Аннотация:The classification of Samoyedic languages has become one of the most popular topics in Uralisticsin recent years, with at least six different perspectives expressed by leading experts, often in contradiction withone another. On the LingvoDoc platform, there are 16 dictionaries and concordances of texts in Samoyediclanguages. Among these, 10 dictionaries – Nenets, Enets, Nganasan, and Selkup dialects – were compiled fromnative speakers, while six others were derived from archival and published sources. They are analyzed usingthe glottochronology formula developed by S.A. Starostin. The analysis on LingvoDoc results in a 3D graphthat depicts the degree of temporal proximity regarding the divergence of Samoyedic languages and dialects. Itwas determined that, from a glottochronological perspective, there was a certain proximity between Nenets,Enets, and Nganasan, that are traditionally grouped into the North Samoyedic cluster, while Selkup, Mator, andKamasin, are regarded as South Samoyedic. However, these commonalities existed for a relatively short period.A longer period of unity was observed between Mator and Kamasin languages and between Nenets and Enets.The highest number of words with no etymology in other lists of basic vocabulary was found in Selkup dialectsand in the Nganasan language, indicating their prolonged isolated existence. The analysis conducted in thisstudy supports the validity of the traditional classification of Samoyedic languages. Considering the materialfrom early Selkup texts provides more reliable evidence for postulating the South Samoyedic group.
