inversion and parts of a sentence
I'm wondering what part of the sentence ''there'' and ''point'' are and what the subject is in these two cases:
''There is no point / No point is there''
As far as I understand, the inversion doesn't change the meaning, so logically (since the order in which you add two numbers doesn't matter), in both sentences the subject should remain the same. But it looks like that the subject of the first sentence is ''there'' and of the second is ''point''.
Could someone explain?
