A toponym transcends mere nomenclature for a location; it serves as a portal to the essence and attributes of that place. Within the framework of this investigation, toponyms within the western Lembang geological landscape do more than just label; they encapsulate and articulate the seismic history of the area in all its intricate facets. To conduct this study, a theoretical lens grounded in linguistic anthropology was employed, alongside an ethnographic qualitative methodology. Based on the interview, observation and document analyses, the findings of this study unveil the structural diversity of place names in the western Lembang geological landscape, manifesting as merging patterns and linear patterns. The name-forming lexicon within the merged pattern encompasses nouns, verbs, and adjectives. Furthermore, the form and meaning of these lexicons that constitute place names, steeped in local wisdom within the western Lembang geological landscape, eloquently echo the Sundanese people's profound connection with the natural world, the surrounding flora, and fauna. This research illuminates the intricate interplay between language, culture, and the geological heritage of the region, shedding light on the intimate relationship between the Sundanese community and the environment they inhabit.
