Advanced French Relative Pronouns: Mastering "Dont" and "Lequel" for CLB 10

Introduction: The C1 Syntactic Frontier

In the Expression Écrite and Expression Orale subtests of the TEF (Test d'Évaluation de Français) and TCF (Test de Connaissance du Français), examiners are specifically listening for Syntactic Complexity (La complexité syntaxique).

While Qui and Que are the "bread and butter" of B1 French, the pronouns Dont and Lequel (and its variations Auquel, Duquel) are the markers of a C1 or C2 level (NCLC 9/10). These pronouns allow you to combine multiple ideas into a single, elegant sentence—a hallmark of advanced fluency.

In this 2000-word guide, we’ll show you exactly how to master Dont and Lequel for your exam at prepmyfrench.com.

Section 1: The Mystery of "Dont"

Dont is used to replace a noun preceded by the preposition de. It is the most common "Advanced" pronoun in French.

The Three Main Uses of "Dont"

1. Possession: C’est un sujet DONT l’importance est capitale. (It's a subject whose importance is paramount.)
2. Verb + DE: Le projet DONT je vous parle... (The project I'm talking about... - From parler de).
3. Adjective + DE: Le résultat DONT je suis fier... (The result I'm proud of... - From être fier de).

Pro-Tip: Use Dont to start your TEF Writing Section B. "La problématique DONT il est question ici..." immediately signals to the examiner that you are a C1 speaker.

Section 2: The Versatility of "Lequel"

Lequel is used after a preposition (other than de, which uses dont). It must agree in gender and number with the noun it replaces (Laquelle, Lesquels, Lesquelles).

The "Prep + Lequel" Pattern

• Avec: L’entreprise AVEC LAQUELLE je collabore. (The company with which I collaborate.)
• Pour: Le but POUR LEQUEL nous luttons. (The goal for which we are fighting.)
• Dans: La situation DANS LAQUELLE nous nous trouvons. (The situation in which we find ourselves.)

Section 3: The "Auquel" and "Duquel" Contractions

When Lequel follows the prepositions à or de, it contracts:

• À + Lequel: Auquel / À laquelle / Auxquels.
• De + Lequel: Duquel / De laquelle / Desquels.

The "Expert" Structure: Use these for complex relations. "C'est un défi AUQUEL nous devons faire face." (It's a challenge we must face.)

Section 4: Why "Dont" and "Lequel" are CLB 10 Markers

Examiners have a "Syntactic Range" checklist. If they only hear Qui and Que, you are limited to a B2 score. If they hear Dont and Auquel correctly used, they automatically move you into the C1 descriptor.

At prepmyfrench.com, our AI Writing Grader Specifically highlights your "Syntactic Depth." It shows you exactly where you could have used a relative pronoun to combine two short, choppy sentences into one professional C1 sentence.
