I'm interested how many auxiliary verbs can stand after "as" and "so". By "how many" I mean one (e.g. "would") or two (e.g. "would be") or three (e.g. "would have been"). And by what rule should we choose this number?
As I understood from here:
(1a) He got divorced, as his parents had years before. — correct
(1b) He got divorced, as his parents had done years before. — correct
(1c) He got divorced, as had his parents years before. — correct
(1d) He got divorced, as had done his parents years before. — correct
Also I think:
(1e) He got divorced and so had his parents years before. — correct
(1f) He got divorced and so had done his parents years before. — correct
My example making up by analogy with #1a-f:
John:
(2) I would eat something right now.
Peter:
(2a) As I would. — correct
(2b) As I would do. — correct
(2c) As would I. — correct
(2d) As would do I. — correct
(2e) So would I. — correct
(2f) So would do I. — correct
If we add "like to", I think the correctness doesn't change:
John:
(3) I would like to eat something right now.
Peter:
(3a) As I would. — correct
(3b) As I would do. — correct
(3c) As would I. — correct
(3d) As would do I. — correct
(3e) So would I. — correct
(3f) So would do I. — correct
As I understood from here:
(4a) Usually the cake would be excellent, as the coffee would be. — correct
(4b) Usually the cake would be excellent, as would be the coffee. — correct
(4c) Usually the cake would be excellent, as the coffee would. — incorrect
(4d) Usually the cake would be excellent, as would the coffee. — incorrect
Also I think:
(4e) Usually the cake would be excellent and so would be the coffee. — correct
(4f) Usually the cake would be excellent and so would the coffee. — incorrect
My example making up by analogy with #4a-f:
John:
(5) I would be glad to eat something right now.
Peter:
(5a) As I would be. — correct
(5b) As would be I. — correct
(5c) As I would. — incorrect
(5d) As would I. — incorrect
(5e) So would be I. — correct
(5f) So would I. — incorrect
Do you agree?
