What's surprising, InOBU? What I was saying is how we learn to recognise when a spelling is "wrong" is because we've seen it so often spelt one way that it looks wrong when it's spelt another way. Well, that's true for me anyway - my wife tells me about all kinds of rules that exist, but I could never learn that way.
The same you learn a tune by ear, you learn a spelling by eye.
Of course it doesn't work the same way for everyone. The same way that some people just can't pick up a tune, some people are can't be comfortable with written words. If you have to choose, being able to pick up a tune is a lot more important.
Is there a word like dyslexic for people who can't learn to read music? Like me.
