How to Use Compound Modal Verbs in French

Compound modal verbs are an essential part of English grammar, but they don't exist in the same form in French. Understanding how to express these concepts in French is crucial for effective communication.

Let's explore the French equivalents of compound modal verbs and how to use them correctly.

Could Have

In French, "could have" is typically expressed using the verb pouvoir in the conditional perfect tense.

1. He could have been right. - Il aurait pu avoir raison.
2. We could have won the game. - Nous aurions pu gagner le match.
3. You could have called me. - Tu aurais pu m'appeler.

May Have and Might Have

Both "may have" and "might have" are translated in French using peut-être with a past tense or il se peut que followed by the past subjunctive.

2. They might have arrived already. - Il se peut qu'ils soient déjà arrivés.
