In recent decades, there has been growing interest in the pluri/multilingual learner’s language repertoire and foreign language learning. Multilingual learners use their linguistic repertoire and cultural knowledge in everyday life and interact fluidly with other speakers and texts in different languages. According to the Council of Europe (2001: 34), individual language components are “unevenly differentiated according to the learner’s experience and in an unstable relation as that experience changes”. Several studies provide arguments in favour of multilingual education because it (1) enhances multilingual learners’ cognitive and multitasking skills

and (6) promotes empathy and tolerance. Plurilingual learners can better appreciate diversity and belonging in multicultural societies. In addition, various European Commission policy documents underline the importance of pluri/multilingual education.

(5) equips learners with problem-solving, interpersonal and intercultural communication skills

(4) improves academic achievement in a variety of areas, not just language-related subjects

(3) promotes cultural awareness and understanding of cultural diversity

(2) enables higher language proficiency in multiple languages
