volumes of the handbook series The World of Linguistics, which aims to present an up-to-date overview of linguistic work on the world’s languages. The volume provides descriptions of around twenty languages which are spoken in eastern Turkey, western Iran and northern Iraq. The area covered in this book is linked to the ancient cultural core of Mesopotamia, and also includes the mountainous regions of the Zagros in the southeast and extends up the Anatolian Plateau to the outliers of the Caucasus. This area is subdivided into five regions in this book, and each section of the book deals with the languages of each region: eastern Anatolia and northwestern Iran, northern Iraq, western Iran, the Caspian region and south Azerbaijan, and the Caucasian rim and southern Black Sea coast. In addition to these five main sections, the book contains an introduction written by the editors, and an appendix with comparative lists of lexical items from the languages treated in the book.
