The Future Perfect Continuous Tense

The Future Perfect Continuous tense

The future perfect continuous tense is used to show a continued or ongoing action that will start in future and will be continued sometime in future. (Remember, an ongoing action in future which will continue till some time in future). There will be a time reference, such as “since 1980, for three hours” from which the action will start in future and will continue. A sense of time reference is found which gives an idea that action will start at some time in future and will continue for some time.  Such time reference or sense of time reference is the identity of the future perfect continuous tense because it tells that action will start at a particular time in future. For example, “He will have been studying in this school since 2004”, so the it means that he will start studying in this school in 2004 and will study in this school till sometime in future.

Note: If there is not time reference or sense of time reference, it is not the future perfect continuous tense because there is no hint about the time of action when it will start in future and it seems just an ongoing action in future which resembles “future Continuous tense. So the reference of time differentiates between the future perfect continuous tense between future continuous tense.

Rules for using the future perfect continuous tense: 

An auxiliary verb “will have been” is used in sentence. 1st form of the verb +ing (present participle) is used as main verb in sentence. “Since” or “for” is used before the “time reference” in sentence. If the time reference is exactly known such as 1996, 7 O’clock , “since” is used before the time in sentence. If the time reference is not exactly known such as five hours, six years, four days, then “for” is used before the time in sentence. Time reference such as 5 hours or 8 days is not exactly known because we don’t know that about which three hours a day is told in sentence or about which 8 days in a month is told in sentence. While the 1996 is exactly know time.
