Impersonal Expressions in French

In Brief

French often uses a fixed il in general statements such as il faut partir (“we need to leave”), il semble que… (“it seems that…”), and il s'agit de… (“it concerns…”). This il does not mean “he.” The usual choice is between an infinitive for a general action and que + a conjugated verb when the clause has its own subject; expressions of necessity, judgment, or possibility often require the subjunctive after que.

Overview

An impersonal expression presents a fact, judgment, need, appearance, or topic without making a particular person or thing the grammatical subject. French normally places il in the subject position. In this use, il is a dummy subject (a word required by the grammar but not referring to anyone): Il est important de comprendre means “It is important to understand,” not “He is important to understand.”

English also uses impersonal “it,” so the basic idea is familiar. However, the structures do not always match word for word. English “we have to,” “you should,” or “apparently” may become il faut, il vaut mieux, or il paraît que. Learning each expression as a complete pattern is more reliable than translating “it” first.

At B1, these constructions connect familiar infinitives with the subjunctive (a verb form used when a clause is presented as necessary, desired, uncertain, or evaluated rather than simply asserted as fact). They are useful everywhere: practical instructions, recommendations, opinions, news, formal writing, and ordinary conversation.

How It Works

The impersonal il stays singular

The placeholder il remains masculine singular regardless of what follows. The adjective in patterns such as il est important also stays masculine singular.

• Il est nécessaire de réserver. — It is necessary to book.
• Il faut deux signatures. — Two signatures are required.
• Il s'agit de décisions urgentes. — These are urgent decisions / The matter concerns urgent decisions.

The plural noun décisions does not turn il s'agit into a plural expression. Similarly, do not change important to importante because the next noun or speaker is feminine.

The main families

Function	Pattern	Typical meaning	What normally follows
necessity	il faut	it is necessary; one/we/you must	noun, infinitive, or que + subjunctive
evaluation	il est + adjective	it is important, possible, clear…	de + infinitive or que + clause
recommendation	il vaut mieux	it is better; had better	infinitive or que + subjunctive
appearance	il semble	it seems	infinitive or que + clause, often subjunctive
reported information	il paraît	it appears; apparently	que + indicative
topic or issue	il s'agit de	it concerns; it is a matter of	noun, pronoun, or infinitive
sufficiency	il suffit de / que	it is enough; all you need to do	infinitive or que + subjunctive

An infinitive is the unconjugated dictionary form of a verb, such as partir (“to leave”). A clause is a group of words containing its own subject and verb, such as que tu partes (“that you leave”).

General action: infinitive

Use an infinitive when the action is general, or when the person responsible is obvious and does not need to be named.

• il faut + infinitive: Il faut vérifier le numéro.
• il est + adjective + de + infinitive: Il est utile de comparer les prix.
• il vaut mieux + infinitive: Il vaut mieux attendre demain.
• il suffit de + infinitive: Il suffit de remplir ce formulaire.

The preposition matters. After il est + adjective, French normally uses de before an infinitive: Il est difficile de choisir. After il faut and il vaut mieux, there is no de: Il faut choisir; il vaut mieux choisir.

The infinitive does not always mean that literally everyone performs the action. Context supplies the understood person:

• Le train part dans cinq minutes. Il faut courir. — The train leaves in five minutes. We need to run.
• Pour ouvrir le fichier, il suffit de cliquer ici. — To open the file, you just need to click here.

A named subject: que + verb

When the second action needs its own explicit subject, use que and a conjugated verb:

• Il faut que tu répondes. — You need to answer.
• Il vaut mieux que nous partions. — We had better leave.
• Il est possible qu'elle soit en retard. — She may be late.

After necessity, recommendation, possibility, or subjective evaluation, that verb is usually subjunctive. The subject after que may be a noun as well as a pronoun: Il faut que le directeur signe.

