Qui vs Que: The Subject/Object Relative Pronouns

The two relative pronouns qui and que are the workhorses of French syntax. Together they introduce the vast majority of relative clauses you will read, hear, write, and speak. The distinction between them is purely grammatical — not about meaning, not about animacy, not about register. Qui is used when the relative pronoun functions as the subject of its clause; que is used when it functions as the direct object. That is the entire rule.

For an English speaker, the difficulty is that English uses who, whom, that, and which with a different logic — based on animacy (who for people, which for things) crossed with case (who for subject, whom for object). French ignores animacy entirely: qui and que apply equally to people, things, animals, and abstractions. What matters is the syntactic role inside the clause.

This page presents the rule, gives you a reliable test for picking qui vs que, drills the contrast extensively, and addresses the most common errors. By the end you should be able to produce relative clauses spontaneously and recognize them effortlessly in reading.

The rule, stated as cleanly as possible

A relative clause is a mini-sentence attached to a noun (called the antecedent), modifying that noun. The relative pronoun is the link between the antecedent and the mini-sentence. Inside the mini-sentence, the relative pronoun has a grammatical role:

• If the relative pronoun is the subject (the doer) of the verb in the clause, use qui.
• If the relative pronoun is the direct object (the receiver of the action), use que.

That is the whole rule.

In qui parle, the qui is the subject of parle. The man speaks. L'homme parle. Replace l'homme with qui in subject position → qui parle.

In que je vois, the que is the direct object of vois. Je vois l'homme. Replace l'homme with que in object position → que je vois.

The tip-off: after qui, you typically see a verb directly. After que, you typically see a subject pronoun (je, tu, il, elle, on, nous, vous, ils, elles) or a noun subject, then a verb.

The reconstruction test

When you are unsure which one to write, reconstruct the clause as a complete sentence by putting the antecedent back into the relative clause. Then ask: where did it go? Subject? Object?

Test 1: L'homme [il / lui] parle. Where does l'homme fit? In subject position: l'homme parle. The man is the subject. → L'homme *qui parle.*

Test 2: L'homme [je le vois]. Where does l'homme fit? As direct object of vois: je vois l'homme. The man is the object. → L'homme *que je vois.*

Test 3: Le livre [il est sur la table]. Subject of est: le livre est sur la table. → Le livre *qui est sur la table.*

Test 4: Le livre [je le lis]. Object of lis: je lis le livre. → Le livre *que je lis.*

This test works every time. It is mechanical and never fails.

Drill: qui — relative pronoun as subject

The most common pattern is noun + qui + verb. Note that the verb in the relative clause agrees with the antecedent, since the qui inherits the antecedent's person and number.

Notice that in c'est elle qui chante and c'est nous qui venons, the verb agrees with the subject of the cleft (elle, nous), not with qui. This is the standard rule: the relative qui takes its agreement from its antecedent. So c'est moi qui suis, c'est toi qui es, c'est lui qui est, c'est nous qui sommes, c'est vous qui êtes, c'est elles qui sont.

A crucial detail: qui does not elide. Even before a vowel, it stays qui. Qui arrive stays qui arrive; never qu'arrive. This contrast with que (which does elide) is one of the most reliable spotters in real French texts.

Drill: que — relative pronoun as direct object

The pattern is noun + que + subject + verb. The clause has its own subject (je, tu, Marie, les enfants), and que is the direct object of the verb. Because the object is fronted (it precedes the verb), French has a special agreement rule for compound tenses (see below).

Notice the elision in qu'elle écrit. Que elides to qu' before a vowel or mute h. This is mandatory: qu'il, qu'elle, qu'on, qu'Anne, qu'avec, qu'hier. The unelided form que il / que elle / que on is ungrammatical.

Past-participle agreement after que (the famous rule)

When the verb in the relative clause is in a compound tense with avoir (passé composé, plus-que-parfait, etc.) and que is the direct object preceding the verb, the past participle agrees in gender and number with the antecedent (the noun that que refers back to).

The participle écrite agrees with feminine singular la lettre. Spelled écrite (with -e), pronounced /ekʁit/ (the t becomes audible).

