I have doubts when writing negative sentences that mention two alternatives, I don't know if I have to use “nor” or “or”.
- You mustn't drink soda nor beer. Or
- You mustn't drink soda or beer.
I would use “nor” because it's a negative sentence, but I don't know why some apps (like Grammarly) say that it should be “or” instead. It would be amazing that someone here explains me because I investigated, and I don't get it. Thanks in advance.
