Advanced Grammar – Future Perfect Revision

Hey, everyone!

Are you all ready to brush up on some important grammar? I bet you are so let’s go!

The Future Perfect is a slightly difficult tense in English but it is important to learn how to use it correctly.

Firstly, the Future Perfect tense is used to express the idea that something will happen before another action in the future.


She will have done her homework by the time Claire arrives.

It also shows that something will happen by a certain time in the future.


Kevin and I will have left by the time you get to the party.

The Future Perfect

We form the Future Perfect using “will have” + a past participle.

To form negative sentences, we use “will not have” (or “won’t have”) + a past participle.

Look at the following dialogue between Carol (C) and John (J) to see how it’s used:

C: I can’t believe that by April this year we will have been to twenty different countries.

J: I know. It’s crazy! We will have done so many different things and I’m sure we will have

  met loads of new people too.

C: Will we have learnt any new languages by then?

J: No, I don’t think we will have learnt any new languages; we’re too lazy!

C: Speak for yourself!

As you can see in the above dialogue, the speakers are referring to a future time, in this case “April”, and they are discussing all the different things they will or might have done by that time.

To form questions in the Future Perfect, we place the auxiliary will at the front of the sentence, followed by the subject + have + a past participle.


Will we have learnt any new languages by then?
