Actually, there's an issue here, and I'm not sure how to resolve it.

I think we agreed that
(i) if {lo broda be da} occurs not in the scope of a quantification of
    {da}, the resulting existential quantifier has scope only within the
    lo-phrase - i.e., referents are claimed to satisfy
    EX x. broda(_,x) .

Meanwhile,
(ii) if {da} is already quantified, then {lo broda be da} is interpreted
    as a skolem function.

But then how to handle
{ge broda da gi brode vau lo brodi be da} ?


The same problem occurs with {da .e ko'a lo broda be da}, if my
understanding of the interaction between sumti connectives and
quantifiers is correct.


I'm not seeing any solutions other than either (a) choosing one of (i)
and (ii), and declaring the other disallowed; (b) just accepting this as
an ugly exception to the wide "scope" of description sumti.

I don't like either of these.

Any better ideas?

Martin
