In present perfect we are using has/have in structures, and in future perfect we use only have why?
why we are not taking Has with will?
I am confused badly.................
on your clarification i will be obliged forever
After modal verbs like will, we use the bare infinitive, so we say I will have done it and She will have done it, just as we say I will go and He will go, and not
He will goes.
