Mother tongue preservation as systemic resistance to linguistic imperialism and cultural erasure in global education

Indigenous languages are not just vehicles of communication but repositories of ecological and spiritual knowledge, encoding sustainable practices and cosmological frameworks. For instance, the Hopi language in the U.S. Southwest contains terms for weather patterns that align with modern climate science, yet these are dismissed as 'primitive' by dominant education systems. The loss of these languages represents a loss of adaptive knowledge systems that have sustained communities for millennia.

The suppression of indigenous languages is a centuries-old strategy of colonial and neocolonial power, from the Spanish conquest's imposition of Castilian to British colonial education systems in Africa and Asia. The 19th-century 'civilizing mission' framed indigenous languages as obstacles to progress, a logic that persists in modern education policies. Structural adjustment programs in the 1980s and 1990s further institutionalized this erasure by prioritizing English and French in African schools.

Cross-culturally, language loss is linked to the erosion of communal identity and social cohesion, as seen in the decline of Gaelic in Ireland or Quechua in Peru. In contrast, countries like Finland and Norway have successfully integrated mother tongue education into national identity, demonstrating that linguistic preservation can coexist with modernization. Indigenous communities in Australia and Canada have revived languages like Warlpiri and Inuktitut through community-led education, offering models for resistance.

Neuroscience confirms that mother tongue acquisition in early childhood enhances cognitive development, emotional regulation, and academic performance, debunking myths of linguistic 'deficiency.' Linguistic anthropologists argue that language loss leads to the extinction of unique worldviews, as each language encodes distinct ways of perceiving reality. UNESCO's 2003 Language Vitality framework highlights that language shift is driven by institutional policies rather than natural assimilation.

Artistic traditions, from oral poetry to ritual chants, are inseparable from language and serve as living archives of cultural memory. The suppression of indigenous languages has led to the decline of traditional art forms, such as the loss of Inuit throat singing or Aboriginal dot painting's cultural context. Spiritual practices, including prayer and healing rituals, are often linguistically specific, and their erosion fragments communal spiritual frameworks.

By 2100, up to 90% of the world's languages could disappear, taking with them irreplaceable knowledge systems critical for climate adaptation and biodiversity conservation. Scenario modeling suggests that integrating mother tongue education into STEM curricula could enhance innovation by leveraging diverse cognitive frameworks. Conversely, continued linguistic imperialism risks accelerating social fragmentation and ecological collapse by severing communities from their adaptive knowledge.

Marginalized communities, particularly indigenous women and children, are disproportionately affected by language loss, as their knowledge is often the first to be devalued in education systems. The erasure of mother tongues silences women's roles as primary knowledge transmitters in many cultures, reinforcing patriarchal structures. Children in marginalized linguistic groups face higher dropout rates when education is not delivered in their mother tongue, perpetuating cycles of poverty.
