Are these grammatical, IYO?
You have actually to leave now.
He has really to get his stuff together.
You have actually to leave now.
He has really to get his stuff together.
unit lexeme
both sound strange to me.
I would say:
You have to actually leave now/You actually have to leave now.
He really has to get his stuff together/He has really got to get his stuff together.
I would say:
You have to actually leave now/You actually have to leave now.
He really has to get his stuff together/He has really got to get his stuff together.
To me at least neither of those are grammatical at all, and do not even sound merely "strange". To me, "have to" cannot be split by some intervening adverbial under any conditions, and rather functions as if it were practically a single word as a whole.
I don't agree that it's completely 100% ungrammatical, but it's not what I'd say. Maybe it's only 99% ungrammatical. Perhaps someone could place the 'really' or 'actually' in those spots for some special effect, with the right tone of voice.
To me, if seems better than "He has to get his really stuff together." (unless there's something called "really stuff".).
