Cognitive Semantics and Grammaticalization: A Case Study of xâstan ‘to want’

Based upon diachronic-cognitive linguists, language structure is the product of our interaction with the world around us. The way we build discourse and develop linguistic categories can immediately be derived from the way we experience our environment and use that experience in specific communication. Thanks to recent works on the evolution of grammatical categories e.g auxiliaries, we now have a sizable knowledge of the main patterns of grammaticalization which allows for fairly reliable linguistic reconstructions and hypotheses on genetic evolution through main cognitive processes e.g semantic bleeching. Following the doctorines of cognitive semantics, the present proposal bears an attempt to discover and define which aspects of meaning of a lexical source are lost and which are preserved through grammaticalization. Analyzing a specific grammaticalized product, namely the auxiliary verb xâstan, the future marker, through the lexical xâstan ‘to want’ in Persian, we will suggest that the evolution of the target grammatical meaning, the future, through grammaticalization process occurs applying semantic bleaching by way of which the entire idiosyncratic semantic features are vanished but the image-schematic structure. This must mean that an image-schema is abstracted from the earlier lexical sense since it would be potentially much more immanent and pervasive than the fully fleshed-out lexical meaning.
