@andyb It IS obtuse and arbitrary. Language is like that. Do. you say "I went to hospital" or "I went to the hospital"? When to use "the" is as obtuse and arbitrary as the "u" in "colour". Is "in" the opposite of "out"? How about "Roll the carpet out"? Oops, that's "Roll the carpet _up_". So yeah, welcome to language. It's been our friend for a long, long time, but it's always been like this. Free free to unfriend it 🙂
@andyb I have a theory: All languages have a complexity budget. English spends it on spelling and vocabulary size. Japanese spends it on different ways to speak depending on relative status. And so on. So I don't think English is worse. I think it's just weird in some different ways (and some of the same ones.)
