The book "Youth Languages: Multilingual - Contrastive - Intercultural" offers a comprehensive insight into the multifaceted world of youth language. It brings together 19 contributions from international linguistic research on youth language, addressing various aspects of youth languages in Europe. The authors analyze factors such as style mixing, code-switching, and language intersections, employing different theoretical and methodological approaches. The anthology also highlights the application of these language variations in media and education, supported by examples from dictionaries, advertising texts, teaching materials, literature, and music. This interdisciplinary perspective makes the work a valuable resource for students, educators, and anyone interested in linguistics and intercultural communication.
