Future Perfect Continuous Tense describes ongoing actions that will be completed at some point in the future. In this blog post, we’ll discuss when and how to use this tense with some examples.
What is the Future Perfect Continuous Tense?
The future perfect continuous tense describes an action that will be ongoing for some time in the future and will end before a certain point. This tense is formed using the future perfect tense (will have) + been + the present participle of the main verb (verb + -ing).
For example, “By the next year, Mona will have been working in this company for four years.” In this example of future perfect continuous tense, the action of working started at some point in the past. It is still ongoing and will be completed by a specific time.
This tense highlights how long an action will last before it finishes. It does not matter when the action began—what’s important is that it will be ongoing for a while and end before another future event or time.
