You’re about to make past possibilities, regrets, and cautious claims come alive in French. Learn to build the conditionnel passé, then step straight into its meaning in your first sentences.

The past conditional places an action in the past, but without presenting it as a realized fact. It is used for an imagined action, possible at another time, or prevented by another situation.

The form distances the action and shows that it belongs to the realm of the unaccomplished.
