[Grammar] I won't study today and tomorrow, either

[Sneymarin]

Hello, I was in a Discord server when I saw someone write the following sentence and ask if it is grammatically correct:

"I won't study today and tomorrow, either"

I told him that it looked correct to me but a native speaker said that she believes "and" should be replaced with "or" to make the sentence correct.
I think the above sentence is correct because I think it's just an ellipsis so the "and" is fine:
"I won't study today and [I won't study] tomorrow, either"
I would like to hear your thoughts about whether the original sentece is correct.
Also, the sentence has no context other than itself

Thank you for your time.

Your native speaker friend is correct. We would say "I won't study today or tomorrow". The following are all possible:

I won't study today or tomorrow.
I won't study today. I won't study tomorrow either.
I won't study today, nor will I study tomorrow.
I will study neither today nor tomorrow.

Are you saying that "I won't study today and [I won't study] tomorrow either" is grammatically incorrect? Doesn't the ellipsis make the sentence correct? or is not possible to use it that way? or it's because of "either"?

Don't worry about grammar. The point here is that the sentence is not logically correct, which means that it doesn't make good sense.

Doesn't the ellipsis make the sentence correct?

No.

or is not possible to use it that way?

Correct.

or it's because of "either"?

Partly, yes. Logically, either goes with or, not and.

I understand. Thank you for clearing my doubts, but I still have something I'm unsure of. If I use "or" instead of "and" in the original sentence, so that I get "I won't study today or tomorrow either" do I have to remove "either" or does the sentence still make sense if I keep it? I sounds unnatural to me if I keep it but I want to make sure.

You don't have to remove either, no. A lot of people might keep it, just to make the sense of the whole utterance a bit clearer, or to balance the sentence more clearly into two parts, or to add the 'or tomorrow' part as an afterthought.

However, if any of those are the aim, I'd suggest transcribing the sentence with a comma after today, to make it clearer for a reader.
