Future Perfect and Future Perfect Continuous

1. We use the Future Perfect to talk about something that will be completed by (not later than) a certain time in the future. When we use this structure, we think of future time and look back from that future time to say that something will be complete.

I’ll have finished dinner by 8.00.

“I’ll phone you at 11.00.” “No, I’ll have gone to bed by then. Can you phone earlier?”

I’ll have worked here for a year next September.

Next year is Ted and Amy’s 25^th wedding anniversary. They will have been married for 25 years.

We’re late. I expect the film will have already started by the time we get to the cinema.

2. The Future Perfect Continuous describes a continuous action (very often one which is already in progress) which will finish by a certain point in the future:

In ten minutes we’ll have been waiting for this bus for exactly an hour!

Amer will have been studying English for ten months by the time he goes back to Syria in October.
