Interested in Language
I know that "If I had been in London at that time, I would have come to see you" means the same like "Had I been in London at that time, I would have come to see you" but I would like to ask what is the chief difference between the two modes (Is Had noun been more formal than If noun had been? I am asking because I have come across Had noun been chiefly in literature).
Thank you very much
The inverted for (Had I been ...) is more formal.
