The conventional concept of “mother tongue” as the foundation of language learning is increasingly challenged in multilingual societies. This study explores the intricate relationship between language identity, emotional connections, and educational practices in multilingual families and classrooms. Drawing from qualitative interviews with language teachers who are also multilingual parents, the research examines how personal and professional experiences shape linguistic ideologies and pedagogical approaches. Using content analysis, the study uncovers key factors influencing language acquisition, including motivational dynamics, societal expectations, and the challenges of teaching additional languages in diverse environments. A central focus is the application of translingual strategies—such as code-switching and adaptive teaching methods—to create inclusive, culturally responsive learning spaces. Grounded in the framework of “inherent language”, the findings emphasize the need to move beyond rigid definitions of “mother tongue” toward a more fluid, context-driven understanding of linguistic identity. The study contributes to language education discourse by advocating for adaptable teaching strategies that acknowledge the complex realities of multilingual learners. By integrating these insights, educators can foster more inclusive and effective language-learning environments that support both linguistic diversity and individual identity development.
