The little word il is one of the hardest-working pronouns in the French language. Sometimes it points to a real person — Pierre? Il est en retard. Sometimes it points to a real thing — Le livre? Il est sur la table. And sometimes it points to absolutely nothing at all — Il pleut. That last il is a grammatical placeholder, not a referent. French syntax demands a subject, so the language inserts a dummy il the way English inserts it in It is raining. Telling these uses apart is the foundation of French sentence-level grammar, and it explains why beginners often write structures that look right but sound bizarre to native ears.
This page works through both uses, gives you a reliable test for distinguishing them, and lays out the most common impersonal constructions you'll meet in everyday French.
Personal il: pointing to something real
When il is personal, it has a clear antecedent — a masculine noun that has already been mentioned, or a masculine person/thing that's contextually obvious. It works exactly the way English he or it works for masculine entities.
Pierre est arrivé à dix heures. Il avait l'air épuisé.
Pierre arrived at ten. He looked exhausted.
Tu cherches le journal ? Il est sur la table de la cuisine.
Are you looking for the newspaper? It's on the kitchen table.
Mon frère a déménagé à Marseille. Il y travaille depuis janvier.
My brother moved to Marseille. He's been working there since January.
The key feature: there's always a referent you can point to. In the first example, il = Pierre. In the second, il = le journal. In the third, il = mon frère. If someone asks "who?" or "what?", you can answer.
Note that French has no neuter pronoun the way English distinguishes he from it. The grammatical gender of the noun decides which pronoun replaces it. Le livre (masculine) takes il, la table (feminine) takes elle, even though English would call both it.
J'adore ce film. Il est sorti l'année dernière.
I love this movie. It came out last year.
La voiture est garée dehors. Elle est rouge.
The car is parked outside. It's red.
This is why translating English it requires a tiny mental check first: what's the gender of the French noun I'm replacing?
Impersonal il: a placeholder with no referent
The impersonal il is a syntactic dummy — a grammatical scaffolding that has no real-world referent. French verbs require a subject, so when the verb itself doesn't have one, the language inserts il to fill the slot. English does the same thing with it: it's raining, it's three o'clock, it's necessary that…. Nobody asks "what is raining?" because the it doesn't refer to anything.
Impersonal il always appears with a fixed set of impersonal verbs and constructions. These are not freely productive — they are memorized templates.
Weather expressions
Most weather verbs and expressions take impersonal il.
Il pleut depuis ce matin et ça me déprime.
It's been raining since this morning and it's getting me down.
Il neige beaucoup dans les Alpes en ce moment.
It's snowing a lot in the Alps right now.
Il fait un froid de canard, mets ton manteau.
It's freezing cold — put your coat on.
Il y a du brouillard sur l'autoroute, sois prudent.
There's fog on the motorway, be careful.
The verb faire deserves special attention here. With weather, it's always impersonal: il fait beau, il fait chaud, il fait nuit. You cannot personalize this — le temps fait beau is wrong. The dummy il is mandatory.
Time and dates
Telling time uses impersonal il est + the hour.
Il est presque huit heures, on devrait y aller.
It's almost eight o'clock, we should get going.
Quelle heure est-il ? — Il est neuf heures et quart.
What time is it? — It's a quarter past nine.
Il est tard, je vais me coucher.
It's late, I'm going to bed.
This il has no referent. It is purely structural. Learners sometimes try c'est huit heures, which is wrong — telling the clock time uses il, not ce.
Il y a: there is, there are
The construction il y a (literally "it has there") is one of the most common impersonal expressions in French. It corresponds to English there is / there are, and unlike English, the form does not change for plural — it's il y a whether the noun is singular or plural.
Il y a une boulangerie au coin de la rue.
There's a bakery on the corner.
Il y a trois étudiants qui n'ont pas rendu leur devoir.
There are three students who haven't handed in their homework.
Il y a quelque chose qui cloche, mais je n'arrive pas à dire quoi.
Something's off, but I can't put my finger on what.
The il here is again a pure placeholder. Y a-t-il…? is the inverted question form, and in casual spoken French you'll often hear it shortened to y a (y a quelqu'un ? = "is anyone there?").
Il faut: it is necessary
Il faut comes from the impersonal verb falloir. It's used for necessity, obligation, and what one needs to do. There is no personal version of falloir — it only exists in impersonal form.
Il faut absolument que tu lises ce livre.
You absolutely have to read this book.
Il faut deux œufs et un peu de farine pour cette recette.
You need two eggs and a bit of flour for this recipe.
Il a fallu trois heures pour réparer la voiture.
It took three hours to fix the car.
Note that il faut que + clause triggers the subjunctive in the following verb (il faut que tu lises, not que tu lis). This is one of the most common subjunctive triggers in the language.
Il s'agit de: it's about
The impersonal expression il s'agit de means "it's about" or "it concerns" — used to summarize what something is about, especially books, films, situations, or topics under discussion.
Dans ce roman, il s'agit d'une famille qui émigre au Canada.
This novel is about a family that emigrates to Canada.
Il ne s'agit pas d'argent — c'est une question de principe.
This isn't about money — it's a question of principle.
A trap: il s'agit de is always impersonal, so you cannot say ce roman s'agit de… That construction is a frequent learner error. The subject must be the dummy il, and the topic comes after de.
