15.3 Expressing necessity, desire, and doubt

The subjunctive mood in French is crucial for expressing necessity, desire, and doubt. It's used with specific verbs and expressions to convey hypothetical or uncertain situations, adding nuance to your communication.

Understanding when to use the subjunctive versus the indicative is key. The subjunctive highlights subjectivity and uncertainty, while the indicative states facts. Mastering this distinction will greatly improve your French language skills.

Necessity and Obligation

Using the Subjunctive to Express Necessity and Obligation

• The subjunctive mood conveys necessity, obligation, and other hypothetical or uncertain situations in French
• Specific conjunctions, verbs, and expressions trigger the subjunctive when they express necessity or obligation
  • "il faut que" (it is necessary that)
  • "il est nécessaire que" (it is necessary that)
  • "il est important que" (it is important that)
• The subjunctive emphasizes the imperative nature of the action or situation being described

Forming the Subjunctive for Regular and Irregular Verbs

• Subjunctive forms derive from the third-person plural present indicative form, with exceptions for irregular verbs
• Regular -er verbs form the subjunctive stem by dropping the -ent ending from the third-person plural present indicative form
• Regular -ir and -re verbs use the same subjunctive stem as the third-person plural present indicative form
• Common irregular subjunctive forms include:
  • "être" (sois, sois, soit, soyons, soyez, soient)
  • "avoir" (aie, aies, ait, ayons, ayez, aient)
  • "aller" (aille, ailles, aille, allions, alliez, aillent)
  • "faire" (fasse, fasses, fasse, fassions, fassiez, fassent)

Desire and Preference

Expressing Desire, Preference, and Wish with the Subjunctive

• The subjunctive mood expresses desire, preference, and wish in French, following certain verbs and expressions
  • "vouloir que" (to want that)
  • "préférer que" (to prefer that)
  • "souhaiter que" (to wish that)
  • "espérer que" (to hope that)
• When the main clause and dependent clause have different subjects, the subjunctive is required in the dependent clause
  • "Je veux que tu viennes." (I want you to come.)
• When the main and dependent clauses share the same subject, the infinitive is used instead of the subjunctive
  • "Je veux venir." (I want to come.)

Impersonal Expressions of Desire and Preference

• Impersonal expressions conveying desire or preference also trigger the subjunctive
  • "il est souhaitable que" (it is desirable that)
  • "il est préférable que" (it is preferable that)
• These expressions emphasize the speaker's personal feelings or opinions about the action or situation
• The subjunctive highlights the hypothetical or uncertain nature of the desired outcome

Doubt and Uncertainty

Using the Subjunctive to Express Doubt and Uncertainty

• The subjunctive mood communicates doubt, uncertainty, and subjectivity in French, often following specific verbs and expressions
  • "douter que" (to doubt that)
  • "ne pas croire que" (to not believe that)
  • "il est possible que" (it is possible that)
  • "il se peut que" (it may be that)
• Negative or interrogative expressions that convey doubt or uncertainty trigger the subjunctive
  • "je ne pense pas que" (I don't think that)
  • "croyez-vous que" (do you believe that)

Impersonal Expressions of Doubt and Subjectivity

• Impersonal expressions conveying doubt, uncertainty, or subjectivity trigger the subjunctive in the dependent clause
  • "il est douteux que" (it is doubtful that)
  • "il n'est pas certain que" (it is not certain that)
• The subjunctive expresses opinions, emotions, and judgments that are subjective in nature
  • "je suis content(e) que" (I am happy that)
  • "je regrette que" (I regret that)
  • "il est dommage que" (it is a pity that)

Indicative vs Subjunctive

Differentiating Between Indicative and Subjunctive Moods

• The indicative mood expresses facts, certainties, and objective statements
• The subjunctive mood expresses opinions, emotions, doubts, and hypothetical situations
• When expressing opinions and emotions, the indicative mood is used for statements the speaker considers certain or factual
  • "Je sais qu'il est intelligent." (I know that he is intelligent.)
• The subjunctive mood is used for opinions and emotions that are subjective, doubtful, or uncertain
  • "Je ne pense pas qu'il soit intelligent." (I don't think that he is intelligent.)

Context-Dependent Use of Indicative and Subjunctive

• Some verbs and expressions can be followed by either the indicative or subjunctive mood, depending on the context and the speaker's level of certainty
  • "Je crois qu'il est là." (I believe that he is here. - indicative)
  • "Je ne crois pas qu'il soit là." (I don't believe that he is here. - subjunctive)
• Certain impersonal expressions always trigger the subjunctive, regardless of the level of certainty
  • "il est important que" (it is important that)
  • "il est nécessaire que" (it is necessary that)
  • "il est dommage que" (it is a pity that)