Do not treat every impersonal que expression as a subjunctive trigger. Expressions presenting information as likely or certain normally take the indicative (the ordinary verb form used to state facts):

Meaning	Usual construction	Example
necessity or importance	subjunctive	Il est essentiel que vous soyez prêts.
possibility or doubt	subjunctive	Il est possible qu'il pleuve.
probability	indicative	Il est probable qu'il viendra.
certainty or evidence	indicative	Il est clair qu'elle connaît la réponse.
reported appearance	indicative	Il paraît qu'ils ont déménagé.

Negative or questioning forms can make certainty less firm and therefore allow or favor the subjunctive: Il n'est pas certain qu'il vienne. At B1, first learn the common positive patterns rather than trying to derive the mood from the English translation alone.

Il semble que and il paraît que

These two expressions overlap, but their viewpoint differs.

Il semble que presents an impression or inference. The subjunctive is common when the conclusion remains tentative:

• Il semble qu'il ait raison. — It seems that he is right.
• Il semble que la situation s'améliore. — The situation seems to be improving.

The indicative is also found when the speaker treats the conclusion as more factual, especially in less careful everyday usage. The construction il me semble que often introduces the speaker's own considered opinion and commonly takes the indicative: Il me semble que vous avez déjà payé.

Il paraît que usually reports information that is circulating or comes from another source. It is normally followed by the indicative:

• Il paraît que le musée est fermé. — Apparently the museum is closed.

A useful first distinction is: il semble que = “the evidence gives this impression”; il paraît que = “this is what people say / what I have heard.”

Il s'agit de

Il s'agit de identifies the topic, the issue, or what is involved. It is always impersonal and is followed by de:

• Il s'agit d'un problème grave. — It is a serious problem / The issue is serious.
• De quoi s'agit-il ? — What is it about?
• Il ne s'agit pas de gagner, mais d'apprendre. — It is not about winning, but learning.

English “it is about” can describe the content of a book or film, but French often prefers parler de in that specific setting: Ce film parle d'une famille en crise. Use il s'agit de when identifying or clarifying the matter at hand. Never make it agree with a following plural noun, and do not use il s'agit que.

Common Mistakes

Treating impersonal il as “he”

• Wrong: Elle est nécessaire de réserver une table.
• Right: Il est nécessaire de réserver une table.
• Why: Il is a fixed placeholder here. It does not agree with table or with the person who needs to book.

Adding de after il faut

• Wrong: Il faut de partir maintenant.
• Right: Il faut partir maintenant.
• Why: Il faut takes an infinitive directly. By contrast, an adjective pattern needs de: Il est nécessaire de partir.

Using an infinitive when the second clause names a subject

• Wrong: Il faut tu téléphoner au client.
• Right: Il faut que tu téléphones au client.
• Why: Once tu is stated as the subject of the action, French needs que + a conjugated verb. After il faut que, that verb is subjunctive.

Using the indicative after a clear subjunctive trigger

• Wrong: Il est important que vous êtes à l'heure.
• Right: Il est important que vous soyez à l'heure.
• Why: The expression evaluates the situation as important, so the clause after que takes the subjunctive.

Putting every que clause in the subjunctive

• Wrong: Il paraît qu'elle soit malade.
• Right: Il paraît qu'elle est malade.
• Why: Il paraît que normally reports information and takes the indicative. Likewise, positive il est probable que and il est clair que usually take the indicative.

Translating “it is about” mechanically

• Wrong: Il s'agit que nous devons réduire les coûts.
• Right: Il s'agit de réduire les coûts. / Le problème, c'est que nous devons réduire les coûts.
• Why: Il s'agit requires de + noun or infinitive. It cannot directly introduce a que clause in this meaning.

Usage Notes

General statements can sound less direct

Impersonal wording often avoids pointing at one person. Compare:

• Tu dois refaire le formulaire. — You must redo the form.
• Il faut refaire le formulaire. — The form needs to be redone / We need to redo the form.
• Il faudrait refaire le formulaire. — The form should probably be redone.

