A common ancestor of Indo-European and Hurrian
There is an interesting monograph by Fournet & Bomhard on the Indo-European Elements in Hurrian (pdf). I will leave the linguistic details to the experts, as I doubt that many people are competent in both Proto-Indo-European and Hurrian to assess the authors’ thesis. However, this is the bit that captured my attention:
Hurrian cannot be considered an Indo-European language — this is so obvious that it barely needs to be stated. Traditional Indo-European languages, such as Sanskrit, Greek, Latin, Gothic, Old Irish, Old Church Slavic, Tocharian, etc., are clearly related to each other through many common features and shared innovations that are lacking in Hurrian. However, that is not the end of the argument. In the preceding chapters, we presented evidence that Hurrian and Proto-Indo-European “[bear] a stronger affinity, both in the roots of verbs and in the forms of grammar, than could have been produced by accident; so strong that no philologer could examine [them] without believing them to have sprung from some common source.” In this chapter, we will discuss our views on what that common source may have been like. In so doing, we will have to delve deeply into prehistory, well beyond the horizon of what is traditionally reconstructed for Proto-Indo-European in the traditional handbooks. …
Our discussion now comes to an end. In the course of this book, we have attempted to show, through a careful analysis of the relevant phonological, morphological, and lexical data, that Urarto-Hurrian and Indo-European are, in fact, genetically related at a very deep level, as we indicated at the beginning of this chapter by quoting from the famous Third Anniversary Discourse (1786) of Sir William Jones. We propose that both are descended from a common ancestor, which may be called “Proto-Asianic”, to revive an old, but not forgotten, term.
On the basis of genetic data I have recently proposed an origin of the Indo-Aryans in the Transcaucasus, based on their possession of a genetic component related to that of modern Northeast Caucasian speakers and the putative relationship of the latter with the Hurro-Urartian group. If the Hurrian-Indo-European “Proto-Asianic” hypothesis is true, then it would strengthen that hypothesis as it would place the Proto-Indo-Europeans in the vicinity of the Hurrians.
