It is super common for authors to introduce new words or bend the grammar. Again, bloodydamn Shakespeare invented so many new words! Oh, and bloodydamn is such an invented word from a very contemporary and popular book series called the Red Rising series. You don't even need to be high brow to invent new words and get away with it.
I urge you to explore more literature and poetry. There is more to English than what they teach you at school.
That's not at all what I said in my comment and I'm not at all refuting your point that languages change and can vary depending on who is using it.
No, it hasn't. None of it has, ever.
So far, you have been wrong about writing, about human language (specifically, English), about programming languages (specifically, Lisp and Java), about poetry, and about the rules of English and how they're set.
I am intrigued. Is this performance art? What next?
Are you denying that dictionaries and comprehensive books on English grammar exist?
This is especially insane when talking about English. What English? American English? What group? African-American English that introduces whole new grammatical concepts? Indian English? Even two people grown an raised in London can have wildly different ways of speaking depending on their class backgrounds and many other factors. There isn't one English.
And it is ever evolving. Shakespeare English is vastly different than 21st century English. In fact Shakespeare himself invented roughly 1.7k words that we still use today.
