Future perfect tense equals shallwill plus have plus?

Answer 1

All perfect tenses involve a past participle and a form of the verb have. This form is specified by the tense's name. The present perfect would use has or have, the past perfect uses had, and the future perfect uses the future form will have and at times shall have.

Once the form of have has been determined, it is joined with the past participle of the verb to be conjugated. For example, the past participle of eat is eaten, dance's is danced, talk with talked, buy with bought, etc.
