Relative pronouns: ce qui, dont, où, lequel

Relative pronouns are the parts that weld two sentences into one. The basic four — how qui / que / où / dont divide the work — are covered on Other Pronouns. This page is the layer above: referring back to a whole clause, what to do when the verb carries its own preposition, and how far dont's job actually extends. That is where B1+ writers lose the most points.

Look at the antecedent first

Choosing a relative pronoun takes two steps, and the first one is not "person or thing":

That last row is what this page is about: when the antecedent is not a noun but everything you just said, you have to insert a ce first.

🔴 ce qui / ce que: pointing back at a whole clause

English "…, which let me…" / "…, which I really like" cannot be translated with a bare qui / que, and it should not become a separate sentence with cela either. The French is , ce qui / , ce que.

Once the ce is in place, the qui/que choice works exactly as before — look at what the clause is missing:

• missing subject → ce qui: Nous parlions anglais, ce qui m'a permis de progresser.
• missing direct object → ce que: Je fais du yoga depuis un an, ce que j'aime beaucoup.
• verb takes de → ce dont: J'ai trouvé ce dont j'avais besoin.
• verb takes à → ce à quoi: C'est ce à quoi je pensais.

Every line below is a sentence a learner actually wrote:

💡 Worth marks in writing: , ce qui is the cheapest way to fuse two short sentences into one complex one. Three clipped sentences in a row cost you; one join fixes them.

In first position it is a set pattern, always followed by c'est:

• Ce qui compte, c'est de trouver un équilibre.
• Ce que je préfère, c'est la liberté.
• Ce dont j'ai le plus envie, c'est de partir.

tout ce qui / tout ce que

"Everything that…" is tout ce qui / tout ce que — the ce cannot be dropped:

• tout ce qui est nécessaire (everything necessary) — clause missing its subject
• tout ce que je recherche (everything I'm looking for) — clause missing its object
• ❌ tous ce qui s'est passé → ✅ tout ce qui s'est passé

⚠️ This tout is neuter singular — not tous. For people it is a different phrase entirely: tous ceux qui — Je le recommande à tous ceux qui veulent progresser.

dont: it replaces one thing, a de

dont stands in for the de that follows a verb or a noun, and nothing else:

• parler de qch → le sujet dont je parle
• avoir besoin de qch → quelque chose dont vous avez besoin
• la manière de faire → la manière dont il travaille
• possession: un pays dont la capitale est Paris (whose capital is Paris)

🔴 In our correction data dont is overused more often than it is avoided. One sentence came back eight times from different writers: ❌ au bord de la mer dont la vue change selon l'heure ✅ au bord de la mer, où la vue change selon l'heure The test is blunt: if the clause says where something happens, it is où. Only when a real de has been swallowed does dont apply.

⚠️ dont is followed by normal word order (subject + verb), and no son / sa / leur may reappear — dont already absorbed that de:

• ✅ un pays dont la capitale est Paris　❌ un pays dont sa capitale est Paris

où: place, and time too

où is not only "where". Time nouns take it as well — English "when" is où in French:

• le jour où je suis arrivé (the day I arrived) · l'année où il est né · au moment où je suis sorti
• ❌ le jour quand je suis arrivé

The looser "in which it happened" sense belongs to où too: une expérience où j'ai appris à collaborer · une annonce où vous proposez un service.

⚠️ ou and où are two different words: ou = or (no accent), où = where / when (with the ù). Mixing them up is the single most frequent error on this page — more than every lequel variant put together. Proofread for it: no accent only where "or" would fit.

Preposition + qui / lequel

This is the section that shows your level, and the one our data flags hardest: the verb carries its own preposition and the writer used que anyway.

• participer à qch → les événements auxquels j'ai participé
• assister à qch → un concert auquel j'ai assisté
• faire face à qch → les maladies auxquelles ils doivent faire face
• set phrase: la raison pour laquelle… (the reason why…)

Whether the antecedent is a person or a thing decides qui vs lequel:

à and de contract with lequel:

Only à / de + lequel contract. The feminine singular laquelle does not — write à laquelle / de laquelle. ⚠️ The spelling is laquelle, not "lequelle". Learn "la raison pour laquelle" as one block.

💡 dont or duquel: a verb taking de directly gets dont; a de buried inside a prepositional phrase (à côté de / près de / au sujet de) gets duquel — la maison à côté de laquelle j'habite.

celui / celle / ceux / celles

The celui family must be followed by something: -ci / -là, de, or a relative clause. It never stands bare.

• celui de Pierre (Pierre's one) · ceux des écoles publiques
• ceux qui veulent progresser (the ones who want to improve) · celui que tu préfères

🔴 The classic slip is using ce where celui belongs: ❌ Je le recommande à tous ce qui veulent　✅ à tous ceux qui veulent The test: people or a specific thing → celui family; a whole situation → ce.

It earns its keep in comparisons, where it saves you repeating the noun:

• les enseignants des écoles privées sont plus stricts que ceux des écoles publiques

Classic traps ⚠️

One line to remember

Look at the antecedent: a noun → pick qui / que / dont / où by what the clause is missing; a whole preceding clause → put a ce in front; a verb with its own preposition → preposition + qui (people) / lequel (things), contracting à and de into auquel / duquel; and for people use ceux, never ce.
