The future perfect tense is used to describe actions that will be completed before a specified time in the future. It is formed using "will have" plus the past participle of the main verb. Some examples of its uses include: 1) Describing actions that will finish before a stated future time, such as "He will have delivered all the newspapers by 8 o'clock." 2) Expressing times before or until a future time using words like "by", "before", or "until". 3) Denoting actions that will begin in the past, continue up until a moment in the future, and be ongoing, such as "Louisa will have been a teacher for 20 years by next May
