Identify the primary use of the future perfect tense.

The primary use of the future perfect tense is to describe events that will have been completed before a certain point in the future. This tense is constructed using "will have" followed by the past participle of the verb. Its function is to emphasize the completion of an action in relation to a future timeline. For example, in the sentence "By next year, I will have graduated," the future perfect tense indicates that the action of graduating will be completed before a specific point in the future (next year).

This tense is particularly useful for establishing clear expectations about future events and helps to create a timeline of actions related to future outcomes. It reflects the idea of looking ahead and determining what will be finished at or before a certain moment in time.
