First Nations peoples have sustained their cultural and linguistic practices for tens of thousands of years, developing sophisticated First knowledge of nature, land, water, sky, seasons, astronomy and navigation since the earliest moments of human existence. Although they may not have relied on modern technological instruments, they have long possessed intricate knowledge systems that continue to sustain their languages, cultures, communities, and ecosystems across generations. This profound practice of First Knowledging also brings forth an awareness of First Languaging – the living and evolving expressions of First Languages that have existed since the dawn of humanity. Humans have always been languaging; yet First Nations peoples have preserved a unique clarity and connection to this essence. For them, language is not merely a means of communication but an interwoven tapestry of spiritual expression, storytelling, and embodied systems of First Knowledges that nurture both cultural and ecological worlds. This presentation explores the intersections of First Knowledging and First Languaging among global Indigenous communities, illuminating how linguistic and cultural continuity shape identity, learning, and belonging. By examining the dynamic interplay between Indigenous and dominant languages across homes, schools, and communities, it identifies pathways for embedding these epistemologies in curriculum design and classroom practice. Extending to Indigenous contexts in applied linguistics, the presentation considers how First Languaging and First Knowledging can inform transformative, inclusive, and culturally responsive approaches to Indigenous education for the future.
