3. Future Perfect Continuous

Use of the future perfect continuous

Structure [subject + will have been + -ing verb + object]

  1. Describing actions that will continue until a point in the future.
  2. Describing an action that has started, or has not yet started, and will continue in the future.
  3. “By” is also used normally for future events and for the expressions of time. 

The structure is [subject + will have been + ing form + object]

For negative sentences

[ Subject + will not / won’t + have + been + verb (ing)…]

For question sentences

[Will + subject + have + been + verb (ing)…?]

[Won’t + subject + have + been + verb (ing).. ?]

So, as you can see, the future perfect continuous is very similar to the future perfect simple. The main difference is that the future perfect simple normally describes something that will end at a point in the future, while the future perfect continuous will be used to imply that the action will continue in the future.
