Linguistic Sustainability in The Malay-Speaking Nations of The Historical Nusantara: Comparative Approaches to Minority And Indigenous Language Preservation

The survival of minority languages faces critical threats amid accelerating globalisation and cultural homogenisation. This article presents a comparative analysis of linguistic sustainability strategies in three Malay-speaking nations of the historical Nusantara—Indonesia, Malaysia, and Brunei Darussalam—each shaped by distinct colonial histories, governance structures, and sociolinguistic ecologies. Drawing on academic literature, official policy documents, and institutional reports, the study evaluates national approaches to the preservation of minority and indigenous languages across legal, educational, cultural, and technological domains. Indonesia, with over 700 living languages, adopts a comprehensive, decentralised strategy anchored in constitutional mandates and operationalised through initiatives such as the Revitalisasi Bahasa Daerah (Regional Language Revitalization) programme. This policy integrates endangered languages into curricula, trains local educators, and supports regional linguistic documentation. The expansion into digital media—via online dictionaries, apps, and content platforms—further broadens accessibility and youth engagement. However, regional disparities in infrastructure and implementation capacity challenge consistent outcomes. Malaysia’s approach is comparatively focused and regionally responsive. In Peninsular Malaysia, Chinese and Tamil vernacular schools operate alongside Malay-medium institutions, reflecting a federal commitment to ethnolinguistic pluralism. In Sabah and Sarawak, indigenous languages such as Iban and Kadazandusun receive targeted support through the Pupil’s Own Language (POL) programme and regional broadcasting. Cultural festivals and grassroots associations bolster intergenerational transmission, while institutions like the Language and Literature Bureau of Malaysia and collaborative digital projects (e.g. Wiktionary) contribute to documentation and language modernisation. Brunei Darussalam, by contrast, has adopted a preservationist and academic model in response to its concentrated linguistic ecology. While Malay and English dominate official domains, minority languages such as Tutong, Kedayan, and Dusun are sustained through limited but strategic documentation efforts. The Language and Literature Bureau of Brunei has produced bilingual lexicons, and Universiti Brunei Darussalam offers language courses and supports research on endangered local tongues. Although modest in scale, these initiatives reflect a state-led commitment to heritage preservation. The study concludes that linguistic sustainability must be pursued through context-sensitive, adaptive strategies. Indonesia’s expansive multilevel engagement, Malaysia’s differentiated and community-integrated model, and Brunei’s institutional focus each offer lessons for multilingual societies. Ultimately, a combination of legal recognition, mother-tongue education, cultural visibility, and technological innovation provides viable pathways for safeguarding linguistic diversity in the region.
