Pronoms avec Verbes Modaux + Infinitif

When a French sentence contains a modal verb (pouvoir, vouloir, devoir, savoir, falloir, aimer, préférer) or a periphrastic construction (aller + infinitive, venir de + infinitive, être en train de + infinitive) followed by an infinitive, learners face a choice with only one right answer. Does the object pronoun attach to the conjugated modal — je le veux voir — or to the infinitive — je veux le voir? Modern French is unambiguous: the pronoun attaches to the infinitive. It sits between the conjugated verb and the infinitive, glued to the infinitive that semantically governs it. Je veux le voir. Never je le veux voir.

This page drills the rule across every modal and periphrastic context, including stacked pronouns (je vais le leur dire) and past-tense modals (j'aurais voulu lui parler). It also explains why the rule is what it is — a story that involves Latin syntax, the loss of clitic climbing in French, and a striking divergence from Spanish and Italian, which kept it.

The core rule: the pronoun goes with the infinitive

A pronoun always lands in front of the verb that governs it semantically — the verb whose meaning makes the pronoun the object. With a modal + infinitive structure, the modal contributes modality (want, can, must), but the actual action — the verb that takes the object — is the infinitive. The pronoun belongs to the infinitive, and it sits there.

The shape is rigid: subject + conjugated modal + clitic pronoun(s) + infinitive. The pronoun is one slot away from the infinitive — never separated by anything else, never lifted up in front of the modal.

The principle is easy to state once you internalize it. Try the test: ask which verb the pronoun is the object of. In je veux le voir, the pronoun le is the object of voir (you see him), not of veux (you can't say je veux le meaning "I want him" — you'd say je le veux, but with a different meaning of "want," and crucially, vouloir there has a different syntactic frame). Wherever the pronoun semantically belongs, that's where it sits.

The full set of modal verbs

Modern French treats the following verbs as modals when followed by a bare infinitive — meaning the pronoun attaches to the infinitive in every case:

The same rule applies to all of them.

Periphrastic constructions: same rule

The same logic extends to periphrastic verb constructions — the futur proche with aller, the passé récent with venir de, and the progressive être en train de. In every case, the pronoun lands in front of the infinitive, not the conjugated verb.

Futur proche: aller + infinitive

Passé récent: venir de + infinitive

Progressive: être en train de + infinitive

The pattern is consistent across all three: subject + conjugated periphrastic verb (+ preposition) + pronoun + infinitive. Note that in venir de and être en train de, the de belongs to the construction itself; the pronoun follows the de and immediately precedes the infinitive.

Stacked pronouns before the infinitive

When you need two pronouns — a direct object and an indirect object, or one of these with y or en — the entire cluster sits in front of the infinitive, in the standard order: me/te/se/nous/vous → le/la/les → lui/leur → y → en.

The full cluster moves as a single unit. Je vais le leur dire — three words le leur dire form a tight phonetic group; the pronouns are inseparable from the infinitive.

In the negative, ne...pas wraps around the conjugated verb, not around the infinitive cluster:

The shape: subject + ne + conjugated modal + pas + pronoun(s) + infinitive. Notice that pas falls between the modal and the pronoun cluster — it does not fall between the pronouns and the infinitive.

Past modals: the pronoun still attaches to the infinitive

When the modal itself is in a compound tense (passé composé, conditionnel passé, plus-que-parfait), the rule does not change. The pronoun continues to attach to the infinitive — even though the modal itself has its own auxiliary now.

The shape: subject + auxiliary + (past participle of modal) + pronoun + infinitive. J'ai pu le voir — three slots: ai (auxiliary), pu (past participle of pouvoir), le voir (pronoun + infinitive). The pronoun never climbs; it stays glued to the infinitive.

In the negative compound modal, ne...pas wraps around the auxiliary + past participle of the modal:

The order is subject + ne + auxiliary + pas + past participle + pronoun(s) + infinitive. The pronouns are still down at the infinitive end of the sentence, separated from the auxiliary by the past participle of the modal.

Why French does this — and why Spanish doesn't

This rule has a story. Old French (twelfth–fourteenth centuries) actually allowed clitic climbing — the pronoun could lift up in front of the modal, just like in modern Spanish: je le veux faire was a valid Old French sentence, structurally parallel to Spanish lo quiero hacer. From the seventeenth century onward, French gradually phased this out. The modern grammarians cemented the rule: in standard French, the clitic stays with the infinitive that governs it.

