The book is divided into four parts. Part I deals with historical linguistics, including discussion of human genetics, archaeology, and cultural history. Chapters in Part II explore language contact between Malayo-Polynesian and unrelated languages, as well as sociolinguistic issues such as multilingualism, language policy, and language endangerment. Part III provides detailed overviews of the different groupings of Malayo-Polynesian languages, while Part IV offers in-depth studies of important typological features across the whole linguistic area. The Oxford Guide to the Malayo-Polynesian Languages of Southeast Asia will be an essential reference for students and researchers specializing in Austronesian languages and for typologists and comparative linguists more broadly.
