Unit 3 · Lesson 2 of 6

Lequel, auquel, duquel

Lequel at full strength: all twelve forms with à and de glued on, the long list of French verbs that take à even when English uses no to (participer à, assister à, s'abonner à, faire face à), qui or lequel for people, preposition + quoi when there is no noun (ce à quoi), and lequel as the question word which one.

Key things to remember

  1. 1Forms: lequel, laquelle, lesquels, lesquelles; with à: auquel, à laquelle, auxquels, auxquelles; with de: duquel, de laquelle, desquels, desquelles.
  2. 2The French verb decides the preposition, even when English has none: assister à, participer à, faire face à, s'abonner à, s'attendre à, tenir à → la réunion à laquelle j'ai assisté.
  3. 3People after a preposition: usually qui (à qui, avec qui); lequel is also correct but more formal, and needed after parmi (parmi lesquels). Things: lequel, not qui.
  4. 4No noun to agree with (ce, quelque chose, rien, a whole idea): preposition + quoi: ce à quoi je m'attendais.
  5. 5Question which one?: Lequel / Laquelle / Lesquels / Lesquelles (des…) ?, agreeing with the noun; Auquel… ? Duquel… ? merge too.

Read a formal letter, a film review or a news editorial in French and you will meet sentences like C'est la raison pour laquelle je ne viendrai pas (That is the reason why I will not come) and Voici les journaux auxquels je suis abonné (Here are the newspapers I subscribe to). In Grade 11 you learned that French moves the preposition to the front of a relative clause and follows it with lequel for things. At Grade 12 the difficulty is no longer the idea; it is spotting the preposition. English often hides it (the meeting I attended, the challenges we face), while French verbs carry it openly (assister à, faire face à). Once you can see it, you need the right one of twelve forms. This lesson gives you that, plus the formal uses of lequel for people, quoi when there is no noun, and the question Lequel… ?

À and de merge with the le or les at the front of lequel exactly as they merge with the article (au, aux, du, des). The feminine singular laquelle never merges: à laquelle, de laquelle.

The à-verbs: where auquel hides

The trap is that English translates many à-verbs with no preposition, or with a different one: to attend = assister à, to face = faire face à, to take part in = participer à, to think about = penser à. If you translate word for word you will write la réunion que j'ai assistée, which is wrong because assister needs à. Always rebuild the clause as a full French sentence first (j'ai assisté à la réunion), and the preposition shows itself.

French verbRelative clauseEnglish
être abonné àles journaux auxquels je suis abonnéthe newspapers I subscribe to
participer àle projet auquel je participethe project I'm taking part in
assister àla conférence à laquelle nous avons assistéthe lecture we attended
faire face àles défis auxquels la région fait facethe challenges the region is facing
penser à / réfléchir àla solution à laquelle j'ai penséthe solution I thought of
s'intéresser àles enjeux auxquels je m'intéressethe issues I'm interested in
s'habituer àle climat auquel je me suis habituéthe climate I got used to
tenir àle chandail auquel je tiens le plusthe sweater I care about most
s'attendre àle résultat auquel on s'attendaitthe result we expected
grâce à (compound)la bourse grâce à laquelle j'ai pu étudierthe scholarship thanks to which I was able to study
Each verb keeps its à in the relative clause. The form of lequel agrees with the noun before it: journaux is masculine plural, so auxquels; conférence is feminine singular, so à laquelle.
Three steps for any preposition
1. Rebuild the second idea as a full French sentence and find the preposition: La région fait face à ces défis. 2. Check the noun being replaced: défis is masculine plural, and it is a thing. 3. Front the preposition + the matching form, merging à or de: auxquels. Result: les défis auxquels la région fait face. The same steps give pour laquelle (pour + la raison), sans lesquels (sans + les outils), sur lequel (sur + le sujet). One more check: these forms are indirect objects, so a past participle with avoir after them does not agree with them: les réunions auxquelles j'ai assisté (not assistées), unlike les réunions que j'ai organisées.
APreposition + qui (the usual choice for people)
  • la conseillère à qui j'ai écrit — the advisor I wrote to
  • les amis avec qui je pars à Gaspé — the friends I'm going to Gaspé with
  • l'entraîneur grâce à qui j'ai progressé — the coach thanks to whom I improved
BPreposition + lequel for people (formal or needed)
  • la conseillère à laquelle j'ai écrit — same meaning, more formal
  • les candidats parmi lesquels on choisira — the candidates among whom we will choose (parmi: lesquels, not qui)
  • J'ai rencontré le frère de ma voisine, laquelle habite à Sudbury. — I met my neighbour's brother; she (the neighbour) lives in Sudbury.

