Writing is absolutely part of language. If your point is that English has weird, illogical spelling rules, then you’re right. That’s not a new observation. People have been writing about that since spelling was standardised.

And it’s been changing for a very long time.

How do you feel when you see the name “Amy”. Do you dislike it? What if I told you that the original spelling in English was “Aimee”? “Amee” was also very common once upon a time. “Amy” was a much later spelling and was once considered a cringey, trendy “Tragedeigh”. As, as I said above, were Ashleigh & Kayleigh.

But you don’t think of them that way, because they’re now common. “Kayleigh” only gained popularity 40 years ago. “Ashleigh” is less than 100 years old. And already people don’t bat an eye at it. But they will at “Emmaleigh”, even though it’s exactly the same evolution.
