This study reflects the author's efforts to synthesize ideas drawn from various linguistic theorists, especially Schlesinger, Chomsky, and Fillmore. The first section gives the theoretical background for the study. The second section discusses roles, relations, and constructs. The final section discusses the applications of the study to teaching and research. In this study, a distinction is made between those semantic constructs encoding events and those encoding states. In the model presented, the basal component of the grammar generates constructs which consist of a modality index and a proposition. The proposition consists of related basal constituents and their respective semantic roles. The operative component assigns grammatical functions to basals, categorizes them as nouns, verbs, etc., supplies syntactic features and functions, and determines the sequential order of elements in overt sentences. The expressive component contains phonological elements and rules. (Author/TS)
