We use the future perfect tense to talk about something that will have been completed by a certain time in the future. It is often used with a time expression detailing a time in the future.
It follows a general formula of will + have + verb (past participle).
We include the word not between will and have for negative sentences.
For questions or interrogative form, we switch the subject and will.
For example: I will have finished this book by Friday.
She will have cooked dinner by 7 o'clock.
They will have left by the time I arrive.
She will not have finished by the time the assignment is due. Will she have finished the race by tomorrow?
