French Indefinite Pronouns: A Complete Guide for Learners

Key takeaways

• French indefinite pronouns refer to unspecified people or things: quelqu’un (someone), quelque chose (something), personne (no one), rien (nothing). The negative ones (personne, rien) always require ne before the verb.
• Personne and rien are indefinite pronouns when they appear alone, not nouns. Je ne vois personne (I see no one) uses personne as a pronoun, not as a reference to a person.
• Tout as a pronoun means “everything” or “everyone” depending on context and agrees differently: tout (everything, singular verb), tous/toutes (all of them, plural verb with a pronounced s in tous).
• Indefinite pronouns used as subjects take a third-person singular verb (quelqu’un parle, chacun décide), even when they refer to multiple people in meaning.

Indefinite pronouns do a specific job: they stand in for people or things without identifying them. In English, most learners use “someone, something, no one, nothing, everyone” without thinking.

In French, the same job is shared across several pronouns with different grammatical behaviors, and the negative ones (personne, rien) work in a way that regularly produces errors, because they need ne even though they already look negative.

This guide covers French indefinite pronouns grouped by grammatical type: quelqu’un and quelque chose, the negative pronouns personne and rien with the ne rule and their different positions in compound tenses, chacun, the tout/tous/toutes group with agreement and pronunciation distinctions, plusieurs and certains, the n’importe qui/quoi/où group, and quelques-uns.

The errors these pronouns produce in conversation, missing ne, wrong verb agreement, confusing tout and tous, accumulate into habits without correction because they usually don’t block communication enough for the speaker to notice. Working with a private French tutor on italki, which has connected over 10 million learners with qualified teachers since 2007, creates the real-speech context where these patterns are caught and corrected before they solidify.

Quelqu’un and quelque chose: someone and something

Quelqu’un (someone, somebody) and quelque chose (something) are the most basic indefinite pronouns. Both are grammatically singular and take a third-person singular verb.

Quelqu’un a appelé pendant ton absence. (Someone called while you were out.) Quelque chose ne va pas. (Something is wrong.) Est-ce que quelqu’un peut m’aider? (Can someone help me?) J’ai quelque chose à te dire. (I have something to tell you.)

Adding adjectives: When an adjective follows quelqu’un or quelque chose, it must be masculine singular and preceded by de:

quelqu’un d’intéressant (someone interesting) quelque chose de bizarre (something strange) quelqu’un de qualifié (someone qualified) quelque chose d’important (something important)

The de before the adjective is obligatory. Quelque chose important (without de) is wrong.

Personne and rien: no one and nothing

These are the negative indefinite pronouns. They always require ne before the verb, even though their meaning is already negative. This is a double negation structure that is standard in French, not redundant.

Personne (no one, nobody):

Je ne vois personne. (I see no one. / I don’t see anyone.) Personne n’est venu. (No one came.) Il n’a parlé à personne. (He didn’t speak to anyone.)

When personne is the subject of a sentence, ne still appears before the verb: Personne ne sait. (No one knows.)

Rien (nothing):

Il n’a rien dit. (He said nothing. / He didn’t say anything.) Rien n’est impossible. (Nothing is impossible.) Je n’entends rien. (I hear nothing. / I can’t hear anything.)

Position with compound tenses: Personne follows the past participle (je n’ai vu personne), but rien comes before the past participle (je n’ai rien dit). This difference is one of the most persistent errors among French learners.

J’ai vu personne. (missing ne, wrong) Je n’ai vu personne. (correct) Je n’ai pas dit rien. (wrong: pas and rien cannot both appear) Je n’ai rien dit. (correct)

A French language tutor can run dialogue exercises where personne and rien appear in compound tenses, giving immediate correction each time the ne is dropped or rien lands in the wrong position. italki has 30,000+ teachers across 150+ languages, including qualified French teachers who target these common grammar patterns in structured conversation.

Chacun and chaque: each one and each

Chacun (masculine) and chacune (feminine) mean “each one.” They are pronouns and take a singular verb.

Chacun a reçu une invitation. (Each one received an invitation.) Chacune a ses préférences. (Each one [feminine] has her preferences.) Chacun fait ce qu’il peut. (Each does what they can.)

Chaque is an adjective, not a pronoun. It is always followed by a singular noun:

Chaque personne a voté. (Each person voted.) Chaque jour est différent. (Each day is different.)

The distinction: chacun stands alone (pronoun), chaque must precede a noun (adjective).

Tout, tous, toutes: all and everything

Tout covers several related meanings and changes form depending on its function:

Tout (pronoun, singular, means “everything”): Tout est prêt. (Everything is ready.) Il mange tout. (He eats everything.) J’ai tout compris. (I understood everything.)

