The future perfect continuous tense is used to describe a continuous action that will be ongoing, continuously progressing, and completed at a specific time in the future.
The future perfect continuous tense is formed by using the auxiliary verb “will have been” followed by the present participle (-ing form) of the main verb.
The basic structure is “will have been + verb-ing” (e.g., “By next year, I will have been working here for five years”).
- “By the time they arrive, I will have been waiting for three hours.“
- “In July, she will have been studying French for two years.“
- “By the end of the week, they will have been traveling for a month.“
In these examples, the future perfect continuous tense emphasizes the duration and ongoing nature of the action leading up to a specific time in the future.