The participle lus agrees with masculine plural les livres. Pronounced like lu (the s is silent), but the spelling matters.

The participle achetées agrees with feminine plural les fleurs.

The participle prise agrees with feminine singular la décision. (The verb aie is subjunctive — triggered by the superlative + relative; see verbs/subjunctive/triggers/superlative-relative.)

This rule applies only when the direct object precedes the verb. If the object follows, no agreement: j'ai lu les livres (no agreement on lu) versus les livres que j'ai lus (agreement). The que construction always triggers agreement because que is necessarily a fronted direct object.

You cannot drop the relative pronoun

In English, you can drop the relative pronoun when it is the object: the book I read, the man I saw. In French, you cannot. Que is mandatory.

This is the single most common error among English speakers. Internalize it: in French, every relative clause begins with a relative pronoun. There is no zero-relative.

Animacy doesn't matter

Where English splits who (people) from which / that (things), French does not. Qui and que are chosen purely by syntactic role — subject or object — regardless of whether the antecedent is a person, an animal, an object, or an abstraction.

This animacy-blindness is one of the cleanest aspects of French grammar — once you stop trying to ask who or which?, the choice gets simpler.

When neither qui nor que is right

Some relative clauses do not use qui or que — they use dont, où, or a preposition + qui / lequel. Here is a quick map; the details belong to other pages.

• dont — when the relative replaces de + noun: l'homme dont je parle (the man I'm talking about — parler de). See pronouns/relative/dont.
• où — when the relative is a place or time: la ville où j'habite, le jour où je suis arrivé.
• à qui / avec qui / pour qui — when the relative is the object of a preposition (other than de) and the antecedent is a person: l'ami à qui je pense.
• lequel / laquelle / lesquels / lesquelles — same role as à qui etc., with antecedent person OR thing, used after most prepositions: le livre auquel je pense, la chaise sur laquelle je suis assis.

The cleanest decision tree:

1. If the relative is the subject of its clause → qui.
2. If it is the direct object → que.
3. If it is the object of de → dont.
4. If it indicates place or time → où.
5. If it is the object of any other preposition → preposition + qui (people) or preposition + lequel (things or people).

This page is about steps 1 and 2. The other steps have their own pages.

High-frequency clefts: c'est ... qui / c'est ... que

The cleft construction c'est X qui / c'est X que is built on these same relative pronouns. The cleft picks an element out and emphasizes it.

The same rule applies: qui if the clefted element is the subject of the embedded verb; que if it is the object (or other non-subject role). For more on clefting, see syntax/clefting-c-est-que.

Common Mistakes

You must include the relative pronoun. English drops that / which; French never does.

The reconstruction test: l'homme parle — subject. → qui.

The reconstruction: je lis le livre — object. → que.

Qui never elides, even before a vowel. Only que elides (to qu').

After que (preceding direct object), the past participle agrees with the antecedent in compound tenses with avoir.

In c'est moi qui, the verb agrees with moi (first person). C'est moi qui suis, c'est toi qui es, c'est lui qui est, c'est nous qui sommes, c'est vous qui êtes, c'est eux qui sont. This is the standard qui agreement rule.

When the relative clause has its own subject (here je) and the antecedent is the object of the verb, use que.

Always run the reconstruction test. If the antecedent ends up as subject in the rebuilt sentence → qui. If as object → que.

Key Takeaways

• Qui = subject of the relative clause. Que = direct object.
• The choice has nothing to do with animacy. Qui and que apply equally to people, things, animals, abstractions.
• Qui never elides. Que elides to qu' before a vowel.
• The relative pronoun is mandatory — French does not allow the English-style zero relative (the book I read must be le livre que je lis).
• After que (a fronted direct object), the past participle in compound tenses with avoir agrees with the antecedent in gender and number.
• The reconstruction test — put the antecedent back into the clause and see whether it lands in subject or object position — is foolproof. Use it whenever you are unsure.
• For other relative roles, see dont (replacing de + noun), où (place/time), and preposition + qui / lequel (other prepositional roles).
