The collection of articles in this book presents some of the latest developments in the study of the phenomenon of phraseology in legal and institutional discourse. These contributions come from two main sources: selected papers from a workshop devoted to Corpus Approaches to Legal Phraseology organised by the editors of this volume during the XX European Symposium on Languages for Special Purposes held in Vienna in July 2015 and some recent invited contributions to the topic made by both renowned linguists and young promising researchers.This book is an attempt to continue, update and extend different avenues of research signalled in our earlier edited publication of a special issue Legal Phraseology Today. A Corpus- Based View in Fachsprache: The International Journal of Specialised Communication, in 2015. Much of the ground covered in the next two sections has already been explored in the introduction to that special issue (Gozdz- Roszkowski and Pontrandolfo 2015).
