What does soi mean in French?

Oneself, or yourself in the general sense. It is the stressed pronoun used when the subject is indefinite: on rentre chez soi, chacun pour soi, il faut avoir confiance en soi.

When do I use soi instead of lui?

When the subject of the clause is on, chacun, tout le monde, personne, quiconque, celui qui, or an infinitive with no subject. With a named person or a definite pronoun, use lui or elle: il pense à lui.

What is the difference between soi and sois?

Soi is a pronoun; sois is the tu imperative and subjunctive of être. Sois prudent means be careful, while penser à soi means to think of oneself. Soit and soie are two more homophones with different jobs again.

What does en soi mean?

In itself, considered on its own: l'idée n'est pas mauvaise en soi. It applies to things rather than people, and the related cela va de soi means that goes without saying.

What does soi-disant mean?

So-called or supposedly. It is invariable and always hyphenated: un soi-disant spécialiste, des soi-disant réformes. It implies doubt, so it is not a neutral way of saying apparently.

Soi in French: The Stressed Pronoun for an Impersonal Subject

Written by Camille Laurent, Lead French Curriculum Editor · Reviewed May 2026

Soi is the stressed pronoun used when the subject is nobody in particular: on, chacun, tout le monde, personne, or an infinitive. Where a named subject takes lui or elle, an impersonal one takes soi, and it turns up in a long list of fixed phrases from chez soi to cela va de soi.

Après le travail, chacun rentre chez soi.

After work, everyone goes home.

What it is

The stressed pronouns moi, toi, lui and elle all name someone specific. Soi is the one that names nobody: it refers back to a subject that is general or unidentified, which is why it pairs with on, chacun and il faut rather than with je or Marie.

Il faut savoir compter sur soi. — You have to know how to rely on yourself.

How to spot it

Look at the subject. If it is a named person or a definite pronoun, use lui or elle. If it is on, chacun, tout le monde, personne, celui qui, or an infinitive with no subject at all, use soi.

Chacun pour soi. — Every man for himself.
On pense trop à soi. — People think too much about themselves.
Il faut avoir confiance en soi. — You have to believe in yourself.
Il rentre chez lui. — He's going home. (a specific person, so lui)

Soi is invariable: there is no feminine or plural form, because it refers to a subject with no identity to agree with.

Common Stressed Pronoun Soi Examples in French

Soi with the impersonal subjects that call for it:

After a Preposition

On n'a pas toujours confiance en soi.: You don't always have confidence in yourself.
Il faut penser à soi de temps en temps.: You have to think about yourself now and then.
Chacun garde ses papiers sur soi.: Everybody keeps their papers on them.
Travailler pour soi demande de la discipline.: Working for yourself takes discipline.

This is where soi lives: after avec, chez, pour, en, sur, à and de, when the subject is anybody at all.

Chez Soi

Il est agréable de rentrer chez soi.: It's nice to get home.
On est mieux chez soi.: You're better off at home.
Chacun est parti chez soi après le dîner.: Everyone went home after dinner.
Personne ne se sent chez soi ici.: Nobody feels at home here.

Compare il rentre chez lui, with a specific subject. Chez soi always implies an unnamed or generic person.

Soi-même for Emphasis

Il vaut mieux le faire soi-même.: It's better to do it yourself.
On ne se connaît jamais soi-même complètement.: You never fully know yourself.
Chacun doit décider par soi-même.: Everyone has to decide for themselves.
Cuisiner soi-même coûte moins cher.: Cooking for yourself is cheaper.

Soi-même adds the sense of personally, without help. It takes a hyphen and never a plural s.

En Soi, Meaning in Itself

L'idée est bonne en soi.: The idea is a good one in itself.
Ce n'est pas grave en soi, mais c'est symbolique.: It isn't serious in itself, but it's symbolic.
La règle n'est pas absurde en soi.: The rule isn't absurd in itself.
Cela va de soi.: That goes without saying.

En soi is used of things rather than people and means considered on its own, apart from its consequences.

How Soi Works

It is a stressed pronoun with one restriction: its subject has to be nobody in particular.

