French Passive Voice: How It Works and When to Actually Use It
A clear guide to forming and using the French passive voice, including when to swap it for 'on' or a reflexive verb instead.
The French passive voice lets you shift focus from who does something to what gets done. The French passive voice follows a simple formula, but many learners avoid it because they're not sure when it sounds natural versus when active voice or the pronoun 'on' works better. This guide breaks down the structure, the tenses, and the real usage rules.
What the French Passive Voice Actually Is
In an active sentence, the subject does the action. In a passive sentence, the subject receives the action. Compare these two:
| Type | French | English |
|---|---|---|
| Active | Le chef prépare le repas. | The chef prepares the meal. |
| Passive | Le repas est préparé par le chef. | The meal is prepared by the chef. |
The object of the active sentence becomes the subject of the passive sentence. The original subject (the chef) can still appear, introduced by 'par' (by). It can also be dropped entirely if it's unknown or unimportant.
How to Form the French Passive Voice
The structure is: subject + être (conjugated) + past participle. The past participle must agree in gender and number with the subject, just like a regular adjective.
| Tense | Formula | Example |
|---|---|---|
| Present | est/sont + past participle | La lettre est envoyée. (The letter is sent.) |
| Passé composé | a été/ont été + past participle | La lettre a été envoyée. (The letter was sent.) |
| Imparfait | était/étaient + past participle | La lettre était envoyée chaque mois. (The letter was sent each month.) |
| Futur simple | sera/seront + past participle | La lettre sera envoyée demain. (The letter will be sent tomorrow.) |
| Conditionnel | serait/seraient + past participle | La lettre serait envoyée si... (The letter would be sent if...) |
| Subjonctif | soit/soient + past participle | Il faut que la lettre soit envoyée. (The letter must be sent.) |
Notice that the passive voice in passé composé uses 'a été', not just 'est'. This trips up a lot of learners. 'La maison est construite' means the house is (currently) built, as a state. 'La maison a été construite' means the house was built, as a completed action.
Agreement Rules for the Past Participle
The past participle agrees with the grammatical subject of the passive sentence. That subject is the thing receiving the action, so its gender and number drive the agreement.
- Masculine singular: Le document est signé.
- Feminine singular: La lettre est signée.
- Masculine plural: Les documents sont signés.
- Feminine plural: Les lettres sont signées.
This is the same agreement logic you use for adjectives. If you've already worked through French grammar at the A1-B2 levels, you've seen this pattern before with adjectives modifying nouns.
Par vs De: Which Preposition Introduces the Agent?
Most of the time, you use 'par' to introduce who did the action. 'De' is used in a smaller set of fixed expressions, mostly involving states or emotions rather than deliberate actions.
| Preposition | When to use it | Example |
|---|---|---|
| par | Physical actions, most verbs | Le gâteau a été mangé par les enfants. |
| de | States, emotions, verbs like aimer, entourer, couvrir | Elle est entourée d'amis. / Il est aimé de tous. |
In practice, 'par' covers the vast majority of passive sentences you will write or read.
When to Use 'On' or a Reflexive Verb Instead
French speakers often avoid the passive voice in everyday speech. It can sound formal or even clunky in conversation. Two alternatives are more common in spoken French.
First, use 'on' as an impersonal subject. Instead of 'Le français est parlé ici', most French speakers say 'On parle français ici'. It's shorter, more natural, and very common.
Second, use a pronominal (reflexive) verb. Some verbs have a reflexive form that carries a passive meaning. 'Ce mot ne s'utilise plus' means 'This word is no longer used', without needing être at all.
| Register | Preferred structure | Example |
|---|---|---|
| Written/formal | Passive with être | La réunion est annulée par le directeur. |
| Spoken/informal | On + active verb | On a annulé la réunion. |
| Idiomatic | Reflexive verb | Ça se fait pas. (That's not done.) |
Common Mistakes Learners Make
- Forgetting to agree the past participle with the subject.
- Confusing 'est préparé' (present state) with 'a été préparé' (completed action).
- Using the passive when 'on' or a reflexive verb sounds more natural.
- Using 'par' when 'de' is the idiomatic choice (especially with emotions).
- Applying passive voice to verbs that only work with être in compound tenses (aller, venir, etc.), which creates double-être constructions that need careful handling.
Passive Voice in TCF and TEF Writing Tasks
If you're preparing for a French language exam for immigration, the passive voice matters. Written production tasks at B1 and above reward grammatical range. Using the passive correctly, especially across multiple tenses, signals control of the language. Overusing it in spoken tasks (like the oral section) can sound unnatural, so know when to switch to 'on'.

FAQ
Is the passive voice common in spoken French?
Less common than in English. French speakers usually prefer 'on' or a reflexive verb in conversation. The passive voice appears more in formal writing, news articles, official documents, and academic texts.
How do I know whether to use 'par' or 'de' in a passive sentence?
Use 'par' for deliberate actions: someone physically or intentionally doing something. Use 'de' for states, emotions, or habitual conditions, especially with verbs like aimer, respecter, entourer, and couvrir. When in doubt, 'par' is almost always acceptable.
Can all French verbs be made passive?
Only transitive verbs, meaning verbs that take a direct object, can form a true passive. Intransitive verbs (like partir or aller) cannot. Some transitive verbs that use indirect objects (like parler à, téléphoner à) also cannot form a standard passive in French, unlike in English.
What is the difference between 'est préparé' and 'a été préparé'?
'Est préparé' describes a current state: the meal is (already) prepared. 'A été préparé' describes a completed action in the past: the meal was prepared (at some point). The distinction matters, and mixing them up is a common mistake at B1 and B2 level.
