Cognitive Semantics, Philology and Persian Literature: Towards a diachronic analysis of conceptual mappings of the two Persian words, RUX and RŪY, based on the Prototype Theory

This article is a comparative study on the relation between the Prototype Theory and historical-philological semantics in Iranian languages. Regarding the actual entailments in the framework of the Prototype Theory (Rosch: 1978), in which words considered to be the central and peripheral members of a semantic category, in correlation with a morpho-phonological study on two Persian words, RUX and RŪY, a number of diachronic samples of radial categorization (Lakoff: 1990) are going to be proposed, considering the Old Iranian   as the prototype of a particular semantic network, kept in the corpus of the word. From a general perspective, this article sets out the function of the Prototype Theory and its consequences in Iranian etymological and literary studies.
