When do I use à qui and when auquel?

À qui for people, auquel and its forms for things: la femme à qui je parle, le problème auquel je pense. À qui never changes; auquel agrees with the antecedent and gives auquel, à laquelle, auxquels and auxquelles.

Why is it à laquelle and not alaquelle?

Because à only contracts with le and les. The feminine singular article la resists, so à laquelle stays as two words while the masculine and the plurals become auquel, auxquels and auxquelles.

How do I know a verb needs à?

You have to learn it with the verb, because English often hides the preposition. Penser à, répondre à, obéir à, assister à, participer à, s'intéresser à, s'habituer à and s'attendre à are the ones that most often turn up in relative clauses.

What is ce à quoi and when do I need it?

It is the form used when the verb takes à and there is no noun to refer back to: ce à quoi je pense, ce à quoi elle s'attendait. Ce que would be wrong there because the verb does not take a direct object.

Can I say auquel about a person?

Yes, and formal writing does: le témoin auquel on a fait appel. In ordinary French à qui is much more natural for people, and auquel is reserved for things or for administrative style.

À Qui, Auquel, À Laquelle: Relative Pronouns After À in French

Written by Camille Laurent, Lead French Curriculum Editor · Reviewed May 2026

When a relative clause needs the preposition à, French offers two routes: à qui for people, and auquel, à laquelle, auxquels or auxquelles for things. Both keep the preposition at the front of the clause, and which one you use depends only on whether the antecedent is human.

L'ami à qui j'écris habite au Sénégal.

The friend I'm writing to lives in Senegal.

What it is

A great many French verbs take à before their complement: parler à, penser à, répondre à, s'intéresser à, assister à. When that complement becomes the antecedent of a relative clause, the à has to survive, and the pronoun that follows it depends on whether you are talking about a person or a thing.

le projet auquel je travaille — the project I'm working on

How to spot it

Say the clause as a plain sentence first. If you hear an à before the noun, the relative clause will start with à: à qui for a person, auquel or à laquelle for a thing.

la personne à qui j'ai téléphoné — the person I rang
le concours auquel elle s'est inscrite — the competition she entered
la réunion à laquelle nous avons assisté — the meeting we attended
les questions auxquelles il faut répondre — the questions that need answering

There is no version of these sentences with the preposition at the end. La personne que j'ai téléphoné à is impossible in French.

Common À Qui, Auquel, and À Laquelle Examples in French

The à forms with the verbs that require them:

À Qui, for People

La femme à qui tu as demandé l'heure est ma voisine.: The woman you asked the time is my neighbour.
Les élèves à qui j'enseigne ont douze ans.: The pupils I teach are twelve.
Ce sont des gens à qui on peut faire confiance.: They're people you can trust.
Le collègue à qui je dois ce poste part à la retraite.: The colleague I owe this job to is retiring.

À qui does not change for gender or number. One form covers men, women, singular and plural.

Auquel and À Laquelle, for Things

Le sujet auquel il tient le plus est l'éducation.: The subject he cares most about is education.
La proposition à laquelle je m'oppose est mal rédigée.: The proposal I'm opposed to is badly drafted.
L'accident auquel il a échappé était grave.: The accident he escaped was a serious one.
La question à laquelle personne ne répond reste ouverte.: The question nobody answers remains open.

The masculine forms contract with à; the feminine singular keeps its article, giving à laquelle rather than a single word.

The Plurals

Les problèmes auxquels nous faisons face sont nouveaux.: The problems we're facing are new ones.
Les personnes auxquelles j'ai écrit n'ont rien répondu.: The people I wrote to haven't replied.
Les valeurs auxquelles il croit sont simples.: The values he believes in are simple ones.
Les cours auxquels je me suis inscrit commencent lundi.: The classes I've signed up for start on Monday.

Auxquels and auxquelles differ only in the feminine e, and the choice depends entirely on the antecedent.

Ce À Quoi, With No Antecedent

Ce à quoi je pense ne te plaira pas.: What I'm thinking about won't please you.
Ce n'est pas ce à quoi je m'attendais.: That's not what I was expecting.
Voilà ce à quoi il faut faire attention.: That's what you need to watch out for.
Ce à quoi elle aspire, c'est un peu de calme.: What she longs for is a bit of peace.

With no noun to point at, quoi takes over from lequel, and the placeholder ce goes in front.

How the À Forms Work

The verb decides that you need à, and the antecedent decides which pronoun follows it.

The Verb's Preposition Comes First

Before you can choose a pronoun you have to know whether the verb takes à. Répondre à, penser à, s'intéresser à, obéir à and assister à all do; regarder, écouter and attendre do not, and those take a plain que.

