When you want to say the one I want, the ones who left, Marie's [book], or that one over there, French reaches for the demonstrative pronoun: celui / celle / ceux / celles. These four forms — masculine singular, feminine singular, masculine plural, feminine plural — function as a kind of pointing finger combined with the definite article. They mean roughly the one(s), but with a built-in demonstrative force that says that specific one, the relevant one, the one we both know about.
The single most important fact about celui is that it cannot stand alone. Every celui in French must be immediately followed by one of three qualifiers: a hyphenated -ci or -là, a relative pronoun (qui, que, dont, où), or a de + noun phrase. A bare celui is ungrammatical. This rule is why English speakers struggle with the construction — English happily says I want the red one, with one standing on its own; French requires the qualifier.
The forms
| Singular | Plural | |
|---|---|---|
| Masculine | celui | ceux |
| Feminine | celle | celles |
The form agrees with the noun it replaces, not with anything else in the sentence. Le livre → celui; la robe → celle; les enfants → ceux; les voitures → celles. Pronunciation: celui /sə.lɥi/, celle /sɛl/, ceux /sø/, celles /sɛl/. Note that celle and celles are pronounced identically — the plural is visible only in writing — exactly like the difference between la and les mostly being audible only in liaison contexts.
There is no neutral form. When you want to point to something whose noun isn't specified or is abstract, you don't use celui — you use the neutral demonstratives ce / ça / cela (covered separately on the page on those forms).
Pattern 1: celui-ci, celui-là (this one, that one)
Adding -ci or -là turns the demonstrative into a deictic pointer — this one (near) versus that one (far). In careful French the -ci/-là contrast is real: celui-ci refers to the closer or more recently mentioned item, celui-là to the farther or earlier one. In everyday spoken French the contrast is largely neutralized, and celui-là dominates as the all-purpose "that one."
Quelle robe tu préfères ? — Celle-ci.
Which dress do you prefer? — This one.
J'hésite entre deux livres. Celui-ci est passionnant, mais celui-là est plus court.
I'm hesitating between two books. This one is gripping, but that one is shorter.
Tu vois ces deux maisons ? Celle de gauche est à mes parents, celle-là à mes voisins.
See those two houses? The one on the left is my parents', that one is my neighbors'.
Ces chaussures, je les essaie toutes — celles-ci sont trop serrées, celles-là me vont parfaitement.
These shoes — I'm trying them all on — these ones are too tight, those ones fit me perfectly.
Note the writing convention: celui-ci, celle-là, ceux-ci, celles-là are written with a hyphen. Without the hyphen, you have ungrammatical strings.
A useful idiomatic application: in narrative, celui-ci/celle-ci is used to refer to the most recently mentioned person, the way English uses the latter. Pierre est venu avec Marie ; celle-ci portait une robe rouge — Marie (the latter) was wearing a red dress. This usage is more common in writing than in speech.
Le directeur a appelé son assistant ; celui-ci est arrivé tout de suite.
The director called his assistant; the latter came right away.
Pattern 2: celui qui, celui que, celui dont (the one who/that)
Followed by a relative pronoun, celui introduces a relative clause that selects the relevant referent. This is the highest-frequency use of celui — it is what makes the form indispensable in French.
The relative pronoun follows the same rules as in any other relative clause: qui for subject, que for direct object, dont for de-relations, où for place/time, à qui / avec qui / pour qui for prepositional relations.
Celui qui parle est mon frère.
The one who's speaking is my brother.
Celle que j'aime ne le sait pas encore.
The one I love doesn't know it yet.
Ceux qui veulent partir, levez la main.
Those who want to leave, raise your hand.
Celles qui ont fini peuvent sortir.
The girls who have finished can leave.
C'est celui dont je t'ai parlé hier.
It's the one I talked to you about yesterday.
Voilà la maison ; celle où j'ai grandi est juste à côté.
Here's the house; the one I grew up in is right next door.
The key insight: celui qui is doing the work of English "the one who", "those who", or "whoever". Celui qui parle bien réussit — "Whoever speaks well succeeds" / "The one who speaks well succeeds." French has no separate word for whoever — it just uses celui qui with a generalizing reading.
A subtler case: celui que with the participle of être or a noun phrase, expressing identification:
Tu as vu ce film ? — Bien sûr, c'est celui que tout le monde recommande.
Have you seen this film? — Of course, it's the one everyone recommends.
Ce ne sont pas les conseils que je voulais ; ceux que je cherchais étaient plus précis.
