Question

1. It's okay for you to go home now.
2. It's okay your going home now.
3. It's okay if you go home now.
-----------------------------
#1 is correct and ''It' refers to 'for you to go home now'. Am I right?
What about #2? Is #2 grammatical? Does 'it' refer to 'your going home now'? In Sentence 3, does 'It' refer to 'if you go home now'?

Answer 1

1 and 3 are correct. 2 is incorrect.

Again, "it" is used as an impersonal pronoun to get the sentence going. It has no antecedent.

Answer 2

Thank you for your help.

1. For you to go home now is okay.
2. Your going home now is okay.
3. To go home now is okay.
4. Going home now is okay.
[What about these sentences? Can we use them?]

Answer 3

All are grammatically correct, but some are clunky or not used in common speech. #1 and #4 are the best, in my opinion.
