Understanding the Future Perfect Tense
The future perfect tense is used to describe an action that will have been completed before another action or a specific time in the future. It is formed using the auxiliary verbs “will have” followed by the past participle of the main verb.

– **Past participle**: The third form of the verb, often ending in -ed for regular verbs (finished, completed) and varying forms for irregular verbs (left, done).
Examples:
– I will have traveled to five countries by the end of the year.
