What does fuir mean?

A faucet in profile, with a drop of water coming out of it and water on top of it and around it, too. Has it just been used? Has it been under the rain since it seems to be outside due to the blurred green background? Or is it leaking?

Fuir means “to avoid”, “to flee”, or “to leak”.

For instance:

Il est plutôt solitaire, il fuit les foules. (He’s a rather solitary person; he avoids/gets himself far away from crowds.)

In a sort of related way,  fuir can also be used to describe something that leaks. For example: Il faut remplacer ce tuyau, il fuit. (We need to replace this pipe, it’s leaking.). As in English, this sense of leaking can be literal or figurative, as you can see in expressions like une fuite dans la presse (a press leak).

Two common words related to fuir

Two words related to fuir that you’ll often come across and use are:

Une fuite is the noun form of fuir. It can mean “running away” or “fleeing” or “a leak”.  As with its verb form, this can be used literally or figuratively.

For instance:  Il y a une fuite d’eau dans la cave. (There’s a water leak in the basement.)  Or La fuite du temps est une chose qu’on ressent tous avec l’âge. (Time’s fleeing is something we all feel, especially when we get old.)

As you can see, when you want to say what is leaking, you put it after de . For instance, une fuite de gaz is “a gas leak”.

The other common fuir-related word, s’enfuir, is a verb that also means “to flee”, but this time it takes on a context of escaping, rather than avoiding.

For instance: Face au dragon, le brave chevalier a perdu tout son courage et il s’est enfui. (Face-to-face with the dragon, the brave knight lost all of his courage and ran away.)

Let’s look at how to conjugate s’enfuir.

S’enfuir conjugation

A man dressed as a knight in golden armor, with a small painted wooden shield and riding a white horse, looks out over a field with what appears to be an old stone wall in the distance. He holds a red pennant high in the air.
Face au dragon, le brave chevalier a perdu tout son courage et il s’est enfui.

S’enfuir is conjugated the same way as fuir, with one notable exception. Since it’s a reflexive verb, it uses être as an auxiliary (as opposed to avoir). This means, among other things, that in compound tenses, the participle has to agree with the subject.

Here’s how to conjugate the most common tenses of s’enfuir.

What is the difference between fuir and s’enfuir?

A spiral of barbed wire with a low building and a mountain around it. It seems to be a prison gate.

There are two main differences between fuir and s’enfuir.

Fuir means “to flee” in the sense of avoidance

Fuir means “to flee” in the sense of avoidance whereas s’enfuir means “to flee” in the sense of “to escape.” This means s’enfuir is usually used to describe the action of actively escaping whereas fuir tends to be more passive.

To put it another way, some synonyms of fuir could be esquiver or éviter, while a synonym of s’enfuir could be s’échapper.

Here’s an example of how each word is used:

Il a fui son pays ravagé par la guerre.

He escaped his war-torn country.

Il a réussi à s’enfuir.

He managed to escape/run away.

2. Fuir isn’t followed by de but s’enfuir is

As you might have noticed from the examples in this section, another difference between fuir and s’enfuir is that fuir is directly followed by a noun, while s’enfuir has to be followed by de plus an article and then the noun.
