Future-perfect tense verbs express actions that will have occurred or conditions that will have been at a specific time in the future.  They can also express actions that will have occurred or conditions that will have been before another future action or condition.

            The future perfect tense is created with the auxiliary verbs

         will have plus a past participle.                   .

               Raul will have lived in Wisconsin for ten years when he moves back to

                        Kentucky.
