Reading this link, I'm wondering if my initial formulation wasn't correct after all? It depends on how you categorize "vegan" but in the link they state that "material" is the only group of adjectives that comes after "nationality", and of the categories listed, I'd say vegan fits the "material" category best?
Or am I misinterpreting something?
English is my second language, but I do want to speak it as well as possible, hence my efforts to understand this topic. I do apologise for pestering you all with these questions tho.
It's amazing: I only learned about that when I when I was middle-aged, reading some internet article. But as a native English speaker, I subconsciously already knew this rule, somehow, like it's hard-wired somehow. They never taught this to us in school.
That's what I mean: you just learn it by being immersed in the language and hearing it every day and only knowing that language, so you learn to use it the way everyone around you uses it. So there's actual rules to the language that, as a native speaker, you're not even aware are rules. It probably took some ESL person to notice this rule even existed, and to figure out how it actually worked and write it down.
