After I sent that message I realized that what I was describing is probably applicabe far more to predicate-based languages like Lojban or Livagian than to more naturalistic ones. In Livagian there is just one part of speech. I meant predicates involving the same set of participant roles (in a system in which the inventory of possible participant roles is not finite, and participant roles can be as idiosyncratic as predicates are). Normally a predicate's syntax-semantics has two parts: the set of participant roles, and the residue. I find it kind of takes a conceptual weight off my mind -- by making things simpler & tidier -- to group together predicates involving the same set of participant roles and that differ only in terms of the residue; the set of colour predicates would be an example.

The grouping together of predicates that differ by residue alone would I think precede other taxonomizing, so that the taxonomies serve to classify sets of predicates that differ only by residue. Taxonomies are of limited use, because it is hard to classify polyadic predicates in a taxonomy. For example, take a predicate meaning "X drinks milk Y produced by lactator Z": it's hard to see where the predicate as a whole would go in the hierarchy (except as a daughter of some very general node such as Event); it's easier to see how X, Y and Z could separately be classified, but that would work for a thesaurus but not as a vocabulary organization method (given the reasonable assumption that each vocable should appear just once). --And.
