Perfect passive tense, Pluperfect passive tense and Future perfect tense

We build passive verb forms in the present perfect tense by placing has/have + before the past participle form of the verb.

Changing the'-m' ending of the supine to'-s' to form the past participle to form the perfect passive, pluperfect passive and future perfect passive tense. Note that in gender, number and case, a past participle must align with the word it switches and it decreases like 'bonus, -a, -um' .

So, now we know that future perfect tense verbs will include + have + verb will (ending in -ed). Again, there is something they're saying it will be in the future. But, the "something" is going to stop. For starters, "By Saturday, you will have worked ten hours."