Spanish, Italian, and Portuguese kept clitic climbing as an option. Spanish still allows both quiero verlo (clitic on the infinitive) and lo quiero ver (climbed). Italian works the same way: voglio vederlo / lo voglio vedere. French chose one structure and enforced it strictly.

The result is that French is unusual among Romance languages in not allowing clitic climbing. If you've studied Spanish, you must override the lo quiero ver instinct. The French equivalent is always je veux le voir, never je le veux voir.

The reason for the strictness is partly historical (the seventeenth-century grammarians were prescriptive about clitic position) and partly structural: French clitics are extraordinarily tightly bound to their verb, and once the system collapsed climbing as an option, the rule became a hard syntactic constraint rather than a stylistic preference.

Imperative mood with modal + infinitive

When the modal itself is in the imperative, the affirmative imperative rule applies to the modal — the pronoun follows it with a hyphen. But this is rare in modern French, and most learners encounter it only in fixed expressions or formal commands.

In ordinary speech, you'd phrase this differently — contactez-le, apprends à le faire — sidestepping the modal-imperative entirely.

Side-by-side comparison: pronoun positions across constructions

To anchor the rule, here's a single object — le voir (to see him) — across the major constructions:

In every row from "Modal: vouloir" downward, the pronoun le sits in front of voir — never in front of the conjugated verb. The pattern is rigorously consistent.

The faire-causative exception (preview)

There is one structurally similar construction where the rule does invert: faire + infinitive in the causative sense (je le fais réparer — "I have it repaired"). In that construction, the pronoun attaches to faire, not to the infinitive — je le fais réparer, never je fais le réparer. The reason is that in the causative, faire and the infinitive form a single semantic predicate, and the pronoun attaches to the conjugated verb of that complex.

This is treated in detail on the verbs/causative/faire-causative page. For now, just know: modal + infinitive — pronoun on the infinitive. Faire causative — pronoun on faire. The two structures look similar but follow opposite rules.

Common Mistakes

Mistake 1: Putting the pronoun before the modal (clitic climbing — Spanish-influenced).

This is the single most common error among Spanish-speaking learners and among English speakers who have studied Spanish first. The Spanish lo quiero ver pattern simply does not exist in modern French.

Mistake 2: Putting the pronoun after the conjugated verb in English style.

English speakers default to post-verbal placement because that's where English puts its objects. French requires the pronoun to be pre-infinitive.

Mistake 3: Forgetting that the pronoun stays with the infinitive in compound past modals.

The compound auxiliary belongs to the modal (pu is the past participle of pouvoir), not to the infinitive voir. The pronoun belongs to voir and stays there.

Mistake 4: Stacking pronouns in front of the modal.

The full pronoun cluster — including stacked direct + indirect objects — moves as a unit and lands in front of the infinitive.

Mistake 5: Misplacing ne...pas with stacked pronouns and infinitive.

The negation always wraps the conjugated verb. The pronoun + infinitive cluster sits after pas, undisturbed.

Mistake 6: Confusing modal + infinitive with faire causative.

The causative faire is a structural exception to the rule on this page. With faire + infinitive in the causative sense, the pronoun is in front of faire. With every other modal, it's in front of the infinitive.

Key Takeaways

• The pronoun attaches to the infinitive, not the modal. This is the rigid rule of modern French. Je veux le voir.
• All major modals follow this rule: pouvoir, vouloir, devoir, savoir, falloir, aimer, préférer, oser, espérer, compter.
• Periphrastic constructions follow it too: aller
  • infinitive (je vais lui parler), venir de
    • infinitive (je viens de le voir), être en train de
      • infinitive (je suis en train de le faire).
• Stacked pronouns all sit in front of the infinitive in their normal cluster order: je vais le leur dire, tu peux me le donner.
• Compound past modals keep the rule intact: j'ai pu le voir, j'aurais voulu lui parler. The auxiliary belongs to the modal, the pronoun to the infinitive.
• No clitic climbing. Unlike Spanish (lo quiero ver) or Italian (lo voglio vedere), French does not allow the pronoun to lift up to the conjugated verb.
• The faire causative is the exception — there, the pronoun attaches to faire. Treat it as a separate construction.

The rule is simple in principle and unforgiving in practice. Drill it across all the modals and all the past tenses until the pronoun-on-the-infinitive position is your reflex.
