This book presents twelve papers on the use of Languages for Specific Purposes (LSPs) throughout history. From Antiquity to the present time, contributors analyse how LSPs emerged both in Europe and in other parts of the world, such as Judea, North America, and China. The historical aspect of LSPs has generally not been studied in depth, despite being part of the global understanding of the phenomenon. All aspects of professional life are tackled in this book, including administration, commerce, diplomacy, medicine, legal studies, geography, sociology, mathematics and history.This volume will naturally appeal to historians but also to linguists, sociologists, and anyone interested in languages used in a professional context. It offers a better understanding of where LSPs come from, how they emerged and how they tend to become real specialties in the teaching of modern languages.
