Le Subjonctif, a key aspect of French grammar, expresses doubt, uncertainty, desires, or subjective opinions. It is used after certain expressions or verbs convey these notions, indicating a hypothetical or uncertain action. Unlike the indicative mood, which deals with facts, the subjunctive addresses possibilities and emotions. Its conjugation patterns vary across tenses and persons. Mastery of the French subjunctive is crucial for conveying subtleties and depth in French communication.

What is Le Subjonctif/Subjunctive? 

In French, the subjunctive mood expresses subjective ideas, possibilities, feelings, doubts, and uncertainties. Unlike the indicative mood, which deals with facts and certainties, the subjunctive mood navigates the realm of the hypothetical and emotional.

Its primary functions include:

Expressing Wishes and Desires: The subjunctive conveys desires or wishes that may or may not come true.Example: “Je souhaite que tu réussisses.” (I hope you succeed.)

Conveying Uncertainty or Doubt: It expresses uncertainty or doubt about a situation.

Example: “Je doute qu’il vienne.” (I doubt he will come.)

Reflecting Emotions or Opinions: The subjunctive mood is utilized to express emotions or opinions, emphasizing the subjective nature of the statement.

Example: “Il est triste que tu partes.” (It’s sad that you’re leaving.)

Following Certain Conjunctions: Certain conjunctions trigger the use of the subjunctive mood, particularly when they introduce clauses expressing doubt, desire, or possibility.

Example: “Bien que je sache la vérité, je reste silencieux.” (Even though I know the truth, I remain silent.)

In summary, the subjunctive mood in French adds depth and nuance to language by allowing speakers to articulate subjective ideas, feelings, doubts, and possibilities, contributing to richer and more expressive communication.

When to Use the Subjunctive in French 

In French, the subjunctive mood is commonly used in subordinate clauses introduced by the conjunction “que” (that). These subordinate clauses often express subjective ideas, desires, doubts, or possibilities. Here are some key contexts where the subjunctive is employed in subordinate clauses starting with “que”:

Expressions of Wishes and Desires:

Example: Je veux que tu viennes. (I want you to come.)

Expressions of Doubt and Uncertainty:

Example: Je doute qu’il soit là. (I doubt he is there.)

Expressions of Emotion and Opinion:

Example: Il est important que vous soyez présents. (It’s important that you be present.)

Expressions of Necessity and Obligation:

Example: Il est nécessaire que nous partions. (It’s necessary that we leave.)

Expressions of Prohibition and Interdiction:

Example: Il est interdit que vous fumiez ici. (It’s forbidden for you to smoke here.)

Expressions of Impersonality:

Example: Il est possible que je sois en retard. (It’s possible that I am late.)

Expressions of Probability and Hypothetical Situations:

Example: Il est peu probable que nous gagnions. (It’s unlikely that we will win.)

Expressions of Opinion or Judgment:

Example: Il est bon que tu aies réussi. (It’s good that you have succeeded.)

Expressions of Fear, Hope, or Worry:

Example: J’ai peur qu’il neige demain. (I’m afraid it will snow tomorrow.)

Expressions of Permission or Prohibition:

Example: Je permets que vous utilisiez mon ordinateur. (I allow you to use my computer.)

In all these cases, the subjunctive mood is used to convey the subjective, uncertain, or hypothetical nature of the subordinate clause introduced by “que”. Mastering the subjunctive in these contexts allows for more nuanced and expressive communication in French.

Here are some common phrases and conjunctions that often trigger the usage of the subjunctive mood in French:

Irregular Verbs and Exceptions:

While regular verbs follow a predictable pattern in the subjunctive mood, irregular verbs and exceptions require memorization due to their unique conjugation patterns. Here are some examples of irregular verbs in the subjunctive mood:

  1. Être (to be):
    • Que je sois (that I be)

    • Que nous fassions (that we do/make)
    • Que vous fassiez (that you do/make)
    • Qu’ils/elles fassent (that they do/make)

These irregular verbs have unique conjugations in the subjunctive mood, which must be memorized to use them accurately in French sentences. Practice and exposure to these irregular forms will help reinforce their usage.

Agreement of the Participe Passé 

In French, the past participle can agree in gender and number with the subject or direct object under certain conditions. Here’s an explanation of when and how this agreement occurs, along with special cases and exceptions:

Agreement with the Subject:

When the auxiliary verb is “être” (to be), the past participle agrees in gender and number with the subject.

  • Example: Elle est arrivée. (She arrived.)
  • Example: Ils sont arrivés. (They arrived.)

However, when the auxiliary verb is “avoir” (to have), the past participle generally does not agree with the subject, except in certain cases (see exceptions below).

Agreement with the Direct Object:

When the direct object precedes the verb and is placed before the past participle, the past participle agrees in gender and number with the direct object.

