FUTURE PERFECT

A. FORMATION- The future perfect (futur antérieur) is formed with the future tense of the auxiliary AVOIR or ETRE and the past participle of the main verb. Agreement rules, word order, and negative/interrogative patterns are the same as for the passé compose.

B. USAGE- the future perfect is used to express an action that will have taken place before another action in the future. It expresses the English will have + past particle

1. Use the future perfect with quand, lorsque, aussitôt que, dès que, and après que if that action will have taken place before another future action.

            Ex. 1 Dès qu’il auro trouvé un emploi, il achètera une voiture.

            (As soon as he has found (will have found) a job, he will buy a car.)

            Ex.2 Partons aussitôt qu’il aura appelé.

            (Let’s leave as soon as he has called (will have called).)

2. At times, it is up to the speaker to decide whether to use the simple future or the future perfect after one of the above conjuctions.  When both clauses are in the simple future, it is implied that both action took place at the same time.

            Ex.1 Aussitôt qu’il achètera sa nouvelle voiture, il nous emmènera fair un tour.

            (As soon as he buys his new car, he will take us for a ride.)

            Ex.2 Aussitôt qu’il aura acheté sa nouvelle voiture, il nous emmènera fair un tour.

(As soon as he has bought (will have bought) his new car, he will take us for a ride.)

3. After the conjuction après que, the future perfect is used when that action takes place in the future.

            Ex.1 Après que nous serons revenus, je te raconterai toutes nos aventures.

            (After we (will) have returned, I will tell you about all our adventures.)
