In today’s knowledge-based society, exploring the dynamics of communicating specialised contents to the lay public is an undoubtedly topical issue. However, popularization still remains a rather unexplored territory and recent contributions to the field seem to lack a consistent methodological orientation, with hesitations in terms of shared and codified definitions. The contributions to this volume constitute a step forward in the field of popularization studies. New scenarios have been explored with a view to providing shared theoretical and descriptive models from a linguistic perspective and investigating the way popularization is characterised and instantiated, also taking into account its intercultural dimension. The research methods and tools draw upon the analytical framework of discourse analysis, pragmatics, corpus linguistics and genre analysis.
