Generative

Attribute of a system capable of listing the descriptions of each of a certain set of alternatives. In linguistics, a generative grammar embodies a finite number of transformation rules for construct ing a potentially infinite number of sentences of a language and lists potentially all and only the grammatical sentences of that language. In cybernetics, a generative model generates (exhibits or enumerates) hypothetical data that either match or approximate within acceptable limits those in fact observed on the system modelled. The use of such generative devices is constructivism 's alternative to testing verbal hypotheses and theories with available data. (Krippendorff )