The last example shows a formal use you will see in reports and legal or news writing: lequel as a subject after a comma, chosen because its gender points to the right noun. Qui habite à Sudbury could describe the brother or the neighbour; laquelle can only mean the neighbour. In everyday speech and writing, plain qui is the normal subject pronoun; use subject lequel only when it removes a real ambiguity. For things, modern French does not use qui after a preposition (only literary writing does, for a personified thing): la bourse grâce à laquelle, not grâce à qui.

No noun to agree with? Use quoi
Lequel needs a noun to agree with. When the thing is vague (ce, quelque chose, rien) or is a whole idea, French uses preposition + quoi: C'est exactement ce à quoi je m'attendais (That's exactly what I expected; s'attendre à). Il y a quelque chose à quoi tu n'as pas pensé (There's something you haven't thought of). Ce sur quoi je veux insister, c'est la sécurité (What I want to stress is safety; insister sur). After ce, quoi is the only option; after quelque chose you will also see auquel (quelque chose auquel je n'avais pas pensé). This is the preposition version of the ce qui / ce que / ce dont family you know from Grade 11.

Lequel in questions: which one?

QuestionEnglishWhy this form
Lequel des personnages trouves-tu le plus convaincant ?Which of the characters do you find most convincing?personnage: masculine singular
Laquelle des possibilités te semble la plus réaliste ?Which of the options seems most realistic to you?possibilité: feminine singular
Auquel de ces programmes t'es-tu inscrit ?Which of these programs did you sign up for?s'inscrire à + programme
Duquel parles-tu ?Which one are you talking about?parler de + a masculine noun
Avec lesquelles de tes amies pars-tu ?Which of your friends are you leaving with?avec + amies: feminine plural
Ces romans, lesquels as-tu lus ?These novels, which ones have you read?lesquels is a direct object before avoir, so lus agrees
Interrogative lequel replaces quel plus a noun already mentioned or about to be named with de. It agrees with that noun and merges with à and de just like the relative pronoun.
Quel or lequel?
Quel is an adjective: it needs a noun (Quel film as-tu choisi ? Which film did you choose?) or être (Quelle est ta réponse ?). Lequel is a pronoun: it stands in place of the noun (Lequel as-tu choisi ? Which one did you choose?) and is the form you need before de: Lequel des films, never quel des films.

Find what the shared noun does in the second sentence, follow the chart to qui, que, dont, où or a form of lequel, and watch lequel agree and merge with à and de.

In context: an application for a summer immersion program

  • Je vous écris au sujet du programme d'immersion auquel je souhaite participer cet été. — I am writing about the immersion program I wish to take part in this summer.
  • C'est un programme auquel je pense depuis deux ans, et la raison pour laquelle il m'attire est simple. — It's a program I have been thinking about for two years, and the reason it appeals to me is simple.
  • Les activités culturelles auxquelles j'ai assisté à Ottawa m'ont donné envie de vivre en français. — The cultural events I attended in Ottawa made me want to live in French.
  • Ce à quoi je tiens le plus, c'est de parler français tous les jours. — What matters most to me is speaking French every day.
  • Je joins une lettre de ma conseillère, grâce à qui j'ai découvert ce programme. — I am enclosing a letter from my advisor, thanks to whom I discovered this program.

Where marks get lost

  • Dropping a preposition English doesn't show: le projet que je participe, la réunion que j'ai assistée. Rebuild the French verb: participer à → auquel je participe; assister à → à laquelle j'ai assisté.
  • Building impossible forms: à lequel, auquelle, à lesquels, de lesquelles. À and de merge with le/les only: auquel, à laquelle, auxquels, desquelles.
  • Using qui for a thing after a preposition: la bourse grâce à qui. For things: grâce à laquelle.
  • Making the participle agree with auxquelles: les conférences auxquelles j'ai assistées. Indirect object → assisté.
  • Writing quel des films or ce que je m'attendais. Use lequel des films and ce à quoi je m'attendais.
