The Future Perfect

The future perfect is a verb form that we use to say something will be finished by a particular time in the future. The verb to have is used in the structure. In this video Tim answers a question about have and if you can use has when the subject is second person singular.

Watch the video and complete the activity


The form of the future perfect is:

subject + will ('ll) + have ('ve) + past participle

There are two auxiliaries (helping words), will and have. Apart from being contracted, they do not change, whatever the subject of the sentence.

This is because will is a modal auxiliary and doesn't have different forms. Modal auxiliaries are followed by the infinitive of the verb without to. In the case of the future perfect the verb is to have and so it will always be have, whatever the subject.

  • I will have finshed by the morning.
  • She'll have finished by the morning.
  • Will you have finished by the morning?
  • They won't have finished by the morning.
