Abstract: This chapter addresses other linguistic issues often utilized in the Indo-European homeland quest and in examining Indo-Aryan origins. It looks at the center of origin method (the arguments of Robert Latham, Lachhmi Dhar, and others), dialectical subgroupings of the various cognate languages and their implications (Gamkrelidze and Ivanov’s model and Koenraad Elst’s co-option of this), and Johanna Nichol’s Bactria-Sogdiana (east of the Caspian Sea) model. The basic thrust of this chapter and the previous two has been to demonstrate some of the problems that have arisen in an attempt to pinpoint the origins of the Indo-Europeans and their offshoot Indo-Aryans through linguistic methods. The next three chapters look at the archaeological evidence.

Keywords: dialectical subgroupings, Gamkrelidze and Ivanov’s model, Indo-Aryan origins, Indo-European homeland, Indo-European origins, linguistic evidence, Nichol’s Bactria-Sogdiana model, South Asian Indo-European homeland,
