And there is at least one story about Chinese (not the generally >favored one) that would make even that a part of the language (but, if I >remember rightly, syntactic rather than lexical). > I take it that "ka'e" is a pretty clear item in most languages, though it >may take almost any role: lexical item, construction, compound, .... English >has the generic sentence as the simplest version (example 19.1, though >unmarked) and the pony itself as a longer one, with other shorter and longer >constructions available. > But I do not know of a language (including the relevant sorts of formal >logics) that has a systematic approach to the issue of whether the potential >has been actualized, the issue between "nu'o" and "pu'i." English -- and I >assume other languages in the same vein -- can make do with modals in >contrary-to-fact constructions (or maybe different but related modals): "He >could ..." in the proper context carries the force of "nu'o."

Logically, this may be because the actual doing entails the potential, >which then need not be specified explicitly.
