Abstract
This study investigates endangered language preservation through three research questions: risk factors for endangerment, socio-cultural effects of language loss, and complexities in preservation and revitalisation. A qualitative systematic review underscores the cultural, historical and intellectual importance of endangered languages. It identifies globalisation, urbanisation, and dominant languages as key accelerators of linguistic endangerment. The findings indicate significant sociocultural consequences of language loss, notably the decline of cultural identity and heritage. The study concludes that community involvement, technological advancements, and supportive government policies are crucial to successful preservation, ensuring that at-risk languages are maintained and revitalised for future generations.
