The Future Perfect Tense

I. The Formation

The Future Perfect is formed by means of the auxiliary verb ''to have'' in the Future Indefinite and Participle II of the notional verb.

  • He will have spoken.

  • Will he have spoken?

  • He will not have spoken.

II. The Use

1) The Future Perfect is used to denote an action that begins before a certain moment of time in the future and goes up to that moment or into it. We use the tense to make predictions about actions which we expect to be completed by a particular time in the future. Compare:

Note 1: The following time indications can be used: before, by the time, by then, till/until (only in negative sentences)

  • He won't have repaired my camera till the end of this week.
