I'm still not sure I understand.

That is: > {lo pa broda naku brode} = {su 'o lo pa broda naku brode} yes, this is uncontroversial > = {naku zu'o ro lo pa broda cu brode} = {ro lo pa broda na brode} zo'u? It is unnecessary here. I don't agree that the last 2 are equivalent to the first 2, since the first 2 mean: ge su'o broda na ku brode gi lo'i broda cu pa mei and the second two mean: na ku ge ro broda cu brode gi lo'i broda cu pa mei > and, again with exclusion of the 0 case of {ro} > = {lo pa broda na brode} > > Now, I may have a problem with the semantic of {na} and {naku}, > specifically with the negation of the referent existence: > providing that with {lo broda cu brode} I claim 2 things, > the existence of at least one {broda} referent, and the {brode} > relationship, does the {na} or {naku} in {lo broda na/naku brode}, > apart from deying the {brode} relationship, still claim (or imply) > the existence of at least one {broda} referent? > I would say yes with both {na} and {naku}, but after reading again > the related chapters of the book, I can't say it has been made explicit > (or I failed to see it). Your assessment of the current state of play is accurate, I think, but as I have said to pc, where there is dispute about whether some piece of meaning is within the scope of what is asserted or outside it (i.e. presupposed/conventionally implicated), the default/null hypothesis is that it is within. This is because Lojban makes little if any use of presupposition/conventional implicature (outside of UI, at least), does not discuss it in Woldy, and has no established tradition of acknowledging its existence in Lojban. > > 2. {lo pa} makes a claim.

But we had already established the reasons for wanting to signal that there is only one broda.
