Overall this is an informative and very well-written book, which will clearly benefit advanced students of historical linguistics and readers who require a more in-depth treatment of the history of the languages prehistory than is found in traditional histories and grammars. It provides a successfully updated view of the internal history of the language, which takes into account more recent approaches to language change, and encourages readers to make links with neighbouring linguistic disciplines, and is a welcome addition to existing reference works.
