Hey there, French language explorer! Ready to level up your speaking game? This chapter is your secret weapon for sounding super natural when you talk about things that have happened. We're diving into the fascinating world of French past participles when they team up with another action verb (an infinitive). You know how sometimes past participles change their endings? Well, it gets a little tricky when there’s an infinitive right after it. But don't you worry! We'll discover exactly WHEN they need to agree (like entendu chanter – *heard singing*) and, just as importantly, WHEN they absolutely don't (like with fait or laisser followed by an infinitive, where they're super stubborn and never change!). We’ll also peek into those tricky cases where the infinitive is implied, giving you full control over verbs like pu, voulu, and «dû.» Imagine you're chatting with a friend about a movie you *saw them running* in, or explaining that you *made someone laugh*. You'll learn the precise rules that make your sentences grammatically perfect, whether you're describing what you *heard a bird sing* or explaining how you *let the situation unfold*. By the end of this chapter, you won't just *know* these rules; you'll *feel* them! You'll be able to confidently construct complex sentences using past participles and infinitives, avoiding common beginner mistakes, and making your French sound incredibly fluent and natural. Let's make those verbs sing!

Overview

Welcome to this essential French grammar guide! Understanding verbs followed by infinitives is a crucial step in mastering the language, especially at the A1 level. Infinitives, the base form of a verb (like to sing or to eat), often follow other verbs in French, creating a variety of sentence structures.
This chapter will demystify these constructions, showing you how to express actions that are perceived, caused, or allowed. We’ll explore how sometimes the past participle of the main verb needs to agree with something, and sometimes it doesn't. Don't worry if this sounds a little complex at first; we'll break it down with clear examples and practical tips to ensure you can use these structures confidently.
This chapter focuses on specific scenarios where an infinitive directly follows another verb. We'll look at situations involving perception verbs (like *voir* - to see, *entendre* - to hear) and how they interact with past participles, particularly when the subject of the main verb is also the one performing the action of the infinitive. You'll learn about the subtle but important rules of agreement, or lack thereof, in these cases.
We will also cover common verbs that often appear with infinitives, such as *faire* (to make/do) and *laisser* (to let), and how their usage can change the meaning of a sentence. By the end of this guide, you'll be equipped to understand and use these common verb-infinitive combinations, making your French more natural and fluent.

