Modal Verbs in French: Devoir, Falloir, Pouvoir, Vouloir

This lesson focuses on essential French modal verbs used to express obligation, permission, or desire. Modal verbs are an integral part of everyday communication and always are followed by an infinitive verb. Understanding how to use these verbs correctly will help you describe what you must do, can do, want to do, or need to do.

Key Modal Verbs Covered

  • Vouloir – to want
    Example: Je veux goûter ce fromage. (I want to taste this cheese.)
  • Devoir – to have to, must
    Example: Je dois peser les ingrédients. (I must weigh the ingredients.)
  • Pouvoir – to be able to, can
    Example: Je peux cuisiner avec toi ? (Can I cook with you?)
  • Falloir – to be necessary (impersonal)
    Example: Il faut goûter avant de choisir. (It is necessary to taste before choosing.)

What You Will Learn

Modal verbs are conjugated before an infinitive verb to express:

  • Obligation: Like devoir (must, have to)
  • Permission or ability: Like pouvoir (can, be able to)
  • Desire or intention: Like vouloir (want)
  • Necessity: Using falloir, which is impersonal and only conjugated in the third person singular.

Important Notes on Usage

The verb falloir is unique as it is always used impersonally and conjugated only as il faut. This means you do not say "je faut" or "tu faut." Instead, it expresses a general necessity or obligation.

Differences Between English and French Modal Verbs

Unlike English, modal verbs in French are placed directly before an infinitive verb without additional auxiliary verbs. For example, English uses "have to" or "can," while French uses just "devoir" or "pouvoir" plus the infinitive. Another difference is that "falloir" has no direct personal subject like "I" or "you," but uses the impersonal "il" instead, translating roughly as "it is necessary."