La lettre à laquelle je réponds date de janvier.

The letter I'm answering dates from January.

First the verb's preposition, then the pronoun.

Human or Not Decides the Form

For a person, à qui is invariable and idiomatic. For a thing, you need the lequel family, which agrees with the antecedent and contracts with à. This is the one place in the relative system where the person or thing distinction genuinely matters.

L'organisme auquel elle a écrit n'a pas répondu, mais la personne à qui elle a téléphoné a été très aimable.

The organisation she wrote to didn't reply, but the person she rang was very helpful.

Person → à qui, thing → auquel.

Only the Feminine Singular Escapes Contraction

À merges with le and les inside lequel, giving auquel, auxquels and auxquelles. La does not merge, so the feminine singular stays as two words: à laquelle.

La cause à laquelle il consacre son temps est méconnue.

The cause he devotes his time to is little known.

auquel, auxquels, auxquelles — but à laquelle.

Some Verbs Take Lui Instead, So No Relative Is Needed

Verbs whose à introduces a person often take lui and leur as pronouns in a plain sentence: je lui parle. In a relative clause, though, the preposition reappears: la personne à qui je parle. The two facts sit side by side without contradicting each other.

Je lui ai écrit hier ; c'est la collègue à qui j'ai écrit.

I wrote to her yesterday; she's the colleague I wrote to.

lui in a sentence, à qui in a relative clause.

Où Can Replace À Laquelle for Places

If the antecedent is a place, où is lighter and more natural than a form of lequel: la ville où je vais rather than la ville à laquelle je vais. Lequel returns as soon as the antecedent is abstract.

La salle où la conférence a lieu est au premier étage.

The room the conference is being held in is on the first floor.

Place → où, abstraction → auquel.

Common Mistakes with À Qui, Auquel, and À Laquelle

Incorrect: la réunion que j'ai assisté — the meeting I attended

Correct: la réunion à laquelle j'ai assisté — the meeting I attended

Assister takes à, so the relative clause has to keep it. English attend has no preposition, which is what leads to the plain que.

Incorrect: Le concours à lequel il participe est annulé. — The competition he's taking part in has been cancelled.

Correct: Le concours auquel il participe est annulé. — The competition he's taking part in has been cancelled.

À merges with the le inside lequel to give auquel. Only the feminine singular à laquelle keeps the two words apart.

Incorrect: les personnes à quoi j'ai parlé — the people I spoke to

Correct: les personnes à qui j'ai parlé — the people I spoke to

Quoi is for things and only appears when there is no antecedent at all. With a human antecedent the form is à qui, whatever the number.

Incorrect: Ce que je m'attendais était différent. — What I was expecting was different.

Correct: Ce à quoi je m'attendais était différent. — What I was expecting was different.

S'attendre à governs à, so the à has to appear even with no antecedent. Ce que is only for verbs that take a direct object.

Quoi, and the Verbs That Force the Issue

Two things worth memorising: the form used when there is no antecedent, and the verbs that make à unavoidable.

Ce à quoi and prepositions with quoi

When there is no noun to refer back to, lequel is impossible and quoi takes over. With à it gives ce à quoi; the same happens with other prepositions: ce sur quoi, ce en quoi.

Ce à quoi il s'intéresse, c'est la musique baroque.: What he's interested in is baroque music.
Ce sur quoi nous ne sommes pas d'accord est essentiel.: What we disagree on is essential.
Ce en quoi je crois n'a pas changé.: What I believe in hasn't changed.

These are formal. In speech people usually rearrange the sentence: il s'intéresse à la musique baroque, voilà.

The verbs that make à unavoidable

There is no way around learning which verbs govern à. These are the ones that come up most often in relative clauses.

le sujet auquel je pense: the subject I'm thinking of (penser à)
les règles auxquelles il faut obéir: the rules that have to be obeyed (obéir à)
la conférence à laquelle j'ai assisté: the lecture I attended (assister à)
les changements auxquels on s'habitue: the changes you get used to (s'habituer à)

English hides the preposition in several of these — you attend a meeting, you obey a rule — which is exactly why they catch learners out.

À qui for possession in questions and clauses

À qui also asks and states whose, in the sense of belonging. This is not the same as dont, which expresses possession from the other direction.

À qui est ce manteau ?: Whose coat is this?
Je ne sais pas à qui appartient cette voiture.: I don't know whose car this is.
l'enfant à qui appartient ce cartable: the child this schoolbag belongs to

Appartenir à is the verb underneath all three, which is why the preposition is à and not de.
