A new approach to the Indo-European classification: phonetic-semantic reconstruction of basic lexical units for intermediate original language states[Новый Подход К Индоевропейской Классификации: Фонетико-Семантическая Реконструкция Базисных Лексических Единиц Для Промежуточных Праязыковых Состояний]

This preprint suggests the reconstruction of Indo-European phylogeny based on thirteen 110-word lists for the proto-languages ​​of the IE subgroups (Proto-German, Proto-Slavonic, etc.) or the ancient languages ​​of the corresponding subgroups (Hittite, Ancient Greek, etc.). We use more or less formal methods for the collection of linguistic data and subsequent processing (semantic reconstruction, derivational drift elimination, optimization of homoplasias) recently proposed or developed for this study. We use a consistent phylogenetic procedure and obtain a consensus tree based on several algorithms (Bayesian analysis, maximum economy, joining of neighbors, lack of application of topological restrictions). The obtained tree topology and dating are fully compatible with the traditional views of experts. Our main finding is the multifurcation of the internal clade AI into four branches approx. 3357-2162 BC: (1) Greek-Armenian, (2) Albanian, (3) Italo-Germanic-Celtic, (4) Balto-Slavic-Indo-Iranian. The proposed scenario of discrepancy reconciles with each other the different opinions on the internal AI branching expressed earlier by the Indo-Europeists.
