The future perfect tense in French consists of the future of the auxiliary verb avoir or être + the past participle. The past participle follows the same agreement rules as in the passé composé.
|j‘aurai parlé, fini, vendu||nous allons parlé, fini, vendu|
|tu auras parlé, fini, vendu||vous aurez parlé, fini, vendu|
|il/elle/on aura parlé, fini, vendu||ils/elles auront parlé, fini, vendu|
|je serai parti(e), rentré(e), allé(e)||nous serons parti(e)s, rentré(e)s, allé(e)s|
|tu seras parti(e), rentré(e), allé(e)||vous serez parti(e)(s), rentré(e)(s), allé(e)(s)|
|il sera parti, rentré, allé||ils seront partis, rentrés, allés|
|elle sera partie, rentrée, allée||elles seront parties, rentrées, allées|
|on sera parti(s/es), rentré(s/es), allé(s/es)|
The future perfect expresses the idea will have spoken, will have finished, will have sold. In both French and English, the future perfect tense indicates an event that will be completed in the future before another event occurs, or an event that will be completed before some point of time in the future. The simple future tense does not necessarily express the completion of the action – just that it takes place in the future.
The future perfect may appear in main clauses to indicate a future action that will be completed by a certain time.
Ils seront tous partis avant la tombée de la nuit. | They all will have left before nightfall.
The future perfect may appear in subordinate clauses when they are introduced by a conjunction of time indicating that the action of a subordinate clause will be completed before the action of a main clause in the future tense. English uses the present perfect, not the future perfect, in these cases.
On passera le voir quand il se sera levé. | We’ll go by to see him when he has gotten up.
Je te dirai ce qui se passe dès que j’aurai appris quelque chose. | I will tell you what’s going on as soon as I have learned something.
Have an amazing week, everyone!
A la prochaine…
