The thing to remember about all this is that {lo broda} is the same, semantically, as {da poi [ke'a] broda}, with the exception that the latter also asserts the existence of such a thing, while the former doesn't. ({le broda} is correspondingly {da voi broda}). Similarly, "the x such that Fyx" is {da poi de se broda da[/ke'a]} in {da poi} syntax, and {lo se broda be de} as a gadrified sumti (note the necessity for the link with {be}; also note I'm glossing over the implicit existential quantifier on {de} as well). Given this parity between {lo broda} and {da poi broda}, you can easily see how to create something of any complexity: da poi le nu rode rodi zo'u de krici lenu di zmadu da kei kei cu na cumki X which-is-such-that: (the-event-that: for-all Y, for-all Z: Y believes (the-event-that: Z exceeds X ) ) is not possible (my grouping above may not show off the Lojban grouping perfectly, but I think it's right in Lojban). The only thing less than gadri-like about this phrasing is the fact that without some sort of quantification it implicitly quantifies this {da} with existence: at least one of these things is claimed to exist. But you can probably fix that too, with appropriate quantification. pc, I hope I didn't miss something obvious; I know of your expertise in formal logic. ~mark
