Yes, I meant {ce'u}. I used to use {ke'a} before {ce'u} was
invented. They serve basically the same function, one for
relative clauses and the other for properties.

Yes, though there are no negations in this case. The order
of universal and existential quantifiers is significant.
The conjunction is like a universal quantifier, and the
disjunction is like an existential for this purpose,
so in this example we have a universal (with .e) and an
existential quantifier (with da), and the order in which
they appear is significant.

I'm not sure this has been explicitly stated in the book,
but I don't see how it could work any other way.
