Looking for sufficient definitions and explanations of this tense, I noticed that one meaning will usually refer to something someone "will have done" as something that "will have been done\completed". While I do realize this is one independent reason to use this tense, I don't quite get a lot by a definition of a tense which uses the tense it attempts to define. It would really help me if someone could clarify the subject, including regarding similar forms, such as: Will Have: gone, finished, completed, ended...All(Or most V3 verbs).
Will have done has two meanings:
- used for saying that you expect an action to be completed before a time in the future. We will have gone to bed by the time you arrive.
- supposition about what happened Example: He will probably have noticed that his bike is broken. It is called wine,' said O'Brien with a faint smile. 'You will have read about it in books, no doubt.(1984).
