What is the origin of the Romance languages and how did they evolve? When and how did they become different from Latin, and from each other? Volume 2 of The Cambridge History of the Romance Languages offers fresh and original reflections on the principal questions and issues in the comparative external histories of the Romance languages. It is organised around the two key themes of influences and institutions, exploring the fundamental influence, of contact with and borrowing from, other languages (including Latin), and the cultural and institutional forces at work in the establishment of standard languages and norms of correctness. A perfect complement to the first volume, it offers an external history of the Romance languages combining data and theory to produce new and revealing perspectives on the shaping of the Romance languages.
