Ah, gotcha. Yeah, I didn’t really get what you were trying to say.

I’m not an expert, but if I recall I think the big flaw was insistence on determinism.

And to my knowledge operator grammar is universal to the degree there isn’t a counter example in the dozen of languages he explored and hundreds he had others help him with. But to my knowledge the only language he fully mapped was English.

Edit: take a look at the article on Wikipedia.
