@elilla I agree but I have to mention a few things because of course I have to. Sorry. Not trying to argue, these are kind of questions phrased as opinions. Does this make any sense?

The no prescriptivism thing can turn around to bite you because most of these words have gained secondary meanings in daily vernacular. ‘Dialect’ can refer to a dialect that is not the most common one in a given language.

I’d still say grammar errors are a thing, people just don’t understand what they are. I think when a person makes an unintentional slip up (i.e. something that they themselves think is a mistake), it could count as an error. Like if I wrote ‘on’ two times when I should’ve written it once (as in ‘he was standing on on the table’), I’d think that’s an error. But if it’s something that was done intentionally, it by definition can’t be an error, it’s just not.

And yes, I know I just pulled a ‘you’re using this word wrong’ on the word ‘error’. Or maybe not? We all agree what an error is, so I’m just saying that something that people commonly think is an error is in fact not? (AAAAAAAAAAAAAAAAAAAAAAAAA)

Sorry again. First time I see anybody who cares about linguistics at all here.
