«The book offers a rich insight in the field of Third Language Acquisition, bridging the gap between language education and research. It explores the key linguistic and cognitive factors that make it different from Second Language Acquisition in terms of process and area of study. It is a precious resource for language learners, scholars, and teachers interested in the practical implications of the most recent research on multilingual education.»

«This book is a fascinating journey into multilingualism: going beyond the traditional monolingual-bilingual dichotomy, it brings together research from different perspectives and offers an integrated framework on additional language learning that will benefit both research and education practices.»
