"Polinsky provides a new and systematic approach to describing ergative languages that offers attractively simple categories, clearly defined and empirically testable conditions, and data from a set of relevant languages to back up the suggestions made. The dichotomy between PP-ergative and DP-ergative languages proposed is essentially theory-neutral and makes a number of interesting observations awaiting further testing. As such, this monograph will be ofinterest to anyone working on ergative languages, particularly on syntactical ergativity, and to typologists in general. Certain parts (esp. Chapter 8) may also be of interest to historical linguists. Theanalytical methods used and proposals made concerning specific languages may further be relevant for linguists working in transformational syntax or on Polynesian and Caucasian languages."--Linguist List
