I'm talking about orthography because the thread is about how language (German originally) is written - i.e. orthography. You didn't mention anything about grammar until this latest comment; your previous comment mentioned orthography and vocabulary. All I did was continue talking about what I was already talking about.
The rules are so convoluted and nonsensical (the adjective order is a great example)
The adjective order is an old, overblown meme. The meme came with a ready-made exception ("big bad wolf") which is no less of an exception for the fact that it came with ready-made excuse ("ablaut reduplication").
Did you notice that "old, overblown meme" violates the order (opinion follows age)? That's because it's overblown.
Did you know that other languages have adjective orders of various specificity and rigidity?
Yes, it's a fascinating topic, and yes, there are many markers of non-native English speaking which are impractical to teach. But it sounds like you're trying to steer the conversation somewhere I don't want to go, and I'm not going down there. As soon as you start categorising languages as "real" or "not real" you're on your own. Your misunderstanding of the Sapir-Whorf hypothesis, likewise.
