Questions with subordinate (declarative) clauses at the end sound weird.
Can you grant me access to the document, since it is currently unavailable?
Where do I submit this, as the normal channel is closed?
Can you come back tomorrow, for he is currently unavailable?
While I understand that you can switch the position of the clause to the beginning or simply split them into two sentences, are these sentences still grammatically correct?
Edit: Stop saying why join the clauses at all! Those sentences are examples that doesnt have any meaning. Of course I know you can write it as such "Can you grant me access to the document? It is currently unavailable." But how does suggesting another way to rewrite my sentence into two answer my question??? I'm bring this up to figure this out, not to get answers on how to make one sentence two.
