This chapter focuses on aspects of multilingualism and intercultural competence in the subject of English in the LK20 curriculum. Both terms are first thoroughly defined and discussed; the text then presents a content analysis of the new national curriculum (LK20) with a specific focus on the Core Curriculum and Curriculum in English. The authors find that both concepts, multilingualism and intercultural competence, are well incorporated in the LK20 English curriculum, appearing both separately and in tandem. The subject of English is presented as an important building block in pupils’ dynamic and developing linguistic and (inter)cultural repertoire. As the first additional language taught in school, English has the potential to be a catalyst for both multilingual and intercultural competence (MIC). However, becoming this catalyst in practice may depend on teachers’ and school administrators’ interpretations, competences, and attitudes.