It Refers Back to an Indefinite Subject

Soi is reflexive in the sense that it points back to the subject of its own clause, but only when that subject is generic. On, chacun, tout le monde, personne, celui qui and quiconque all license it.

Quiconque a vécu à l'étranger sait ce qu'on ressent loin de chez soi.

Anyone who has lived abroad knows what it feels like far from home.

Generic subject → soi.

An Infinitive Counts as Indefinite

An infinitive has no subject of its own, so anything reflexive attached to it takes soi. Travailler pour soi, parler de soi, garder pour soi are all built this way.

Il est difficile de parler de soi sans exagérer.

It's hard to talk about yourself without exaggerating.

Infinitive with no subject → soi.

It Never Changes Form

Because the subject has no gender or number, soi has none either. There is no soie in this sense, no plural, and soi-même keeps its singular même whatever the size of the group it applies to.

Tout le monde doit apprendre à s'occuper de soi.

Everybody has to learn to look after themselves.

One form, always.

With a Named Subject, Use Lui or Elle

As soon as the subject is identified, soi is replaced by the ordinary stressed pronoun. Marc parle de lui, elle pense à elle, ils travaillent pour eux. Using soi there sounds like a translation error.

Elle ne parle que d'elle.

She only talks about herself.

Named subject → lui, elle, eux, elles.

Soi Is Not the Reflexive Object Pronoun

The reflexive object pronoun is se: on se lave, chacun s'habille. Soi appears only after a preposition or with -même, never directly in front of the verb.

On se prépare, puis on rentre chez soi.

You get ready, then you go home.

se before the verb, soi after a preposition.

Common Mistakes with Stressed Pronoun Soi

Incorrect: Il rentre chez soi après le travail. — He goes home after work.

Correct: Il rentre chez lui après le travail. — He goes home after work.

The subject il is a specific person, so the stressed pronoun is lui. Soi requires an indefinite subject such as on or chacun.

Incorrect: On se lave soi le matin. — You wash in the morning.

Correct: On se lave le matin. — You wash in the morning.

Soi cannot be the direct object of a verb. The reflexive object pronoun is se, and soi only appears after a preposition or with -même.

Incorrect: Soi patient, ça va venir. — Be patient, it'll come.

Correct: Sois patient, ça va venir. — Be patient, it'll come.

The imperative of être is sois, with an s. Soi is only a pronoun and cannot be a verb form, despite sounding identical.

Incorrect: Ils sont partis chacun chez soi-mêmes. — They each went home.

Correct: Ils sont partis chacun chez soi. — They each went home.

Soi is invariable and takes no plural s, and -même is not needed here since there is no emphasis on doing something personally.

Fixed Phrases and a Spelling Trap

Soi anchors a set of common expressions, and it has three homophones that mean entirely different things.

Expressions worth learning whole

In these, soi is fixed and no other pronoun can be substituted, even when the subject is a specific person.

Cela va de soi.: That goes without saying.
Chacun pour soi et Dieu pour tous.: Every man for himself.
Il n'est pas très sûr de soi.: He isn't very sure of himself.
Rester maître de soi est difficile.: Keeping your self-control is hard.

Confiance en soi and maîtrise de soi have become nouns in their own right, meaning self-confidence and self-control.

Soi, soit, sois and soie

Four words sound alike and none of them is interchangeable. Soi is the pronoun; sois is the tu imperative or subjunctive of être; soit is the third person subjunctive or the word meaning either; soie is silk.

Sois patient, s'il te plaît.: Be patient, please.
Il faut qu'il soit là à huit heures.: He has to be there at eight.
Soit l'un, soit l'autre.: Either one or the other.
Une écharpe en soie.: A silk scarf.

Only soi is a pronoun. The others are forms of être, a conjunction, or a noun.

Soi-disant, so-called

Soi-disant is an invariable adjective and adverb meaning supposedly or self-styled. It is written with a hyphen and never agrees, whatever it describes.

un soi-disant expert: a so-called expert
des soi-disant améliorations: supposed improvements
Il est soi-disant malade.: He's supposedly ill.

Soi-disant carries scepticism. For a neutral supposedly, French uses prétendument or apparemment.
