Lesson 30: Relative pronouns qui, que, où, dont

Part 1: Why relative pronouns exist

They glue two sentences into one by removing a repeated noun. English does this too — and English has a unique freedom French does not allow:

The book that I read was great. The book I read was great. ← English drops the pronoun

French never drops it. The four words qui / que / où / dont are mandatory.

Le livre que j'ai lu était génial. ✓ Le livre j'ai lu était génial. ✗ (impossible in French)

The second English-speaker shock: French does not sort relatives by animacy. English has who (people) vs which/that (things) vs whose (possession). French sorts by grammatical role inside the relative clause — is the shared noun the subject, the direct object, a place/time, or something attached to de? That single question picks the pronoun.

Pronoun	What it replaces	Rough English
qui	subject of the relative clause	who / which / that (doing the action)
que / qu'	direct object of the relative clause	whom / which / that (receiving the action)
où	place or time	where / when
dont	anything attached to de	of which / about which / whose / from which

The diagnostic question: mentally split the sentence in two, find the shared noun, and ask what role it plays in the second sentence. Subject → qui. Direct object → que. Place / time → où. After de → dont.

Part 2: qui — the subject

After qui a verb comes immediately (sometimes with object pronouns in between). The clue is visual: qui + verb, nothing else in front.

C'est l'homme qui parle français. That's the man who speaks French.

Je connais une femme qui habite à Lyon. I know a woman who lives in Lyon.

Les enfants qui jouent dans le parc sont bruyants. The children who are playing in the park are noisy.

Two traps:

• qui never elides before a vowel. l'ami qui arrive, not qu'arrive. (This is the opposite of que, which always elides.)
• The verb agrees with whatever qui refers back to — including je, tu, nous:

Antecedent	Agreement	Example
je / moi	1 sg	C'est moi qui ai raison. (I'm the one who's right)
tu / toi	2 sg	C'est toi qui as choisi. (You're the one who chose)
nous	1 pl	C'est nous qui avons gagné. (We're the ones who won)

English doesn't do this — we say "I'm the one who is right" with the third-person verb. French insists the verb match the real person.

Part 3: que — the direct object

After que, a subject + verb comes next. Before a vowel, que → qu'.

Le film que j'ai vu était génial. The movie (that) I saw was great.

La robe qu'elle porte est belle. The dress (that) she's wearing is beautiful.

Les amis que nous invitons arrivent demain. The friends (whom) we're inviting are arriving tomorrow.

English-speaker's #1 mistake: dropping the pronoun. In English "the movie I saw" is perfectly fine. In French le film j'ai vu is broken. The que is non-negotiable.

The Lesson 24 trap: past participle agreement

When que sits in front of the verb, the direct object is now before the participle. Under avoir, that triggers agreement — the participle takes the gender and number of the antecedent.

Antecedent	Direct object is before the verb	Participle
la robe (f. sg.)	que j'ai achetée	+ e
les livres (m. pl.)	que tu as lus	+ s
les lettres (f. pl.)	que vous avez écrites	+ es
le film (m. sg.)	que nous avons vu	no change

Compare: J'ai acheté la robe. — no agreement (direct object after). La robe que j'ai achetée. — agreement (direct object before).

The -e is silent, the -s is silent — but for verbs whose participle ends in a consonant, the agreement actually changes the sound:

• la lettre que j'ai écrite → "ay-KREET" (t now pronounced)
• les fenêtres que j'ai ouvertes → "oo-VERT" (t now pronounced)

So the agreement is not purely a spelling rule — careful speakers do hear it.

Part 4: où — place and time

Où means "where" and "when". This is the surprise: French uses one word where English uses two. You do not say quand in a relative clause; quand is only a question word or a conjunction ("when X, Y").

Context	French	English
place	La ville où je suis né.	the city where I was born
direction	Le pays où elle va.	the country (to) where she's going
time — day	Le jour où je t'ai rencontré.	the day (when) I met you
time — year	L'année où nous avons déménagé.	the year (when) we moved
time — moment	Au moment où il est entré…	at the moment (when) he came in

Don't say le jour quand je suis né. Wrong. It's le jour où je suis né.

A useful collocation: le jour où, l'année où, l'époque où, le moment où, au moment où — all "the {time} when…".

Part 5: dont — everything attached to de

Dont is the one with no clean English equivalent — it covers "of which", "about which", "from which", "whose", and sometimes "of whom". The trick: it replaces a whole de + noun phrase.

There are three big use cases.

5.1. The verb is built with de

Many French verbs require de before their object: parler de, avoir besoin de, avoir peur de, se souvenir de, rêver de, s'occuper de, dépendre de, se servir de, se moquer de…

When you turn one of those into a relative, de + thing collapses into dont.

Le projet dont je parle est important. The project (that) I'm talking about is important. (← Je parle de ce projet.)

La personne dont tu as peur n'existe pas. The person you're afraid of doesn't exist. (← Tu as peur de cette personne.)

C'est le film dont tout le monde se souvient. That's the film everyone remembers. (← Tout le monde se souvient de ce film.)

English-speaker mental model: if the English sentence ends in a stranded preposition — "talking about", "afraid of", "remember of/about", "depend on" — and that preposition would be de in French, you almost certainly need dont.

5.2. Possession ("whose")

L'homme dont la fille est médecin. The man whose daughter is a doctor. (← La fille de cet homme est médecin.)

Le livre dont l'auteur est célèbre. The book whose author is famous.

After dont in the "whose" sense, French uses the definite article (la fille, l'auteur) — not sa fille or son auteur. English uses "his/her" implicitly through "whose"; French erases it because dont already carries that meaning.

✗ L'homme dont sa fille est médecin. (double marking — wrong) ✓ L'homme dont la fille est médecin.

5.3. Part of a whole

J'ai dix amis, dont trois habitent à Paris. I have ten friends, three of whom live in Paris.

Elle a écrit trois romans, dont un est devenu un best-seller. She's written three novels, one of which became a bestseller.

The structure after dont is always subject + verb (like que), but logically dont extracts a de-phrase.

Trap! Dont does not work after compound prepositions ending in de: à côté de, près de, au sujet de, à cause de, en face de. There you need duquel / de laquelle / desquels / desquelles — that's Lesson 41. ✗ La maison dont je vis à côté. ✓ La maison à côté de laquelle je vis. (L41)