Il vaut mieux: it's better
Il vaut mieux (literally "it is worth more") expresses preference or recommendation. Like il faut, when followed by que + clause, it triggers the subjunctive.
Il vaut mieux partir tôt pour éviter les embouteillages.
It's better to leave early to avoid traffic.
Il vaut mieux que tu lui dises la vérité maintenant.
It's better that you tell him the truth now.
Il convient de: it is fitting / appropriate
Slightly more formal, il convient de signals what is appropriate or fitting in a given situation. You'll meet it in written French, official communication, and polite formal speech.
Il convient de remercier nos partenaires pour leur soutien.
It is fitting to thank our partners for their support.
Il conviendrait de revoir cette décision à la lumière des nouveaux faits.
It would be appropriate to reconsider this decision in light of the new facts.
In everyday speech, you'd more likely hear il faudrait or on devrait — il convient de belongs to the register of editorials, board meetings, and official letters.
Other impersonal constructions
A few more high-frequency templates worth memorizing:
Il est important de bien dormir avant un examen.
It's important to get a good night's sleep before an exam.
Il paraît qu'ils vont se marier en juin.
Apparently they're getting married in June.
Il semble que la situation s'aggrave.
It seems the situation is getting worse.
Il manque deux assiettes pour le dîner.
We're short two plates for dinner.
Il reste encore du gâteau si tu en veux.
There's still some cake left if you want some.
In il reste and il manque, notice that the noun (du gâteau, deux assiettes) is the logical subject even though il is the grammatical subject. The verb stays in the third-person singular regardless of whether the logical subject is plural.
How to tell them apart: three reliable tests
Distinguishing personal from impersonal il takes only seconds once you've internalized these tests.
Test 1: Can you replace il with a noun? If yes, it's personal. Il est arrivé → Pierre est arrivé. Personal. Il pleut → ?? pleut. Impossible — there's nothing that "rains." Impersonal.
Test 2: Is the verb impersonal-only? Verbs like falloir, pleuvoir, neiger, s'agir exist only in impersonal form. If the verb is one of these, il is automatically impersonal. There is no je faux or tu pleus.
Test 3: Does the sentence have any real-world referent? Il est important que — what is important? The clause that follows. There's no "thing" being talked about. Impersonal. Il est important pour mon père — this could be either. If il refers to a previously mentioned masculine thing ("the project"), personal. If not, it's an evaluation ("it is important for my father…"). Context decides.
Why this matters: c'est vs il est
The distinction matters because once you know which il you're dealing with, you can navigate the c'est vs il est split correctly. For evaluative impersonal statements ("it's interesting", "it's true", "it's a shame"), modern French strongly prefers c'est over il est: c'est intéressant, not il est intéressant. But il est dominates in fixed impersonal templates: il est trois heures, il est important que, il est temps de. The two systems overlap in a way that confuses learners — and the next page in this series untangles them in detail.
Comparison with English
English uses it for both personal-inanimate references and impersonal placeholders, so this distinction feels natural to English speakers in concept — but the French version has an extra wrinkle. Where English uses it freely, French has to choose between il (masculine), elle (feminine), or ce depending on what's being referenced. It's a beautiful day is c'est une belle journée, not il est une belle journée — even though English would suggest il by analogy with it.
The mismatch is easy to summarize:
| English | French | Type |
|---|---|---|
| It's raining. | Il pleut. | Impersonal — fixed |
| It's three o'clock. | Il est trois heures. | Impersonal — fixed |
| It's a book. | C'est un livre. | Identification — c'est |
| It's interesting. | C'est intéressant. | Abstract evaluation — c'est |
| It's important to read. | Il est important de lire. | Impersonal evaluation — il est |
| It (the book) is on the table. | Il est sur la table. | Personal — refers to le livre |
Common Mistakes
❌ Ce roman s'agit d'une histoire d'amour.
Incorrect — il s'agit de is impersonal-only; the topic noun cannot be the grammatical subject.
✅ Dans ce roman, il s'agit d'une histoire d'amour.
This novel is about a love story.
❌ C'est huit heures et demie.
Incorrect — clock time uses impersonal il, not c'est.
✅ Il est huit heures et demie.
It's half past eight.
❌ Le temps fait beau aujourd'hui.
Incorrect — weather expressions are always impersonal; the subject must be il, not le temps.
✅ Il fait beau aujourd'hui.
It's nice out today.
❌ Il est intéressant, ce livre.
Incorrect for general abstract evaluation — but acceptable if il refers back to a specific masculine antecedent already established in context.
✅ C'est intéressant, ce livre.
It's interesting, this book.
❌ Il y ont trois personnes dans la salle.
Incorrect — il y a never agrees in number; it stays singular even with plural objects.
✅ Il y a trois personnes dans la salle.
There are three people in the room.
Key Takeaways
- Personal il has a masculine antecedent you can name. It's interchangeable with the noun it replaces.
- Impersonal il is a syntactic placeholder. It appears with weather verbs, time expressions, il y a, il faut, il s'agit de, il vaut mieux, and a small set of evaluative templates.
- For abstract evaluations in everyday speech (it's interesting, it's nice), prefer c'est over il est.
- Il y a never agrees in number, and il s'agit de is always impersonal — these are the two most common impersonal-related errors.
- The three-test check (substitution, impersonal-only verb, no referent) resolves any ambiguity within seconds.
