French Sequence of Tenses (Concordance des Temps): Rules and Examples

The French sequence of tenses (la concordance des temps) is a fundamental grammatical concept governing how verb tenses in a main clause interact with verb tenses in subordinate clauses. Whether you are reporting speech, describing past events, or making hypothetical statements, mastering tense agreement is essential for achieving fluency at the intermediate and advanced levels (B1–C2).

This comprehensive guide breaks down the rules of tense agreement in the indicative mood, conditional clauses, and modern subjunctive usage.

1. The Core Principle: Three Time Relationships

Whenever a sentence contains a main clause (proposition principale) and a subordinate clause (proposition subordonnée), the action in the subordinate clause relates to the main action in one of three ways:

1. Simultaneity (simultanéité): The secondary action happens at the same time as the main action.

2. Anteriority (antériorité): The secondary action happened before the main action.

3. Posteriority (postériorité): The secondary action will happen after the main action.

Which tense you select depends on whether the main verb is in a present/future tense or a past tense.

2. When the Main Verb Is in the Present or Future

When the main verb is in the present indicative (présent) or simple future (futur simple), tense sequence feels natural and aligns closely with English grammar.

3. When the Main Verb Is in the Past (The Golden Rule)

Time Relationship Subordinate Tense Example
:--- :--- :---
Simultaneity (same time) Present (Présent) Je sais qu'elle habite à Paris. (I know that she lives in Paris.)
Anteriority (earlier event) Passé Composé or Imparfait Je pense qu'il a réussi son examen. (I think he passed his exam.)
Posteriority (later event) Simple Future (Futur simple) J'espère que tu viendras demain. (I hope you will come tomorrow.)

This is where many French learners encounter difficulties. When the main clause verb is conjugated in a past tense—such as the passé composé, imparfait, or passé simple—the subordinate verb shifts further into the past.

A. Simultaneity: Use the Imparfait

  • Direct speech: « Je suis occupé. » (I am busy.)
  • Reported past speech: Il a dit qu'il était occupé. (He said he was busy.)
  • Example: Elle croyait que nous dormions. (She thought that we were sleeping.)

    • If the subordinate action was happening at the exact moment of the past main action, use the imparfait (not the present):

    B. Anteriority: Use the Plus-que-parfait

  • Example: Marc m'a expliqué qu'il avait perdu ses clés. (Marc explained to me that he had lost his keys.)
  • Here, losing the keys happened before Marc explained the situation.

    • If the subordinate action occurred prior to the past main action, use the plus-que-parfait (pluperfect):

    C. Posteriority: Use the Conditionnel Présent (Future in the Past)

  • Direct speech: « J'arriverai à huit heures. »
  • Reported speech: Il a affirmé qu'il arriverait à huit heures. (He stated that he would arrive at eight o'clock.)
  • Example: Nous savions que le projet réussirait. (We knew that the project would succeed.)

    • When expressing an action that was in the future relative to a past event, use the conditional present (conditionnel présent) as the future in the past (le futur dans le passé):

    5. Sequence of Tenses with "Si" Clauses (Conditionals)

    Main Clause Verb Simultaneity Anteriority Posteriority
    :--- :--- :--- :---
    Present / Future Présent Passé composé / Imparfait Futur simple
    Past (Passé composé, Imparfait) Imparfait Plus-que-parfait Conditionnel présent

Conditional sentences (les propositions avec si) follow a rigid sequence of tenses. Remember: never place a future or conditional verb directly after the conditional si.

1. Real or probable conditions:

  • Pattern: Si + Présent -> Futur Simple
  • Example: Si tu étudies régulièrement, tu réussiras ton examen. (If you study regularly, you will pass your exam.)

2. Hypothetical conditions in the present (unreal present):

  • Pattern: Si + Imparfait -> Conditionnel Présent
  • Example: Si j'avais plus de temps libre, j'apprendrais le piano. (If I had more free time, I would learn piano.)

3. Unreal conditions in the past (regrets):

  • Pattern: Si + Plus-que-parfait -> Conditionnel Passé
  • Example: Si vous étiez partis à l'heure, vous n'auriez pas raté le vol. (If you had left on time, you wouldn't have missed the flight.)

    • 6. The Subjunctive Sequence: Modern vs. Classical French

In classical French literature, past main clauses demanded the imparfait du subjonctif or plus-que-parfait du subjonctif (e.g., Il fallait qu'il vînt).

  • Use Subjonctif Présent for simultaneous or future subordinate events: Il a fallu que je parte. (I had to leave.)
  • Use Subjonctif Passé for anterior events: Je suis content que tu aies pu venir. (I am glad that you were able to come.)

    • However, in modern conversational and formal French, this rule has evolved:

You only need to recognize the literary subjunctive forms when reading classic French novels or historic texts.

7. Common Pitfalls to Avoid

  • Mixing future with past reported speech: Avoid saying « Il a dit qu'il viendra ». Always use the conditional: « Il a dit qu'il viendrait ».
  • Putting conditionnel after "si": Never say « Si j'aurais su ». The correct structure is « Si j'avais su ».
  • Forgetting time markers: When switching to indirect speech in the past, time references shift accordingly (demain becomes le lendemain, hier becomes la veille, aujourd'hui becomes ce jour-là).

By practicing these structures in writing and spoken conversation, you will produce precise, natural, and grammatically impeccable French.
