Décontaminer – About the French Futur Antérieur (Future Anterior) Tense

The French futur antérieur tense is a compound tense used to express actions or events that will have occurred in the future before another action takes place. It is formed by using the future tense of the auxiliary verb “avoir” or “être” (depending on the main verb) followed by the past participle of the main verb.
NOTE: To take a deep dive into all the French tenses then see my article on Mastering French Tense Conjugation.

Construction

1. For most verbs, use “avoir” as the auxiliary verb:
   – Subject + future tense of “avoir” + past participle
Example with the verb “manger” (to eat):
– J’aurai mangé (I will have eaten)
– Tu auras mangé (You will have eaten)
– Il/elle/on aura mangé (He/She/One will have eaten)
– Nous aurons mangé (We will have eaten)
– Vous aurez mangé (You will have eaten)
– Ils/elles auront mangé (They will have eaten)
2. For a select group of verbs, use “être” as the auxiliary verb. These are typically verbs of motion or state-changing verbs (e.g., aller, venir, naître, mourir, partir, etc.). The formation is the same, but the auxiliary verb is “être.”
Example with the verb “partir” (to leave):
– Je serai parti(e) (I will have left)
– Tu seras parti(e) (You will have left)
– Il/elle/on sera parti(e) (He/She/One will have left)
– Nous serons parti(e)s (We will have left)
– Vous serez parti(e)(s) (You will have left)
– Ils/elles seront parti(e)s (They will have left)

Common Everyday Usage Patterns

   – Je partirai dès que j’aurai fini mon travail. (I will leave as soon as I have finished my work.)
   – Ils seront rentrés avant que la pluie commence. (They will have returned before the rain starts.)
2. It is often used with time expressions that indicate when the action will occur relative to another future action, such as “dès que” (as soon as), “avant que” (before), “une fois que” (once), etc.

Interactions with Other Tenses

– The futur antérieur tense is commonly used in combination with the future simple (futur simple) and other tenses to indicate the sequence of actions in the future. The futur antérieur typically refers to the action that will have been completed before another action takes place.

For example

– Quand tu auras terminé ton devoir, tu pourras sortir. (When you have finished your homework, you can go out.)
