Languages in Action offers multi-perspective insights into language education, professional communication, cross-cultural understanding, and the visibility of language in society. The volume brings together theoretical reflection, empirical research, and practical applications from classrooms, higher education institutions, and public spaces. Readers will find innovative approaches to language learning and teaching, linguistic landscapes, and interdisciplinary research linking emotional expression with identity and migration. From drama-based pedagogy to multimodal learning environments and the use of social media, the thematic breadth makes this volume a valuable resource for educators, researchers, and anyone interested in how language evolves and functions across contexts. Published in honour of Professor Danuta Wiśniewska, the book also reflects her person-centred approach, academic vision, and lifelong commitment to action-oriented language education.
