Re: has, is, of

Thanks for this post Karen, I am wondering the exact same things. I would
love to know "if there is anything coherent to say about these property
name choices" as well.

but please in a more explicative way than:

"This can be read either
o is the value of p for s
or (left to right)
s has a property p with a value o
or even
the p of s is o"

Because that makes my brain hurt real bad.
