French Word of the Day – Il faut – It’s necessary, one must

📘 Il faut meaning

In French, il faut is an impersonal expression meaning it is necessary or one must. The il translates as “it” but doesn’t refer to anything specific, and the phrase expresses obligation, necessity, or advice, followed by an infinitive, a noun, or que + subjunctive. (See examples below.)

🎧 Il faut pronunciation

Il faut is pronounced /il fo/ and sounds like eel foh, with a clear long oh at the end.

📝 French and English examples

Il faut – it’s necessary, one must

Il faut + infinitive is used to express a general obligation or necessity without addressing anyone in particular.

1. Il faut + infinitive

Il faut travailler pour réussir dans la vie!
You have to work to succeed in life.

2. Il faut que + subjunctive

Il faut que is an impersonal expression that requires the subjunctive. It’s usually translated as one must, it’s necessary to, or you have to.

Il faut que tu fasses attention.
You need to pay attention.

3. Il faut quelque chose à quelqu’un

The structure “il faut quelque chose à quelqu’un” is very similar to “avoir besoin de,” which means “to need.” Here, “à quelqu’un” is the indirect object.

For example, “Il faut une voiture à Pierre” becomes “Il lui faut une voiture,” or “He needs a car.” This pattern uses indirect object pronouns.

Il me faut une fourchette pour manger le steak.
I need a fork to eat the steak.

Il faut in different tenses

In addition to these three uses, il faut can also appear in tenses other than the present.

Future tense

In the futur simple, il faut becomes il faudra.

Il faudra que tu travailles demain.
You’ll have to work tomorrow.

Near future tense

The futur proche (near future) is formed with “aller + infinitive.” For “il faut,” the infinitive is “falloir,” which means “to be necessary.”

Il va falloir que tu fasses quelque chose.
You’re doing to have to do something.

Passé composé

In the passé composé, “il faut” becomes “il a fallu,” which translates as “it was necessary to.”

Il a fallu acheter la voiture.
It was necessary to buy the car.

Imperfect

Il faut” can also be used in the imperfect tense, where it appears as “il fallait.” This sentence can be loosely translated as “You should have said something.”

Il fallait dire queque chose.
It was necessary to say something.

Past conditional

In the past conditional, il faut becomes il aurait fallu, which literally translates as “it would have been necessary”. In practice, this often conveys the idea of “should have”.

Il aurait fallu acheter la maison l’année dernière.
We should have bought the house last year.
