Can Neither and Nor be used interchangeably in this context? For example:
I'm not good. Neither are you/Nor are you.
I know that I can use "Neither are you" in that context. But I wonder whether it's possible to use "Nor are you".
In your example, after "I'm not good.", "Neither are you." and "Nor are you." are equally acceptable.
We use neither and nor + auxiliary/modal verb + subject to mean ‘also not’:
A: I hate snakes. I can’t even look at a picture of a snake. B: Neither can I.
A: Jacqueline doesn’t drive. B: Nor does Gina.