These aren't the suggestions I wanted; the ones I was looking for were more specific.
Pattern 3: celui de + noun (X's [one])
Followed by de + noun, celui expresses possession or origin: celui de Marie = "Marie's (one)", celui du voisin = "the neighbor's (one)". This construction is how French handles possessive comparisons that English builds with 's.
Le livre de Pierre et celui de Marie sont sur la table.
Pierre's book and Marie's are on the table.
Mes parents et ceux de mon mari arrivent demain.
My parents and my husband's are arriving tomorrow.
Ta voiture est en panne ? Prends celle de ton père.
Your car broken down? Take your father's.
Cette idée n'est pas la mienne, c'est celle d'Émilie.
This idea isn't mine, it's Émilie's.
The pattern extends to places, times, and kinds, not only people:
Le climat de la France et celui de l'Italie sont assez différents.
The climate of France and that of Italy are quite different.
L'éducation des enfants d'aujourd'hui n'est plus celle des années cinquante.
The education of today's children is no longer that of the 1950s.
Le prix de cette voiture est plus élevé que celui de la version précédente.
The price of this car is higher than that of the previous version.
A useful sub-pattern: prepositional phrase as qualifier, where the de phrase is replaced by en, à, avec, sur, etc. — though strict grammarians have debated whether this is fully accepted.
Quel pull tu prends ? — Celui en laine, je crois.
Which sweater are you taking? — The wool one, I think.
La maison à droite, c'est la mienne ; celle de gauche est à louer.
The house on the right is mine; the one on the left is for rent.
Celle de droite est plus belle que celle de gauche.
The one on the right is prettier than the one on the left.
In modern usage celui en laine, celui à pois, celui avec un col rond are universally accepted. Older grammarians sometimes objected; the language has moved on.
Pattern 4: celui + adjective (literary)
In literary or formal French, celui can occasionally appear directly before an adjective: les jours heureux et ceux malheureux, les voix des hommes et celles tristes des femmes. This usage is archaic in everyday speech — modern French would prefer celui qui est X or restructure the sentence.
Les jours heureux et ceux malheureux se mêlent dans nos souvenirs.
The happy days and the unhappy ones blend together in our memories. (literary)
Les jours heureux et ceux qui sont malheureux se mêlent dans nos souvenirs.
The happy days and those that are unhappy blend together in our memories. (modern equivalent)
For B1–B2 production, avoid the bare celui + adjective construction; use celui qui est + adjective or restructure with les + noun + adjectif. Recognize the literary form when you read it.
What celui does NOT do
A common transfer error: English uses the one loosely, including in contexts where French requires a different construction.
English I want the big one → French je veux le grand (using the substantivized adjective, NOT celui grand). English the red one → French le rouge (NOT celui rouge).
When the qualifier is a single adjective and there's no relative clause involved, French simply substantivizes the adjective with the definite article. Celui enters when you have a relative clause (celui qui est rouge) or a de-phrase (celui de Pierre).
Je voudrais le rouge, s'il vous plaît.
I'd like the red one, please. (NOT *celui rouge*)
Tu prends les grandes ou les petites ? — Les grandes.
Are you taking the big ones or the small ones? — The big ones. (NOT *celles grandes*)
If you want to combine the adjective with a relative clause, then celui returns: celui qui est rouge, ceux qui sont grands. The rule is mechanical: bare adjective qualifier → substantivized adjective; everything else → celui + qualifier.
English-French alignment
For an English speaker, the cleanest way to think about celui is to map it onto English "the one(s)" plus the qualifier that English would use:
| English | French |
|---|---|
| this one / that one | celui-ci / celui-là |
| the one who speaks | celui qui parle |
| the one I love | celui que j'aime / celle que j'aime |
| the one I'm thinking of | celui auquel je pense / celui à qui je pense |
| the one I'm talking about | celui dont je parle |
| the one in the kitchen | celui de la cuisine / celui qui est dans la cuisine |
| Marie's [book] | celui de Marie |
| those who want to leave | ceux qui veulent partir |
The mismatch English speakers most often miss: French celui is gendered. The English the one is gender-neutral, so an English speaker may automatically reach for celui for everything, producing errors like celui que j'aime when the referent is la robe (which requires celle que j'aime). Always ask yourself: what noun does this celui replace?, and let that noun's gender and number decide the form.
Common Mistakes
❌ Je veux celui rouge.
