Austroasiatic Syntax in Areal and Diachronic Perspective elevates historical morpho-syntax to a research priority in the field of Southeast Asian language history, transcending the traditional focus on phonology and lexicon. The volume contains eleven chapters covering a wide range of aspects of diachronic Austroasiatic syntax, most of which contain new hypotheses, and several address topics that have never been dealt with before in print, such as clause structure and word order in the proto-language, and reconstruction of Munda morphology successfully integrating it into Austroasiatic language history. Also included is a list of proto-AA grammatical words with evaluative and contextualizing comments.
