Désulfurer – About the French Subjonctif Présent (Subjunctive Present) Tense

The French Subjonctif Présent, often referred to simply as the “subjunctive mood,” is a verb tense used to express doubt, uncertainty, subjectivity, and emotions. It is not used to describe actions or facts that are considered certain or objective. Here, I will explain the Subjonctif Présent tense, its common everyday usage patterns, and how it interacts with other tenses in French.
NOTE: To take a deep dive into all the French tenses then see my article on Mastering French Tense Conjugation.

Formation of the Subjonctif Présent

To form the Subjonctif Présent tense for regular verbs, you typically follow these rules

1. Start with the third-person plural (ils/elles) form of the present tense of the verb.
2. Remove the -ent ending.
3. Add the appropriate endings for each verb group:
   – For -er verbs: e, es, e, ions, iez, ent.
   – For -ir verbs: e, es, e, issions, issiez, issent.
   – For -re verbs: e, es, e, ions, iez, ent.

Common Everyday Usage Patterns

1. Expressing Uncertainty and Doubt. The Subjonctif Présent is commonly used to express uncertainty, doubt, or subjective feelings. For example:
   – Je doute qu’il vienne. (I doubt he is coming.)
   – Il est possible que nous ayons des problèmes. (It is possible that we will have problems.)

2. Emotions and Desires. You use the subjunctive to express emotions, desires, hopes, and wishes.
   – Je veux que tu sois heureux. (I want you to be happy.)
   – J’aimerais que vous veniez à la fête. (I would like you to come to the party.)

3. Impersonal Expressions. Some impersonal expressions require the Subjonctif Présent, such as “il est important que” (it is important that), “il est nécessaire que” (it is necessary that), or “il faut que” (it is necessary that).
   – Il est nécessaire que nous partions. (It is necessary that we leave.)

4. Expressions of Possibility and Hypothesis. Subjunctive can be used to express possibilities and hypotheses:
   – Si j’étais riche, je voyagerais. (If I were rich, I would travel.)

Interactions with Other Tenses

The Subjonctif Présent can interact with other tenses in various ways:

1. Present Subjunctive with Present Indicative. Often, the Subjonctif Présent is used alongside the present indicative to express a contrast between certainty and uncertainty. For example:
   – Il est sûr que tu viens. (It’s certain that you are coming.)
   – Il est possible que tu viennes. (It’s possible that you are coming.)

2. Past Subjunctive with Past Indicative. The Subjonctif Passé is used in conjunction with past indicative tenses to express doubt, uncertainty, or emotion about past actions or events.
   – J’étais triste qu’il soit parti. (I was sad that he had left.)

3. Future Subjunctive with Future Indicative. The Subjonctif Futur can be used with future indicative tenses to express doubt or uncertainty about future actions.
   – J’espère qu’il viendra. (I hope he will come.)

4. Conditional and Subjunctive. The Subjonctif Présent is often used with the conditional mood to express hypothetical or unreal situations.
   – Si j’avais de l’argent, je voyagerais. (If I had money, I would travel.)