Tous / toutes (pronoun, plural, means “all of them”): Ils sont tous arrivés. (They all arrived.) Les filles sont toutes venues. (All the girls came.) Je les ai tous vus. (I saw all of them.)

Critical pronunciation note: When tous is an adjective (tous les jours = every day), the final -s is silent. When tous is a pronoun (ils sont tous venus = they all came), the final -s is pronounced. This distinction in pronunciation signals to listeners whether tous is an adjective or a pronoun.

For the imperative constructions that use tout and other pronouns in instructions (faites tout ce qu’on vous dit = do everything you’re told), the guide to French imperative verbs covers how commands are formed and how pronouns attach to them.

Plusieurs and certain(e)s: several and some

Plusieurs (several) is invariable (same form for masculine and feminine) and always plural:

Plusieurs ont refusé. (Several refused.) J’en ai plusieurs. (I have several of them.) Plusieurs de mes amis habitent à Lyon. (Several of my friends live in Lyon.)

Certain(e)s (some, certain ones) agrees in gender and number. As a pronoun, it refers back to a group already mentioned:

Certains pensent que c’est faux. (Some think it’s wrong.) Certaines de mes collègues sont d’accord. (Some of my [female] colleagues agree.) Certains aiment le café, d’autres préfèrent le thé. (Some like coffee, others prefer tea.)

The combination certains… d’autres (some… others) is a very common structure for expressing contrasting groups.

N’importe qui, n’importe quoi, n’importe où: any at all

These pronouns express indifference or universality, the idea that any option, person, or place would do.

Pronoun	Meaning	Example
n’importe qui	anyone, just anyone	N’importe qui peut participer. (Anyone can participate.)
n’importe quoi	anything, whatever	Ne mange pas n’importe quoi. (Don’t eat just anything.)
n’importe où	anywhere, wherever	On peut se retrouver n’importe où. (We can meet anywhere.)
n’importe quand	any time, whenever	Appelle-moi n’importe quand. (Call me any time.)
n’importe comment	in any way, carelessly	Il fait son travail n’importe comment. (He does his work carelessly.)

N’importe quoi also functions as a standalone exclamation meaning “that’s nonsense” or “that’s ridiculous”: N’importe quoi! This use is very common in informal spoken French.

Quelques-uns and quelques-unes: some, a few

Quelques-uns (masculine/mixed group) and quelques-unes (feminine) mean “some” or “a few” and always refer to a plural quantity. They agree in gender with the noun they represent.

Quelques-uns sont partis tôt. (Some [of them] left early.) J’ai lu quelques-uns de ses romans. (I’ve read some of his novels.) Quelques-unes de ces idées sont bonnes. (Some of these ideas are good.)

Do not confuse with quelques (adjective, before a noun): quelques amis (a few friends). Quelques-uns stands alone (pronoun).

Common mistakes

Error	Correct form	Rule
Je vois personne.	Je ne vois personne.	Personne always needs ne
Je n’ai pas dit rien.	Je n’ai rien dit.	Rien replaces pas, never combines with it
J’ai rien compris.	Je n’ai rien compris.	Ne required with rien
Quelque chose intéressant.	Quelque chose d’intéressant.	De required before adjective
Chacun ont fini.	Chacun a fini.	Chacun takes singular verb
Tous sont venus (silent s)	Tous sont venus (pronounced s)	Tous as pronoun has pronounced s

Putting these pronouns into conversation

The errors that come from missing ne, misplacing rien, or mispronouncing tous are the kind that accumulate into habits. The way they stop appearing is through real conversation with correction, not through rereading a grammar table.

FAQ

Is it ever acceptable to omit ne with personne and rien in spoken French?

In very informal spoken French, ne is frequently dropped: Je vois personne and J’ai rien compris are heard constantly in casual speech. However, written French and formal contexts require the full ne…personne and ne…rien structure. Learners should recognize the spoken version but produce the full form in writing and in intermediate-to-advanced practice.

What is the difference between quelqu’un and on?

Quelqu’un means a specific but unidentified person: quelqu’un a téléphoné (a specific person called, we don’t know who). On is more general and can mean “people in general,” “one,” “we,” or “they” depending on context: on dit que… (they say that / people say that). The two are not interchangeable.

Does rien change its position in negative sentences with compound tenses?

Yes, and this is one of the most important things to learn about rien. In compound tenses, rien comes between the auxiliary and the past participle: Je n’ai rien dit (I said nothing). Personne, by contrast, follows the past participle: Je n’ai vu personne (I saw no one).
