Internationalisation is key to a modern and diverse higher education. Closely related to this is the successful integration of different cultures and languages. This book explores the dynamic relationships between English as a Lingua Franca (ELF), intercultural communication competence (ICC), internationalisation, and the use of the English language in international higher education. Featuring contributions from authors from Türkiye, Slovenia, Thailand, Taiwan and Norway, the chapters discuss topics such as translanguaging, language-related policies in internationalisation, issues of language and interculturality from a contextual point of view of pedagogy, and provide critical reflections on perceptions and orientations in support of higher education internationalisation. Ultimately, the book provides a comprehensive understanding of how the English language functions as a tool for intercultural engagement in academic settings, and the ways in which it is encountered and perceived by researchers, leaders, and practitioners. This book will be valuable reading for applied linguists, teacher educators and researchers, and graduate students in higher education involved in internationalised higher education through teaching, projects and activities.
