The Future Perfect and when to use it

The futur antérieur (future perfect) is used to express a future action or event that will be completed before another future action or to describe a future action or event that will have been completed in the future.

Review: The Passé Composé

  • -ER verbs become é (J'ai dansé)
  • -IR verbs become i (J'ai fini)
  • -RE verbs become u (J'ai vendu)


Verbs that take être stay the same (DR MRS VANDERTRAMP)

  • Example: Je suis parti
  • Tu es descendu
  • Nous sommes arrivés

What do you need to form the Future Perfect?

You need the conjugation of Avoir and Etre in the simple future tense:


  • J'aurai
  • tu auras
  • Il/Elle aura
  • Nous aurons
  • Vous aurez
  • Ils/Elles auront


  • Je serai
  • Tu seras
  • Il/Elle sera
  • Nous serons
  • Vous serez
  • Ils/Elles seront

Formula for Creating the Future Perfect

(subject)(avoir/être conjugation)(passé composé)


  • Tu auras parlé avec moi.
  • Nous serons partis.
  • Elles auront aimé.
  • Vous serez tombés.
  • Elle lui aura parlé demain.
  • Je n'y serai pas allé avant lundi.


The future perfect can make simple assumptions regarding the past


  • Pierre n'est pas ici. Il aura oublié. (Pierre isn't here. He must have forgotten.)
  • Luc est heureux. Il aura gagné .(Luc is happy. He must have won.)


When using conjunctions like quand, lorsque, aussitôt que, dès que, une fois que and après que, the future perfect is used. For example: Nous le ferons aussitôt qu'elle sera arrivée. (We’ll do it as soon as she has arrived.)
