Culturally Grounded Core Vocabulary Planning for Toba Batak: Strengthening Vernacular Resilience amid Globalization

This article proposes a culturally grounded model of core vocabulary planning for the Toba Batak language as a strategy for strengthening vernacular resilience amid accelerating globalization and national-language dominance. Departing from universalist approaches to basic vocabulary—most notably Swadesh’s list—the study argues that core vocabulary in minority languages cannot be defined solely by semantic universals but must be situated within culturally salient domains of use. Drawing on participant observation, native-speaker intuition, and ethnolinguistic documentation, the study integrates three sources of lexical selection: Swadesh-based basic vocabulary, salient everyday lexemes, and culturally grounded terms associated with kinship, ritual, ecology, and social organization. As a result of this integrative process, the combined Swadesh-based, salient everyday, and culturally grounded lexemes produce a Toba Batak core vocabulary inventory comprising 315 entries. The findings demonstrate that culturally embedded terms are not peripheral but central to communicative competence and cultural continuity. The article argues that incorporating culturally grounded vocabulary into language planning enhances both linguistic vitality and symbolic ownership, offering an alternative framework for core vocabulary development in endangered and minority languages.
