The grammatical category of voice covers a wide range of phenomena, including causatives, applicatives, passives, antipassives, middles, and others. Drawing on data from over 200 languages, Fernando Z iga and Seppo Kittil illustrate the semantic, morphological, and syntactic variation of voice across languages from a range of families and regions. They approach the topic from a broad and explicit perspective, and discuss a variety of topics that are not always regarded as voice, in order to make a clear and useful conceptual delimitation. Clearly organized and accessibly written, the book will be welcomed by students and scholars of linguistics, especially those interested in how grammatical categories work.
