Whereas for me it refers to a two-membered mass. If we can't
get past this stumbling block, we'll continue talking past
each other.

Yes, unfortunately it has been said authoritatively too many
times. I never saw actual usage take advantage of this "feature"
though.

In official Lojban, yes, {[pisu'o] lei bolci} is some part of
the mass of balls, so it can refer to the one ball.

But even in official Lojban I have never before seen the claim
that {le 101mei} could refer to the mass of one ball. It seems
outrageous and it would seem to make {mei} fairly useless.

Well, I guess it is possible to set up a classification scheme,
but in the end you need to examine the particular context before
deciding in which class a given property falls. It's not something
you could put in a dictionary.

Exactly. And the same works to some extent for every property,
some being of course more clear cut than others.

I hope I have not agreed with that, since I think that the set of
exactly the members is the relevant one, if we need to talk
of any set at all. And the place structure I had proposed for
{mei}, which you said you liked, had the mass of cardinality n
in x1, and a supermass (of indeterminate cardinality) in x2.

{le'i gerku} is the set of dogs I have in mind, and {piro lei gerku}
is the mass of the very same dogs. {pisu'o lei gerku} is some part
of that mass. {lei gerku cu gunma le'i gerku} is true with any of
the two quantifiers for {lei}. Since it is true with {piro} it
has perforce to be true with {pisu'o}. I don't see that any of this
requires that the mass have different members to those of the set.

Nope. {na} has scope over the whole bridi. Your version would be
the one with {naku}.

No, I certainly can't give you a percentage. But there is no magic
formula that will tell you how many members have to be tired for the
group to be considered to be tired, that goes with the context.
Even for one person, there is no rule that will tell you when they
are tired, that also depends on the context.
