French Relative Clauses: How to Use Qui, Que, Dont, and Où
A clear, practical guide to French relative pronouns: when to use qui, que, dont, and où, with examples and a comparison table.
French relative clauses are the structures that let you connect two ideas into one sentence, the way English uses 'who', 'which', 'that', and 'whose'. Mastering French relative clauses means knowing when to use qui, que, dont, and où, and those four words do not work the same way their English equivalents do. Most learners get qui and que right eventually, but dont trips people up well into B2 level.
What a Relative Clause Actually Does
A relative clause adds information about a noun that was just mentioned. In English: 'The book that I bought is good.' In French: 'Le livre que j'ai acheté est bon.' The word 'that' (or 'which', 'who') is the relative pronoun. It replaces the noun inside the second clause and connects it to the first. French has four main relative pronouns for everyday use: qui, que, dont, and où. Each one fills a specific grammatical role.
Qui vs Que: The Core Distinction
The rule is simple in theory. Qui replaces the subject of the relative clause. Que replaces the direct object. In practice, you identify which role the pronoun is playing inside its own clause.
| Pronoun | Grammatical role | Example |
|---|---|---|
| qui | subject of the relative clause | L'homme qui parle est mon prof. (The man who is speaking is my teacher.) |
| que / qu' | direct object of the relative clause | Le film que j'ai vu était long. (The film that I watched was long.) |
A quick test: look at the verb inside the relative clause. Does the relative pronoun do the action? Use qui. Does something else do the action and the pronoun receives it? Use que. In 'L'homme qui parle', it is the man who speaks, so qui is the subject. In 'Le film que j'ai vu', I did the watching, so the film is the object, and que is correct.
One detail to know: que becomes qu' before a vowel or silent h. Que does not change before a consonant. Qui never contracts, even before a vowel.
Dont: The Pronoun That Replaces de + Noun
Dont is where most learners stall. It replaces a noun preceded by de. That de can appear for several reasons, and once you see the pattern, dont becomes predictable.
- Verbs that take de: avoir besoin de, parler de, se souvenir de, avoir peur de, être fier de
- Nouns followed by de to show possession or relationship: le titre du livre, la couleur de la voiture
- Adjectives followed by de: être content de, être sûr de
Examples: 'C'est le livre dont j'ai besoin.' (That is the book I need. / j'ai besoin du livre.) 'Voici la femme dont je t'ai parlé.' (This is the woman I told you about. / j'ai parlé de la femme.) 'Il a un talent dont il est fier.' (He has a talent he is proud of. / il est fier de son talent.) Each time, dont absorbs the de that would otherwise appear before the noun.
Dont also handles possession. English uses 'whose'. French uses dont. 'J'ai rencontré un auteur dont le roman est célèbre.' (I met an author whose novel is famous.) Notice the word order: dont + subject + verb + rest. This is different from English, and French learners often get the word order wrong. After dont, the subject of the clause comes immediately, before the verb.
Où: Place and Time
Où refers to a place or a point in time. It replaces a location or moment that was just mentioned, functioning as a relative pronoun rather than a question word.
- Place: 'La ville où je suis né s'appelle Lyon.' (The city where I was born is called Lyon.)
- Time: 'Le jour où il est arrivé, tout a changé.' (The day when he arrived, everything changed.)
- Abstract location: 'La situation où nous nous trouvons est difficile.' (The situation we find ourselves in is difficult.)
A common mistake is using que instead of où for location. 'La maison que j'habite' is wrong because habiter does not take a direct object here. The correct form is 'La maison où j'habite', since where you live is a location, not an object.
A Quick Reference Table
| Pronoun | Use it when... | Quick test |
|---|---|---|
| qui | the noun is the subject of the relative clause | Can you say [noun] + verb directly? Use qui. |
| que / qu' | the noun is the direct object of the relative clause | Is there already a subject in the relative clause doing the action? Use que. |
| dont | the noun follows de (verb, adjective, or noun + de) | Would you say 'de + noun' without the relative clause? Use dont. |
| où | the noun is a place or point in time | Can you replace the noun with 'there' or 'at that time'? Use où. |
Word Order Rules to Get Right
Qui and que follow the noun they refer to directly. The clause then continues normally. Dont requires this fixed order: dont + subject + verb + object (if any). Do not put the subject after the verb with dont. 'La personne dont le frère est médecin' is correct. 'La personne dont est médecin le frère' is wrong. Où follows the noun and is then followed by the subject and verb in normal order.
Passé Composé Agreement with Que
When the relative pronoun que is the direct object and the clause uses a passé composé with avoir, the past participle must agree in gender and number with the noun que refers to. 'Les lettres que j'ai écrites.' (Les lettres is feminine plural, so écrites takes an e and an s.) This agreement does not apply to qui, dont, or où.
This is a detail that matters at B2 level and above. If you are working toward TCF or TEF Canada, examiners will look for correct participle agreement. You can find more grammar and vocabulary practice mapped to each proficiency level at Fréquence's lesson library.
Common Mistakes and How to Fix Them
- Using qui instead of dont after verbs that take de. If the verb needs de, use dont, not qui.
- Wrong word order after dont. Always: dont + subject + verb, not dont + verb + subject.
- Using que for locations. If the noun is a place, use où.
- Forgetting participle agreement after que in passé composé. The participle agrees with the noun que refers to.
- Confusing où (relative pronoun) with où (question word). Same spelling, very different function.
How to Practice Relative Clauses
The fastest way to internalize these is to combine pairs of sentences yourself. Take any two French sentences that share a noun and merge them using the correct relative pronoun. Do this with twenty sentences and the logic becomes automatic. Then read French texts and highlight every relative pronoun you find. Identify which role it plays. This is more effective than memorizing lists of rules.
If you are at B1 level and want structured grammar and vocabulary practice, the B1 lesson track on Fréquence covers relative clauses alongside the grammar points that actually move you forward at that level.
FAQ
What is the difference between qui and que in French?
Qui replaces the subject of the relative clause. Que replaces the direct object. If the relative pronoun is doing the action of the verb, use qui. If someone or something else does the action and the pronoun receives it, use que.
When do you use dont in French?
Use dont whenever the noun you are referring to would be preceded by de in the original sentence. This includes verbs like parler de, avoir besoin de, and se souvenir de, as well as possessive relationships like 'the author whose novel' (l'auteur dont le roman).
Can où refer to time in French?
Yes. Où can refer to a specific moment in time, not just a physical place. 'Le soir où nous nous sommes rencontrés' means 'The evening when we met.' In this use, où translates as 'when' rather than 'where'.
Do French relative pronouns change for gender or number?
No. Qui, que, dont, and où do not change form based on the gender or number of the noun they refer to. The only agreement to watch is the past participle in passé composé sentences where que is the direct object preceding the verb.
