Future Perfect Progressive Tense

When to use Future Perfect Progressive Tense

Similarly to Future Perfect, Future Perfect Progressive is used to project oneself to the future when he or she will look back to a point in time which is also in the future. However, the focus here is on the continuity of the event that we are looking back to. For example, if you have exams in June and in June, you look back to the time you spent studying, you can say:

I will have been studying for a long time by June.
She will have been training for 10 years next month.
Kate will have been dating William for 20 years this year.

The focus, here, is on the process of studying, not the result of the action.

Structure of Future Perfect Progressive Tense

Subject + will + have + been + Progressive Participle of Main Verb + Object

Future Perfect Progressive combines the perfect and the progressive aspect in the future. It is the most complicated compound verb in the English language, but once you understand how aspects and tenses form a compound verb, it becomes easy to use. Similarly to other future tenses, the auxiliary verb ‘will’ is used to express future and it must be followed by a verb in first form. Therefore, we are going to need the auxiliary verb ‘to have’ to express perfection in present form. The progression is expressed by the auxiliary verb ‘to be’ which must be in past participle form ‘been’ because it follows the auxiliary verb ‘have’. Finally, ‘been’ is followed be the progressive participle (-ing form) of the action verb as in any other progressive tenses.

Some examples for the structure:
Uncle Bob will have been working there for 10 years by May.
I will have been learning English for only a year next week.
