PE-40: Future Perfect and Future Perfect Continuous

By this time next year, what will you have done? Standing in the future and looking back — will have + V3, and will have been + -ing.

PE-40: Future Perfect and Future Perfect Continuous

Here is a strange and rather beautiful thing English can do: it can put you in the future and let you look backwards from there. "By June I will have finished school." June has not arrived, and neither has the finishing — yet you are already standing in June, looking back at a completed action. These are the last two tenses of the Perfect family.

In this lesson you will learn

  • will have + V3 — finished before a future moment
  • will have been + verb-ing — how long, up to a future moment
  • The signal word by, and the by the time rule
  • How these two complete the whole tense system
Finished before a future point Subject + will have + V3
subject — ega verb — kesim object — toʻldiruvchi helper verb — yordamchi feʼl

1. The picture: standing in the future, looking back

I finish school
PastNowFuture

The blue dot is the action; the red dot further right is the future moment you are looking back from. Everything is ahead of NOW — the action just happens earlier than the deadline.

By next June I will have finished school.

Kelasi iyunga qadar maktabni tugatgan boʻlaman.

Oʻzbekcha Future Perfect oʻzbekchadagi "...gan boʻlaman" shakliga toʻgʻri keladi: tugatgan boʻlamanI will have finished. Uni tanish qilib turadigan soʻz — by ("...gacha, ...ga qadar"): by Friday, by next year, by the time you arrive.

2. The signal word: by

This tense almost always appears with by or by the time, because it needs a deadline to look back from.

1by + a time

I'll have read it by Friday.

2by then

Come at six — I'll have cooked by then.

3by the time + clause

By the time you arrive, we'll have eaten.

4in / before

In two years he'll have graduated.

Rule After by the time, use the Present Simple — never will. This is the time-clause rule from PE-26 again: By the time you arrive, we will have finished.

By the time the guests get here, Afsona will have made the plov.

Mehmonlar yetib kelguncha, Afsona palovni pishirib boʻlgan boʻladi.

Two futures in one sentence, but only one will.

3. Future Perfect Continuous — how long, by then

Add been + -ing and you get duration instead of completion: not "what will be finished", but "how long it will have been going on".

Duration up to a future point Subject + will have been + verb + ing

Next month I will have been studying English for six years.

Kelasi oyda ingliz tilini oʻrganayotganimga olti yil boʻladi.

The studying continues; we are only measuring it from a future point.

will have + V3 — completed

  • By 2030 he will have built the house.
  • I will have written ten pages by Friday.

will have been + -ing — duration

  • By 2030 he will have been building it for five years.
  • By Friday I will have been writing for a week.
Oʻzbekcha Farq PE-37 dagi bilan bir xil, faqat kelajakda: will have + V3 — ish tugagan boʻladi ("yozib boʻlgan boʻlaman"). will have been + -ing — ish qancha vaqtdan beri davom etayotgani ("yozayotganimga bir hafta boʻladi"). Ikkinchisi kamroq ishlatiladi, lekin imtihonlarda uchraydi.
Oʻzbekcha PE-31 dagi by va until farqi shu yerda ish beradi: bu zamon faqat by bilan ishlatiladi, chunki u muddat talab qiladi. By Friday I will have finished ✓ ("jumagacha tugatgan boʻlaman"), until Friday I will have finished ✗. Until davom etadigan ish uchun: I will wait until Friday.

4. Form details

  1. Same for everyone: I / she / they will have finished.
  2. Negative: They won't have arrived by six.
  3. Question: Will you have finished by then?
  4. Short answer: Yes, I will. / No, I won't.
Teacher's tip The Future Perfect is also the polite way to guess about the present: "You will have heard the news by now, I expect." It means "I assume you already know". You will meet this idea again in the modals of deduction, PE-47.

5. Common mistakes

By the time you will arrive, we will have eaten.

By the time you arrive, we will have eaten.
