The paper explores the pivotal role of language as a catalyst for fostering intercultural understanding within the framework of multilingual approaches in global citizenship education. In an increasingly interconnected world, language is a dynamic tool for bridging cultural divides and nurturing empathy, respect, and appreciation for diverse perspectives. Multilingualism, embraced within educational contexts, becomes instrumental in shaping informed global citizens equipped with the skills and mindset to navigate the complexities of our interconnected world. This paper delves into the theoretical underpinnings of multilingual education and its implications for global citizenship, emphasizing the transformative potential of linguistic diversity. By incorporating diverse linguistic and cultural perspectives into curricula, educators can cultivate a sense of curiosity and open-mindedness among students, facilitating meaningful intercultural dialogue and collaboration. Furthermore, the paper highlights the emerging trends in multilingual education, such as translanguaging pedagogy and content and language-integrated learning (CLIL), as practical approaches to promote language proficiency and intercultural competence. These strategies empower students to leverage their multilingual learning, communication, and problem-solving skills, fostering a deeper understanding of global issues and promoting social justice and sustainability. Through a synthesis of theoretical frameworks, empirical research, and practical insights, this paper seeks to contribute to the ongoing discourse on the role of language in promoting intercultural understanding and global citizenship. By recognizing language as a powerful tool for building bridges across cultures and fostering inclusive societies, educators and policymakers can work towards creating more equitable and interconnected communities where linguistic diversity is celebrated and valued. In addition to exploring the theoretical foundations and practical applications of multilingual approaches in global citizenship education, this study delves into the importance of policy frameworks and institutional support in fostering linguistic diversity within educational settings. Effective language-in-education policies that recognize and promote the linguistic rights of all learners are essential for creating inclusive learning environments where students feel valued and empowered to express themselves in their mother tongue. Furthermore, the paper discusses the need for professional development opportunities for educators to enhance their pedagogical practices and intercultural competence in multilingual settings.
