Monograph on Ergativity from Masha

New from Maria Polinsky, Deconstructing Ergativity: Two Types of Ergative Languages and Their Features. In this book, Masha argues that ergative languages instantiate two main types: one where the ergative subject is a prepositional phrase (PP-ergatives), this being syntactic ergativity, and one with a noun-phrase ergative (DP-ergatives). The book provides an analysis of both types, and traces the diachronic connection between them. It also illustrates the two with extensive descriptions of Tongan (PP-ergative) and Tsez (DP-ergative), based on Masha's original fieldwork.
