ABSTRACT
As diachronic changes in the internal structure of a language is characterised by an unbalanced relation between lexis and grammar, that is, lexical changes are more obvious than grammatical ones, lexical studies remain more prominent than grammatical studies. The lexical-grammatical approach, in which lexical and grammatical perspectives are integrated, has been adopted to examine ontological issues as to what lexical concepts are composed of and epistemological issues as to how lexical meanings are experienced. Natural language is primitively experiential, but linguistic experience cannot be reconstructed without technical measures; technical reconstruction in turn brings about technical consequences. The argument structure-qualia structure coupling mechanism organises lexical items into the semantic network. The semantic network on the linguistic level corresponds to the conceptual network on the cognitive level. In this sense, lexical ontological semantics not only provides analogous devices to model the linguistic system but also offers insights into the cognitive system.
