2. Prefixation Ability Index (PAI) allows us to see whether two languages can potentially be genetically related
2.3.1. PAI against Nostratic hypothesis

Оглавление

Basing on comparison of lexis adepts of Nostratic hypothesis state that Indo-European stock, Kartvelian stock, Uralic stock and Turkic stock are relatives. Let’s see and test whether, for instance, Indo-European and Turkic stocks could be relatives.


PAI of Indo-European is about 0.5 (calculated after data represented in 2.1.4.2);


PAI of Turkic stock is about 0.012 (calculated after Yazyki mira. Tyurkskiye yazyki 1996).


Values of PAI differ more than tenfolds so these stocks evidently can’t be genetically related.
