Cognitive linguistics plays a crucial role in understanding language evolution by analyzing how human cognition influences linguistic structures, meaning, and change over time. Unlike formal linguistic theories, cognitive linguistics focuses on conceptualization, metaphor, and embodiment as key mechanisms driving language development. This study examines the role of cognitive processes such as metaphorization, categorization, grammaticalization, and conceptual blending in shaping linguistic evolution. The research highlights how metaphorical mappings structure thought, how prototype theory affects word meaning shifts, and how grammaticalization transforms lexical items into functional elements. Conceptual blending, a cognitive mechanism that integrates mental spaces to generate new meanings, further explains linguistic innovation. Findings indicate that language change is not arbitrary but follows systematic cognitive principles, reinforcing the embodied nature of linguistic evolution. By integrating cognitive science, historical linguistics, and psycholinguistics, this study provides a comprehensive framework for analyzing language evolution. Future research should explore the intersection of cognitive linguistics with neurolinguistics and computational modeling to enhance understanding of the cognitive foundations of linguistic change.