Incorrect — bare adjective requires substantivized adjective, not *celui*.
✅ Je veux le rouge.
I want the red one.
When the qualifier is a single bare adjective, drop celui and use le/la/les + adjective. Celui needs a relative clause, de phrase, or -ci/-là to license it.
❌ Celui parle est mon frère.
Incorrect — missing the relative pronoun *qui*.
✅ Celui qui parle est mon frère.
The one who's speaking is my brother.
A bare celui + verb is ungrammatical. The relative pronoun qui is mandatory.
❌ Le livre de Pierre et celui Marie.
Incorrect — missing *de* before *Marie*.
✅ Le livre de Pierre et celui de Marie.
Pierre's book and Marie's.
The celui de + noun construction must always include de. English has Pierre's and Marie's with the apostrophe-s carrying the possession; French uses the de preposition.
❌ La robe rouge est belle ; celui que j'ai acheté hier est moche.
Incorrect — *la robe* is feminine, so the pronoun is *celle*, not *celui*.
✅ La robe rouge est belle ; celle que j'ai achetée hier est moche.
The red dress is pretty; the one I bought yesterday is ugly.
Agreement is with the noun replaced. Note also the participle agreement (achetée) with the preceding direct object celle.
❌ Ce qui m'intéresse n'est pas celui-ci.
Awkward — when there's no specific noun in mind, the neutral *cela* / *ça* is preferred.
✅ Ce qui m'intéresse, ce n'est pas ça.
What interests me isn't that.
Celui always replaces a specific gendered noun. For abstract or unspecified referents, French reaches for the neutral demonstratives ce, ça, cela.
❌ Les enfants qui jouent et qui pleurent.
Incomplete — if the contrast is two groups, you need *celui*.
✅ Ceux qui jouent et ceux qui pleurent.
Those who play and those who cry.
When the contrast is between two distinct groups (or two distinct referents), each side needs its own celui qui. The first les enfants establishes the noun; ceux picks up the second group.
Key Takeaways
- Celui (m.sg.), celle (f.sg.), ceux (m.pl.), celles (f.pl.) replace a noun and agree with the noun replaced — not with the speaker, not with anything else.
- Celui never stands alone. It must be followed by -ci/-là (this one / that one), a relative clause (qui parle, que je vois, dont je parle, où je vais), or a de phrase (celui de Marie).
- For bare adjectives ("the red one"), drop celui and use the substantivized adjective (le rouge).
- Celui qui and ceux qui are how French says whoever / those who / the ones who — there is no separate word.
- The celui de + noun construction is how French expresses English 's possession in pronoun position (Marie's [one] = celui de Marie).
- The literary celui + adjective construction (ceux malheureux) is recognized in reading but avoided in modern production.

- Ce, ça, cela: The Neutral DemonstrativesA1 — These three forms cover everything English does with 'it', 'this', and 'that' when there's no specific gendered noun in play. Ce attaches only to être (c'est, ce sont). Ça is the conversational workhorse. Cela is its written, formal twin. Mastering the trio is the difference between sounding French and sounding translated.
- Qui vs Que: The Subject/Object Relative PronounsA2 — These two short words carry the entire weight of basic French relative clauses. Qui is for subjects, que is for direct objects. The distinction is mechanical once you see it: replace the antecedent inside the clause and ask whether it would be the doer or the receiver of the verb. Mastering this contrast is the gateway to fluent French syntax.
- Dont: The De-Relative PronounB1 — Dont is the relative pronoun that replaces 'de + noun' inside a relative clause. It does the work of English 'whose', 'of which', 'about whom', 'from which', and several other prepositional relatives — all in one word. Mastering dont is the moment your French syntax stops sounding intermediate and starts sounding fluent.
- Uses of Possessive Pronouns: Beyond Simple ReplacementB1 — The possessive pronouns (le mien, le tien, le sien...) do far more than avoid repetition. They sit at the heart of contrastive emphasis, family idioms (les miens), effort idioms (y mettre du sien), and the toast formula (à la tienne!). This page drills the high-frequency uses that learners rarely meet in textbooks but constantly meet in real French.
- Les Propositions Relatives: Vue d'ensembleB1 — A relative clause attaches a mini-sentence to a noun, sharpening or extending its description. French has a small set of relative pronouns — qui, que, dont, où, lequel — each tied to a specific syntactic role inside the clause. Mastering them unlocks complex sentence-building, and the rules are rigid: French never lets you drop a relative pronoun the way English does.
