You're at a café. You want to say "there's a problem with my order." Or "it's delicious." Or "it's 8 PM." Three different English sentences, three different French structures, and they all collapse to "it is / there is" in your head.
Welcome to one of the most-googled questions in beginner French: il y a vs il est vs c'est.
Good news: there's a clean rule for each. Once you internalize them, you'll never hesitate again.
Il y a, "there is / there are"
Use it for existence. Something exists somewhere, or there's a quantity of something. Equivalent to English "there is / there are" or Spanish hay.
Il y a un problème. (There's a problem.) Il y a trois pommes sur la table. (There are three apples on the table.) Il y a beaucoup de monde ce soir. (There are a lot of people tonight.) Il y avait une fois… (Once upon a time…, literally "there was once".)
Il y a is invariable. It never changes for singular vs plural (il y a une chose / il y a trois choses) and it never changes for gender. It only changes for tense:
| Tense | Form |
|---|---|
| Présent | il y a |
| Passé composé | il y a eu |
| Imparfait | il y avait |
| Futur simple | il y aura |
| Conditionnel | il y aurait |
| Subjonctif | qu'il y ait |
Bonus use: "ago"
il y a + duration = "ago".
Je l'ai vu il y a trois jours. (I saw him three days ago.) Il y a longtemps que je n'ai pas mangé. (It's been a long time since I ate.)
C'est, "it is / he is / she is" + noun or adjective standing alone
Use it for identification or general description, especially when followed by a noun (with article) or a standalone adjective.
C'est Marie. (It's Marie. / That's Marie.) C'est mon frère. (That's my brother.) C'est un bon restaurant. (It's a good restaurant.) C'est délicieux. (It's delicious., general/abstract: "this whole thing is delicious".) C'est intéressant, ce film. (That movie is interesting.)
Ce sont for plurals
In careful French, c'est becomes ce sont when the following noun is plural:
Ce sont mes amis. (They are my friends.) Ce sont des livres anciens. (They are old books.)
In casual speech you'll hear c'est mes amis constantly. That's spoken French taking a shortcut. Use ce sont in writing.
The rule: c'est = unspecified "it"
The trick: c'est refers to the situation as a whole, not a specific noun you've already named. "C'est délicieux" doesn't refer to a specific dish, it refers to the whole eating experience. Same for "c'est intéressant": the topic itself, not one particular thing.
Il est, "he is / it is" + adjective referring to a specific noun, OR time
Il est is the trickiest of the three because it has two distinct uses.
Use 1: Identifying a specific person or thing with an adjective
When the adjective describes a specific noun you've already mentioned, use il est / elle est and match the gender + number.
Tu vois ce gâteau ? Il est délicieux. (See that cake? It's delicious.,
il=le gâteau.) Tu connais Marie ? Elle est sympa. (You know Marie? She's nice.) Les enfants ? Ils sont dans le jardin. (The kids? They're in the garden.)
Compare:
C'est délicieux. (It's delicious., general, unspecified.) Ce gâteau ? Il est délicieux. (That cake? It's delicious., specific.)
💡 The rule of thumb:
c'est+ adjective stands alone.il/elle/ils/elles est/sont+ adjective comes after you've named the specific thing.
Use 2: Telling time
For the clock time only, use il est. Never c'est.
Il est huit heures. (It's 8 o'clock.) Il est midi. (It's noon.) Quelle heure est-il ? (What time is it?)
But for days, dates, and parts of day, switch to c'est:
C'est lundi. (It's Monday.) C'est le 14 juillet. (It's July 14th.) C'est le matin. (It's morning.)
Use 3: Professions and nationalities (the c'est / il est split)
This is the one beginners get wrong constantly.
| Pattern | Use | Example |
|---|---|---|
Il est + profession/nationality without an article |
When stating a quality | Il est médecin. (He's a doctor.) |
C'est + un/une + profession/nationality |
When introducing/identifying | C'est un médecin. (He's a doctor / a doctor.) |
C'est + un/une + profession + adjective |
When qualifying | C'est un bon médecin. (He's a good doctor.) |
Il est français. → C'est un Français. Elle est avocate. → C'est une avocate brillante.
The pattern: no article → il est. Article (un/une/le/la) → c'est.
The decision tree
When you want to say "it is / there is" in French, ask in this order:
- Does something exist or are you talking about quantity? →
il y a - Are you telling time on a clock? →
il est - Are you describing a specific noun already mentioned, with an adjective and no article? →
il/elle est(matching gender) - Are you stating a profession/nationality without an article? →
il/elle est - Everything else (identification, general description, "it's [adjective]" in a vacuum, days/dates, professions with
un/une) →c'est
Side-by-side examples
| English | Wrong | Right | Why |
|---|---|---|---|
| There's a cat in the garden. | C'est un chat… | Il y a un chat dans le jardin. | Existence. |
| It's a cat. | Il est un chat. | C'est un chat. | Identification + article. |
| It's beautiful (the view). | Il est beau. | C'est beau. | Standalone adjective, no specific noun. |
| The view? It's beautiful. | C'est belle. | La vue ? Elle est belle. | Specific noun (la vue, feminine). |
| It's 3 o'clock. | C'est trois heures. | Il est trois heures. | Clock time. |
| It's Monday. | Il est lundi. | C'est lundi. | Day, not clock time. |
| She's a doctor. | Elle est une médecin. | Elle est médecin. or C'est une médecin. | No article → il/elle est. Article → c'est. |
| There were a lot of people. | C'étaient beaucoup… | Il y avait beaucoup de monde. | Existence + quantity. |
Why this confuses English speakers
English uses "it is" for all of these. We don't distinguish identification from description from existence from time-telling, context handles it. French splits them across three structures, and which one you reach for is the difference between sounding fluent and sounding like a beginner.
The good news: there are only three options, and the decision tree above covers 95% of real-world cases. The other 5% are corner cases native speakers themselves disagree on.
The Bonjour Verbs app drills être and avoir, the verbs that power all three of these expressions, across every tense, with sentence-completion practice that includes c'est / il est / il y a choices in context. After enough reps, you stop reaching for the wrong one.
