The future perfect tense is used to express an action that will be completed or finished at a specific point in the future before another action or time reference occurs. It describes an event that will have happened by a certain time in the future.
The future perfect tense is formed by using the auxiliary verb “will have” followed by the past participle of the main verb. The basic structure is “will have + past participle” (e.g., “I will have finished,” “They will have arrived“).
Key points to take away with you:
- Completion in the Future: It emphasizes the completion of an action before a specific point or event in the future.
- Example: “By the time she arrives, I will have completed the project.“
- Time References: It often uses time expressions such as “by,” “by the time,” “by the year,” to indicate the point in the future when the action will be completed.
- Example: “By next Monday, I will have written the report.”
- Cause-and-Effect Relationship: It shows the cause-and-effect relationship between two future actions, with the future perfect action being the one that happens first.