How This Grammar Works

In French, when one verb is followed by another verb that expresses the action being perceived, caused, or allowed, the second verb is usually in its infinitive form. For example,
I see him run
becomes
Je le vois courir.
Here, *vois* is the main verb, and *courir* is the infinitive describing what the subject (*le* - him) is doing. This is a fundamental structure that allows for more complex sentence building.
A key point of confusion for learners is past participle agreement when these infinitive constructions are used in compound tenses (like the passé composé). We will explore how the past participle of the *first* verb (the auxiliary verb) agrees with the direct object if the direct object is placed before the verb, but only under specific conditions related to the infinitive. For instance, if you saw girls running, the past participle of *voir* would agree with girls. We will also clarify when no agreement is necessary, particularly when the direct object is actually the object of the infinitive itself.
Understanding these nuances will greatly improve the accuracy of your written and spoken French.
French Past Participle Agreement with Infinitives (entendu chanter)
When a verb of perception (like *voir*, *entendre*, *écouter*, *regarder*) is used in a compound tense (e.g., passé composé) and is followed by an infinitive, the past participle of the perception verb agrees with the direct object (COD) *if* that direct object is placed before the verb. This means if the person or thing being perceived is mentioned before the verb, you need to adjust the ending of the past participle.
Consider the case of hearing someone sing. If you heard a woman sing, and the direct object her (la) comes before the verb *entendre*, the past participle *entendu* will agree with *la* (feminine singular). So, instead of "J'ai entendu chanter, it becomes Je l'ai entendue chanter." The extra 'e' on *entendue* shows agreement with *l'* (referring to *la femme*).
French Past Participle Agreement with Infinitive (vus courir vs. vu construire)
This rule applies when the direct object (COD) is performing the action of the infinitive. If you saw someone running, and someone (le/la) is before the verb *voir*, the past participle *vu* agrees with that object. For example, if you saw a boy running, "Je l'ai vu courir.
If you saw a girl running,
Je l'ai vue courir." The agreement happens because *l'* refers to the boy or girl who is doing the running.
However, if the infinitive is a transitive verb (one that takes its own direct object), and that object is placed *after* the infinitive, then there is no agreement with the direct object of the main verb. For example, if you saw a house being built, the infinitive is *construire*. The direct object of *construire* is the house (*la maison*).
If you say "Je l'ai vu construire," *vu* does not agree with *l'* (the house) because the house is the object of *construire*, not *voir*. The construction is being done *to* the house.
Past Participle with Implied Infinitive (pu, voulu, dû)
Certain verbs, particularly *pouvoir* (to be able to), *vouloir* (to want), and *devoir* (to have to/must), have past participles (*pu*, *voulu*, *dû*) that sometimes appear without an explicit infinitive following them. In these cases, the past participle often agrees with the direct object if it precedes the verb. This happens when the object is the thing that was able to be, wanted, or had to be done.
For example, if someone asked for two books and you only had one, you might say, "Je n'ai pu en prendre qu'un." Here, *pu* doesn't agree because *en* is an indirect object. However, if you had wanted to eat some apples, and you only ate one, you could say, "Je n'ai voulu en manger qu'une." The past participle *voulu* agrees with *une* (the apple) because *une* is the direct object of the implied infinitive *manger*.
The 'Unchangeable' Fait (Faire + Infinitive)
The verb *faire* followed by an infinitive is a very common construction in French, often translating to
to make someone do something
or
to have something done.
When *faire* is used in this way, its past participle (*fait*) generally does not agree with the direct object, even if that object is placed before the verb. This is because the object is considered to be the recipient of the action of the infinitive, not the direct object of *faire* itself in the same way as with perception verbs.
For instance, if you made your children clean their room, you would say, "J'ai fait nettoyer leur chambre à mes enfants.
Even if you wanted to say
I made them clean their room" (*Je les ai fait nettoyer leur chambre*), the past participle *fait* remains invariable. The children are the indirect object of *faire* in this construction, and the direct object of *nettoyer*.
Letting Things Happen: The Verb 'Laisser' with Infinitives
Similar to *faire*, the verb *laisser* (to let, to allow) followed by an infinitive generally does not agree in its past participle (*laissé*) with a preceding direct object. The direct object is considered to be the one being allowed to do something, or the thing being allowed to happen.
For example, if you let your dog go outside, you would say, "J'ai laissé sortir mon chien.
If you wanted to say
I let them go, you would say, Je les ai laissés sortir." Ah, wait! Here is an exception to the general rule. *Laisser* *can* agree when the direct object is a person or thing that is being allowed to *do* something.
So, in
Je les ai laissés sortir,
the *e* on *laissés* agrees with *les* because *les* are the ones doing the *sortir*. This is a nuance to remember.
No Agreement: When the Object Belongs to the Infinitive (Pas d'accord : COD objet de l'infinitif)
This rule reinforces a point made earlier. When the direct object (COD) of the main verb is actually the direct object of the infinitive that follows, the past participle of the main verb does not agree with that object. The object is owned by the infinitive's action.
Think about seeing a book being read. If you saw a book being read, you would say, "J'ai vu lire le livre." Here, *vu* does not agree with *le livre* because *le livre* is the object of *lire*, not *voir*. The action of reading is performed *on* the book.
If you say, "Je l'ai vu lire," where *l'* refers to the book, *vu* still does not agree because the book is the object of *lire*.

Common Mistakes

  1. 1Wrong: "J'ai vu les filles courues."
Correct: "J'ai vu les filles courir."
*Explanation:* The infinitive *courir* should be used here, not the past participle. Agreement only happens with perception verbs in compound tenses when the infinitive is also a past participle, which is not the case here.
  1. 1Wrong:
    Je les ai fait manger.
Correct:
Je les ai fait manger.
*Explanation:* The past participle *fait* is invariable when *faire* is followed by an infinitive, even if the direct object *les* is placed before the verb.

Quick FAQ

Q

When does the past participle agree with the direct object when an infinitive follows?

The past participle of the main verb (like *voir*, *entendre*) agrees with the direct object if that object is placed before the verb AND is the one performing the action of the infinitive.

Q

Is there ever agreement with *faire* + infinitive?

Generally, no. The past participle *fait* is invariable in this construction.

Cultural Context

In French culture, the precise use of verb agreement is highly valued. Mastering these rules, even the seemingly complex ones involving infinitives, demonstrates a strong command of the language and a respect for its grammatical structure. It allows for clearer and more nuanced communication, which is appreciated in all forms of interaction.

Preguntas frecuentes (6)

Porque la canción no es la que canta; está siendo cantada. No se necesita acuerdo. Por ejemplo: "La chanson que j'ai entendu chanter".
Aquí, los cantantes SÍ son los que cantan, así que acordamos con 'entendus'. Por ejemplo: "Les chanteurs que j'ai entendus chanter".
Busca claridad. El francés quiere diferenciar quién hace la acción y a quién se le hace. Es como un GPS gramatical. Por ejemplo: "La fille que j'ai vue danser (ella baila) vs. La chanson que j'ai entendu chanter" (la canción no canta).
No realmente. En español decimos 'Las chicas que vi bailar' y 'La casa que vi construir'. No cambiamos el verbo por género o número del sujeto.
Significa que el participio pasado no cambia su final. No lleva 'e' para femenino ni 's' para plural. Se queda en masculino singular. Por ejemplo: "J'ai fait les efforts que j'ai pu."
Sí, porque 'vouloir' es un verbo modal que casi siempre implica una segunda acción (como 'hacer' o 'ir'). Por eso, no concuerda. Por ejemplo: "Elle a pris les vacances qu'elle a voulu."
