Good morning, people. I know there are some related posts, but they don't answer my many questions. All ELL and other forum links are purple. Believe me, hahaha.
1 - In questions/negative questions, can ANY follow a singular noun?
Q: Do you have a pen to lend me? A: No, I don't have any pen/pens.
p.S.: The doubt arose because we know that "ANY" is not commonly used with singular count nouns. I don't know if the exception applies in this case.
2 - Is it okay to drop "any" and leave just not alone?
Q: Don't you have pens?
That sounds pretty general to me.
Q: Don't you have any pens?
It sounds like "Any kind of."
3 - Are NO and NOT ANY "identical", meaning 0? Does Using NO turn the sentence more emphatic?
A: I don't have any bad intentions.
This doesn't sound like "any kind of" to me, as in the previous example. But it sounds like "zero/0"
B: I have no bad intentions.
Thank you in advance.
