In this groundbreaking collection, editorsLindsay G. Oades, Narelle Lemon, Jacqui Francis, and Tim Lomasexplore wellbeing literacy-the capability to understand and effectively use wellbeing language to enhance flourishing for oneself, others, and society. Drawing together international scholars across diverse disciplines, this volume examines how intentional communication about wellbeing serves as a critical mechanism for personal and collective thriving.Moving beyond simplistic approaches to wellbeing, the contributors investigate how wellbeing literacy functions as a relational, contextual, and holistic capability that bridges individual experience with broader social systems. Chapters examine wellbeing literacy across different life domains, cultural contexts, and developmental stages, offering both theoretical frameworks and practical applications.This pioneering work challenges readers to consider: How does wellbeing literacy manifest in various contexts? What role does it play in policy development? How might it serve as a lever for social change? Through multimodal and interdisciplinary perspectives, the collection illuminates the dynamic interplay between language, knowledge, and skills that enable flourishing across individual, communal, and systemic levels.Essential reading for researchers, educators, and practitioners seeking innovative approaches to fostering wellbeing in an increasingly complex world.
