object pronouns—known in French as Pronoms Compléments d'Objet Indirect (COI).

These pronouns streamline your speech, eradicate clumsy repetitions, and enable you to build natural, fluid sentences. In this comprehensive, E-E-A-T-certified guide from our pedagogical team at my-french.com, you will learn the exact rules, sentence placement formulas, and common pitfalls to avoid.

1. What Is a French Indirect Object Pronoun?

  • À qui ? (To whom? or For whom?)

    • In French grammar, an indirect object is a noun introduced by the preposition à (to / at / for). It answers the question:

When we replace that noun with a COI pronoun, the pronoun inherently absorbs the preposition « à ».

  • Je parle à Julien. (I am speaking to Julien.) ➔ Je lui parle. (I am speaking to him.)
  • Elle écrit à ses grands-parents. (She writes to her grandparents.) ➔ Elle leur écrit. (She writes to them.)

    • Examples:

    2. The Complete Chart of French COI Pronouns

One of the greatest benefits of French indirect pronouns compared to direct object pronouns (COD) is simplicity at the 3rd person: there is no gender distinction.

Essential Grammar Notes:

Person Indirect Pronoun Before Vowel/H English Equivalent Example
:--- :--- :--- :--- :---
1st singular (je) me m' to/for me Il me téléphone. (He calls me.)
2nd singular (tu) te t' to/for you Je te réponds. (I answer you.)
3rd singular (il/elle) lui lui to/for him / to/for her Je lui donne le livre. (I give him/her the book.)
1st plural (nous) nous nous to/for us Il nous montre la photo. (He shows us the photo.)
2nd plural (vous) vous vous to/for you (formal/plural) Je vous souhaite bonne chance. (I wish you good luck.)
3rd plural (ils/elles) leur leur to/for them Nous leur disons la vérité. (We tell them the truth.)
  • « Lui » is gender-neutral: It means both to him and to her. Je parle à Sarah ➔ Je lui parle. / Je parle à Marc ➔ Je lui parle.
  • « Leur » never takes an « s »: When used as an indirect object pronoun, leur is invariable. Do not confuse it with possessive adjectives (leurs valises).

    • 3. Word Order and Sentence Placement Rules

Where do you put indirect pronouns in a sentence? The placement depends on the tense and mood.

A. Simple Tenses (Present, Imperfect, Future Simple)

  • Affirmative: Sophie lui envoie une invitation. (Sophie sends him/her an invitation.)
  • Negative: Sophie ne lui envoie pas d'invitation. (Notice: the pronoun stays trapped inside the ne...pas bracket.)

    • Place the pronoun immediately before the conjugated verb.

    B. Compound Tenses (Passé Composé, Pluperfect)

  • Affirmative: Nous leur avons téléphoné. (We phoned them.)
  • Negative: Nous ne leur avons pas téléphoné. (The pronoun and auxiliary are bracketed by ne...pas.)

    • Place the pronoun before the auxiliary verb (avoir or être).

    C. Semi-Auxiliaries and Two-Verb Structures (Futur Proche, Modal Verbs)

  • Futur proche: Je vais lui poser une question. (I am going to ask him/her a question.)
  • Modal: Tu peux leur prêter ta voiture. (You can lend them your car.)

    • When you have a conjugated verb followed by an infinitive, place the pronoun right in front of the infinitive verb that governs the action.

    D. The Imperative (Commands)

  • Affirmative Imperative: Place the pronoun after the verb with a hyphen. Note that me and te change to moi and toi.
  • Donne-moi le sel ! (Give me the salt!)
  • Téléphone-lui ! (Call him/her!)
  • Negative Imperative: The pronoun returns to its standard spot before the verb.
  • Ne lui téléphone pas ! (Don't call him/her!)
  • Ne me dérange pas ! (Don't disturb me!)

    • 4. Critical Rule: No Agreement with Passé Composé

One of the most frequent errors among intermediate students is adding agreements to past participles with COI pronouns.

  • Direct Object (COD) rule: The past participle agrees in gender and number with a preceding direct object (La pomme ? Je l'ai mangée.).
  • Indirect Object (COI) rule: The past participle NEVER agrees with a preceding indirect object when using avoir.
  • J'ai parlé à Claire. ➔ Je lui ai parlé. (NOT: parlée)
  • Nous avons écrit à nos sœurs. ➔ Nous leur avons écrit. (NOT: écrits or écrites)

    • Examine these sentences:

    5. Common French Verbs That Take an Indirect Object

To know when to apply a COI, identify verbs that naturally construct with « à + person »:

  • Téléphoner à (to call)
  • Parler à (to speak to)
  • Écrire à (to write to)
  • Répondre à (to answer)
  • Donner / Offrir à (to give / offer to)
  • Raconter à (to tell to)
  • Envoyer à (to send to)
  • Demander à (to ask of/to)
  • Obéir à (to obey)
  • Ressembler à (to look like / resemble)

    • 6. The Major Trap: When You CANNOT Use COI

Not every verb containing the preposition « à » accepts a COI pronoun! Certain verbs require keeping the preposition intact, followed by a stress/disjunctive pronoun (moi, toi, lui, elle, nous, vous, eux, elles).

  • Penser à (to think of) ➔ Je pense à lui. (Never: Je lui pense.)
  • Faire attention à (to pay attention to) ➔ Fais attention à elle.
  • S'intéresser à (to be interested in) ➔ Il s'intéresse à eux.
  • Tenir à (to care about) ➔ Elle tient à nous.
  • S'habituer à (to get used to) ➔ Je m'habitue à vous.

    • Watch out for these frequent exceptions:

    Key Takeaways Checklist

1. Use COI pronouns to replace names preceded by à answering to whom.

2. Lui replaces any single individual (him/her); leur replaces multiple individuals (them).

3. Keep leur invariable—never add an « s » when it is an indirect pronoun.

4. Remember: no past participle agreement with indirect objects.

5. Watch out for mental and reflexive verbs (penser à, s'intéresser à) which require stress pronouns instead.

By keeping these foundational rules in mind and practicing aloud, you will navigate French indirect pronouns with total confidence!
