What is the future perfect tense? 

English has a few different ways to talk about future events or actions. The perfect future tense or the future perfect tense is used to connect a future action to another action that is even further in the future. In other words, one future action will be completed before the other future action. 

  • They will have arrived by dinnertime. 
  • By the time I graduate from college I will have moved 8 times. 
  • In December, we will have lived in Mexico for 3 years. 

Sometimes it helps to look at the actions or events on a timeline.

How to use the perfect future tense 

Let’s review how to construct the perfect future tense. The perfect future always includes will, the auxiliary or helping verb have and the past participle of your main verb. The future perfect verb must include have + past participle. The past participle is the main verb. 

Structure: Subject + will + have + past participle. For example: They (subject) will have cooked (past participle). 

The past participle of a regular verb is formed by adding -ed to the end of the infinitive. 

Examples of regular verbs in past participle form.

Cook + ed = cooked

Talk + ed = talked

Jump + ed = jumped