The first directly assigns responsibility. Il faut presents the need as general, while the conditional il faudrait softens it into a suggestion. This makes impersonal expressions especially common in workplace instructions and polite advice.

Spoken and written preferences

Il faut and il vaut mieux are fully natural in speech and writing. Il paraît que is common in conversation when passing on news. Il s'agit de is frequent in explanations, presentations, journalism, and formal discussion, though it also occurs in ordinary speech in the question De quoi s'agit-il ?

Formal writing uses a wider set of adjective constructions: il est nécessaire de, il est souhaitable que, il est peu probable que. Everyday speech may choose shorter alternatives such as il faut, mieux vaut, or peut-être que.

Negation surrounds the conjugated impersonal verb

Place ne…pas around the finite verb:

• Il ne faut pas attendre. — We must not wait.
• Il ne semble pas comprendre. — He does not seem to understand. Here il may refer to a real male person, so this is a personal use of sembler.
• Il ne s'agit pas d'argent. — It is not about money.

The first and third are impersonal. The second illustrates why context matters: the form il can be either a placeholder or an ordinary pronoun meaning “he.”

Beyond the Basics / Advanced Use

Tense and modality belong to the impersonal verb

These expressions can appear in several tenses and moods:

Form	Typical meaning	Example
il faut	present necessity	Il faut agir.
il a fallu	necessity that arose in the past	Il a fallu annuler la réunion.
il fallait	ongoing or background necessity	Il fallait réserver plusieurs semaines avant.
il faudra	future necessity	Il faudra vérifier les résultats.
il faudrait	softened advice or hypothetical need	Il faudrait en discuter.
il aurait fallu	an unfulfilled past obligation	Il aurait fallu prévenir Paul.

With que, the subordinate clause still follows the mood required by the expression: Il faudra que vous confirmiez votre présence. In careful French, a completed earlier action can use the past subjunctive (the subjunctive of avoir or être plus a past participle): Il semble qu'elle ait oublié le rendez-vous.

Infinitives can carry their own time and voice

An infinitive may refer to an earlier event or use the passive:

• Il semble avoir oublié. — He seems to have forgotten. Here il refers to a person; avoir oublié is a past infinitive.
• Il est regrettable d'avoir perdu autant de temps. — It is regrettable to have lost so much time.
• Il est important d'être entendu. — It is important to be heard.

These forms preserve the same basic structure while adding time or voice.

Alternative word order and set variants

Mieux vaut + infinitive is a common compact variant of il vaut mieux + infinitive: Mieux vaut prévenir que guérir (“Prevention is better than cure,” literally “Better to prevent than to cure”). It is slightly more proverbial or concise, but not rare.

You may also see a person added with an indirect-object pronoun in formal or careful style: Il m'est difficile de répondre (“It is difficult for me to answer”), Il nous semble nécessaire de vérifier (“It seems necessary to us to check”). These pronouns identify whose judgment or experience is involved without changing the impersonal framework.

At C1 and beyond, formal French expands this family with constructions such as il convient de (“it is appropriate to”), il importe de (“it is important to”), and il ressort de… que… (“it emerges from… that…”). Their logic builds directly on the B1 patterns here, but their register and mood choices deserve separate study.

Practice Tips

1. Sort by the word after the expression. Make three columns: direct infinitive (il faut partir), de + infinitive (il est utile de partir), and que + clause (il faut que tu partes). Add new examples as complete chunks.
2. Practice one idea in two forms. Change a general statement into one with a named subject: Il vaut mieux attendre → Il vaut mieux que nous attendions. This trains both structure and subjunctive forms.
3. Listen for source and certainty. When reading news or hearing conversation, note whether French uses il semble que, il me semble que, or il paraît que. Ask whether the speaker is drawing an inference, giving an opinion, or repeating information.
