This book represents the culmination of the author's work to date – it incorporates and updates previous articles and adds much new material. This book is not – nor was it ever intended to be – a comparative grammar of either the Indo-European or the Afroasiatic language families. It is, rather, a comparison of Proto-Indo-European with Proto-Afroasiatic. While this is not the first attempt to demonstrate that Proto-Indo-European and Proto-Afroasiatic are genetically related, it is the first to use the radical revision of the Proto-Indo-European consonantal system proposed by Thomas V. Gamkrelidze, Paul J. Hopper, and Vjaceslav V. Ivanov. Moreover, unlike previous endeavors, this is the first to make extensive use of data from the non-Semitic branches of Afroasiatic. The assumptions underlying this investigation of the possibility of the common genetic origin of Proto-Indo-European and Proto-Afroasiatic differ considerably from the assumptions made in other works on "Nostratic"; the methodological approach followed in this monograph has been one of rigorous adherence to the time-honored principles of comparative reconstruction.

A comprehensive summary of the Nostratic Hypothesis as of 2011, providing (1) the basis for the reconstruction of Proto-Nostratic as presented by Allan Bomhard, Vladislav M. Illič-Svityč, Aharon B. Dolgopolsky, Joseph H. Greenberg, and others; (2) a comparative vocabulary of Proto-Indo-European stems with proposed Nostratic etymologies and cognates from other branches of Nostratic; (3) a systematic evaluation of the material contained in Aharon Dolgopolsky¿s Nostratic Dictionary.

TRENDS IN LINGUISTICS is a series of books that open new perspectives in our understanding of language. The series publishes state-of-the-art work on core areas of linguistics across theoretical frameworks as well as studies that provide new insights by building bridges to neighbouring fields such as neuroscience and cognitive science. TRENDS IN LINGUISTICS considers itself a forum for cutting-edge research based on solid empirical data on language in its various manifestations, including sign languages. It regards linguistic variation in its synchronic and diachronic dimensions as well as in its social contexts as important sources of insight for a better understanding of the design of linguistic systems and the ecology and evolution of language. TRENDS IN LINGUISTICS publishes monographs and outstanding dissertations as well as edited volumes, which provide the opportunity to address controversial topics from different empirical and theoretical viewpoints. High quality standards are ensured through anonymous reviewing.

The “Nostratic” hypothesis — positing a common linguistic ancestor for a wide range of language families including Indo-European, Uralic, and Afro-Asiatic — has produced one of the most enduring and often intense controversies in linguistics. Overwhelmingly, though, both supporters of the hypothesis and those who reject it have not dealt directly with one another’s arguments. This volume brings together selected representatives of both sides, as well as a number of agnostic historical linguists, with the aim of examining the evidence for this particular hypothesis in the context of distant genetic relationships generally. The volume contains discussion of variants of the Nostratic hypothesis (A. Bomhard; J. Greenberg; A. Manaster-Ramer, K. Baertsch, K. Adams, & P. Michalove), the mathematics of chance in determining the relationships posited for Nostratic (R. Oswalt; D. Ringe), and the evidence from particular branches posited in Nostratic (L. Campbell; C. Hodge; A. Vovin), with responses and additional discussion by E. Hamp, B. Vine, W. Baxter and B. Comrie.