  • Example: Les pommes que j’ai mangées étaient délicieuses. (The apples that I ate were delicious.) [agreement with “pommes” (feminine, plural)]
  • Example: Le gâteau qu’il a mangé était délicieux. (The cake that he ate was delicious.) [no agreement because “gâteau” is masculine and singular]

Special Cases and Exceptions:

When the auxiliary verb is “avoir” and the direct object is placed after the verb, the past participle does not agree with the direct object.

  • Example: J’ai mangé les pommes. (I ate the apples.)

However, in literary or formal language, agreement with the direct object after “avoir” may occur, especially when the direct object is a pronoun.

  • Example: Les pommes que j’ai mangées. (The apples that I ate.)

Common Pitfalls and Mistakes

Here are some common errors and misconceptions related to subjunctive usage in French:

Overuse of the Subjunctive: Learners sometimes use the subjunctive mood excessively, especially when expressing desires or wishes that are statements of fact. It is important to recognize when the indicative mood is more appropriate.

Incorrect Conjugation: Conjugating verbs incorrectly in the subjunctive mood is a common mistake. This can include using the wrong stem or mixing up endings, particularly with irregular verbs.

Misunderstanding Trigger Phrases: Some learners struggle to recognize when to use the subjunctive based on trigger phrases or expressions. This can lead to inappropriate mood selection in sentences.

Misplacement of Subjunctive Clauses: Placing the subjunctive clause incorrectly within a sentence can alter its intended meaning. Learners should ensure proper positioning of the subjunctive clause about the main verb.

Here are some common instances where the indicative mood is mistakenly used instead of the subjunctive:

Statements of Fact: The indicative mood expresses facts, certainties, or habitual actions. However, learners sometimes use the indicative instead of the subjunctive after expressions of doubt, uncertainty, or emotion. 

For example:

Incorrect: Je suis sûr que tu vas réussir. (I’m sure that you will succeed.)

Correct: Je doute que tu réussisses. (I doubt that you will succeed.)

Expressions of Necessity or Demand: Verbs expressing necessity, obligation, or demand often require the subjunctive mood. Using the indicative instead can lead to incorrect interpretation:

Incorrect: Il est nécessaire que tu viens maintenant. (It’s necessary that you come now.)

Correct: Il est nécessaire que tu viennes maintenant. (It’s necessary that you come now.)

Wishes and Desires: When expressing wishes, desires, or hopes, the subjunctive conveys uncertainty or unreality. Using the indicative in such cases can lead to confusion:

Incorrect: Je veux que tu viens avec moi. (I want you to come with me.)

Correct: Je veux que tu viennes avec moi. (I want you to come with me.)

Uncertain Conditions: Conditional clauses expressing uncertainty or hypothetical situations require the subjunctive mood. Using the indicative instead can change the meaning:

Incorrect: Si tu es là, je suis content. (If you are here, I am happy.)

Correct: Si tu étais là, je serais content. (If you were here, I would be happy.)

Frequently Asked Questions

Q: What is the difference between subjunctive and infinitive in French?

Subjunctive Mood:

The subjunctive mood expresses uncertainty, doubt, desire, emotion, or hypothetical situations. It is often triggered by certain expressions or verbs that convey these notions. The subjunctive mood has different conjugation patterns depending on tense and person.

Example: Il faut que tu viennes (It is necessary that you come).

Infinitive:

The infinitive form of a verb is the unconjugated form that expresses the action or state without reference to a specific subject. It is often used after modal verbs, certain expressions, or as the complement of other verbs. The infinitive form remains unchanged regardless of the subject or tense.

Example: Je veux venir avec toi (I want to come with you).

Q: When not to use subjunctive in French?

In French, the subjunctive mood is not used in certain situations where the indicative mood or other constructions are more appropriate:

Statements of Fact: The subjunctive mood is used to express uncertainty, doubt, or desire, so it is not used to state facts or certainties. In such cases, the indicative mood is used instead.

Example: Il est certain qu’il viendra demain. (It is certain that he will come tomorrow.)

Direct Commands: Direct commands or requests generally do not require the subjunctive mood. Instead, the imperative mood is used for direct commands.

Example: Viens ici! (Come here!)

After Certain Conjunctions: Some conjunctions, such as après que (after), lorsque (when), and dès que (as soon as), do not require the subjunctive mood when referring to actions that have already occurred or are viewed as certain.

Example: Il partira dès qu’il aura fini son travail. (He will leave as soon as he finishes his work.)

Expressions of Certainty: Expressions of certainty or knowledge do not take the subjunctive mood. Instead, the indicative mood is used.

Example: Je sais qu’il est à la maison. (I know that he is at home.)

Certain Modal Verbs: Modal verbs such as pouvoir (can), devoir (must), and savoir (to know) do not trigger the subjunctive mood.

Example: Je peux venir demain. (I can come tomorrow.)
