Introduction to Noun Clauses

French grammar consists of various elements that work together to create meaning and structure in the language. One of these elements is the noun clause, a group of words that act as a noun in a sentence. Noun clauses are essential for understanding complex sentences, as they provide additional information to help clarify the meaning of the main clause.

Defining a Noun Clause

A noun clause is a group of words that contains a subject and a verb, functioning as a noun within a sentence. It can act as the subject, object, or complement of a sentence, and often provides essential information to clarify the meaning of the main clause.

Noun clauses help create more complex sentences by embedding additional information within the sentence structure. This allows for greater flexibility and richness in expressing ideas and thoughts, making the language more engaging and nuanced.

Types of Noun Clauses

There are three main types of noun clauses in French:

Subject Noun Clauses

A subject noun clause functions as the subject of a sentence, providing the main focus of the action. It often begins with a conjunction, such as “que” (that), or an interrogative pronoun or adverb, like “qui” (who) or “comment” (how).

Que tu aimes les fraises est évident.
(“That you like strawberries” is obvious.)

Object Noun Clauses

An object noun clause acts as the direct or indirect object of a verb, providing more information about the action being performed. It often follows verbs like “penser” (to think), “dire” (to say), or “savoir” (to know), and may also begin with a conjunction or interrogative pronoun or adverb.

Je pense qu’elle viendra demain.
(I think “that she will come tomorrow.”)

Appositive Noun Clauses

An appositive noun clause provides additional information about a noun or pronoun in the main clause, often functioning as a parenthetical explanation. These clauses usually begin with a relative pronoun like “qui” (who) or “que” (that).

L’idée qu’elle a proposée est intéressante.
(The idea “that she proposed” is interesting.)

Formation of Noun Clauses

There are several ways to form noun clauses in French:

Conjunctions and Relative Pronouns

One common way to create noun clauses is by using conjunctions like “que” (that) or “si” (if), or relative pronouns like “qui” (who) or “lequel” (which).

Il est probable que nous partirons en vacances.
(It is likely “that we will go on vacation.”)

Interrogative Pronouns and Adverbs

Another way to form noun clauses is by using interrogative pronouns like “qui” (who), “quoi” (what), or “lequel” (which), or interrogative adverbs like “où” (where), “quand” (when), or “comment” (how).

Je ne sais pas où il a mis mes clés.
(I don’t know “where he put my keys.”)

Pronoun “ce” and Infinitive Verbs

Noun clauses can also be formed using the pronoun “ce” (this) followed by an infinitive verb, which adds emphasis or specificity to the action.

Ce quitter était difficile.
(“Leaving” was difficult.)

Using Noun Clauses in Sentences

Noun clauses can be used in various ways within a sentence, depending on their function and the information they provide. Here are some examples of how to use noun clauses effectively:

  • As subjects: Que tu sois heureux me rend heureux. (“That you are happy” makes me happy.)
  • As direct objects: Elle veut qu’on l’aide. (She wants “us to help her.”)
  • As indirect objects: Ils parlent de ce qu’ils ont vu. (They talk about “what they saw.”)
  • As complements: Je suis sûr qu’elle réussira. (I am sure “that she will succeed.”)
  • As appositives: Le film qu’elle a choisi est excellent. (The movie “that she chose” is excellent.)

Common Errors and Pitfalls

When dealing with noun clauses in French, it is essential to be aware of some common errors and pitfalls that can lead to confusion or incorrect usage:

  • Misusing conjunctions: Be sure to use the appropriate conjunction or relative pronoun to create a noun clause, as each one has a specific function and meaning.
  • Agreement issues: Ensure that the subject and verb within the noun clause agree in number and gender, as this can affect the overall meaning of the sentence.
  • Incomplete clauses: It is crucial to include both a subject and a verb within the noun clause, as omitting one or the other can lead to an incomplete and unclear sentence.
  • Misplacing clauses: Make sure to place the noun clause in the appropriate position within the sentence, as this can affect its function and meaning.

Practice Exercises

To test your understanding of noun clauses in French, try the following exercises:

  1. Identify the noun clauses in the following sentences and determine their function (subject, object, or appositive): a. Je ne sais pas qui a mangé le gâteau.
    b. Que tu aies réussi m’étonne.
    c. Le livre que j’ai acheté est passionnant.
  2. Rewrite the sentences using a noun clause instead of a simple noun: a. J’adore les fraises.
    b. Il a trouvé la clé.
    c. Elle a accepté l’invitation.
  3. Correct any errors in the following sentences: a. Je pense que tu es contente.
    b. Ils ont dit qu’ils viendront.
    c. J’ignore ce qu’elle a dit.


Mastering noun clauses in French is an essential step towards understanding and using the language effectively. By learning the various types, formations, and functions of noun clauses, you can create more complex and engaging sentences, expressing your thoughts and ideas with precision and nuance. With practice and patience, you will soon become a confident and proficient French speaker.
