xorlo
Hello everyone.
I have recently got acquainted with the (virtually accepted, AFAIK) xorlo
proposal:

There are several things I don't understand about it. Foremost, we now have
that
- Any term without an explicit outer quantifier is a *constant*, i.e. not
a quantified term. This means that it *refers* to one or more
individuals, and changing the order in which the constant term appears with
respect to a negation or with respect to a quantified term will not change
the meaning of the sentence. A constant is something that always keeps the
same referent or referents. For example {lo broda} always refers to brodas.
In {mu da poi broda zo'u da brode}, "da" is a quantified variable, bound by
the quantifier *mu*, and it takes its values from the set of all things
that broda. (Within the scope of the quantifier, it acts as a constant term,
but it cannot escape as a constant out of that scope.) Any term with a
quantifier in front takes values from the set of things over which the
quantifier runs. When an unquantified term is quantified, the quantifier
runs over the referents of the unquantified term.
I don't quite understand how can all such terms be constants. For instance,
consider the *jufra*
- lo mu nanmu cu tavla lo ci ninmu*
Under xorlo, *lo mu nanmu* refers to some 5 men/boys and *lo ci ninmu* refers
to some 3 women/girls. However, which men speak to which men? Before xorlo,
the default outer quantifier of *lo* was *su'o *thus the above would implied
that *at least one* of the men talks to *at least one* of the women. Of
course, before xorlo that would also mean that only 5 men exist in the
universe and only 3 women. Similarly, before xorlo
- le mu nanmu cu tavla le ci ninmu*
meant that *all* of the men talk to *all* of the women, since the default
outer quantifier of *le* was *ro*. What happens under xorlo? Do both phrases
mean "all"? "at least one"? Or is it context defendant, and the phrases
could mean anything? The later possibility suggests that the weakest
interpretation is safest, namely the interpretation with "at least one".
In other words, since we're doing about 5 men and 3 women rather than 1 man
and 1 woman, it seems that a quantifier is logically necessary, and such a
term cannot be a "constant".
Secondly, what is meant by *lo* becoming "generic"? What is the difference
from the earlier convention?
Many thx for any help!
Best regards,
