What is Future Perfect Tense?

The future perfect tense indicates an action that will be completed between now and some point in the future. Besides, it is also used to express two actions or events of future moments together.

Structure of Future Perfect Tense

The structure of Future Perfect is not completely different from Present Perfect Tense. There is only the difference of auxiliary verbs. The auxiliary verb of this tense is ‘shall have/will have’.

STRUCTURE - Future Perfect Tense

Structure: Shall have/Will have+ past participle form of verb (v.p.p.f)

For example:
I shall have bought this book tomorrow.
He will have submitted his homework next week.

Now look at the negative and interrogative structures:

Negative Structure

Interrogative Structure:

For Example:

Will he have submitted his homework next week?

Two Actions or Events in Future?

Yes, in Future Perfect, there is also the function or structure of two actions or events of future like Past Perfect Tense. If you want to express such double actions in future, you have to express the first action in the structure of Future Perfect Tense and the next action in the structure of Future Indefinite Tense or Present Indefinite Tense. Like before here, you will also use the conjunction ‘before’ or ‘after’ to connect two actions.

So, the structure is:

Future Perfect Tense+ before+ (Future Indefinite Tense/ Present Indefinite Tense)
Or,
(Future Indefinite Tense/Present Indefinite Tense + after+ Future Perfect Tense)

For Example:

You will have examined the book before I will buy it.
(Future Indefinite Tense)

Or,

You will have examined the book before I buy it.
(Present Indefinite Tense)

Or,

I will buy it after you will have examined the book.
