Future Tense Questions Medium
The future perfect continuous in the past tense is a verb tense used to describe an ongoing action that was expected to be completed in the past. It is formed by using "would have been" followed by the present participle (-ing form) of the main verb.
For example, if we take the verb "study," the future perfect continuous in the past tense would be "would have been studying." This tense indicates that the action of studying was ongoing and expected to continue until a specific point in the past.
Here is an example sentence: "By the time I arrived at the party, they would have been studying for three hours." This sentence implies that the studying started before the speaker arrived at the party and continued until that point in the past.
