Hello!
- The dog is chasing a cat under the table.
inverted
- Under the table is the dog (which is) chasing a cat.
Is it all right, please?
You can't invert the sentence without disambiguating the meaning first.
Are both the dog and the cat under the table, with the dog chasing the cat? - 1. Or are neither under the table, with the dog attempting to make the cat go under the table? -2.
Both readings are possible.
1. "Under the table, the dog is chasing the cat." 2. "Under the table is the place to which the dog is trying to chase the cat."
But neither reads naturally.
