MATERIALS ON TOPONYMY OF THE KET OB REGION AS A BASIS FOR IDENTIFICATION OF THE SETTLEMENT BORDER OF THE <i>ŠÖŠQUM</i> / <i>ŠÖŠQUP </i>DIALECT LOCAL GROUPAND CONFIRMATION OF THE INTERMEDIATE POSITIONOF THE MIDDLE OB (SHESHKUM / SHESHKUP) DIALECT OF THE SELKUP LANGUAGE
This paper is devoted to the analysis of the toponymic materials recorded in the indigenous territory of the ethnographic (dialect local) group of Sheshkums/Sheshkups of the Ob River and its peripheral territory. In the course of our study, the toponymic material collected by researchers in the Ket Ob region was generalised, and the linguistic analysis of the identified toponyms was carried out in accordance with the peculiarities of the Central and Southern dialects; the distribution areas of these peculiarities were outlined. All the toponyms in Selkup were correlated with their Russian names. In the course of the analysis of all toponymic materials, two tables and one map were compiled. The first table demonstrates the Central and Southern peculiarities reflected in the toponyms of the Sheshkums/Sheshkups of the river Ob and the toponyms recorded in neighbouring settlements included in the area peripheral to the settlement territory of the Sheshkums / Sheshkups. The second table shows the interrelation of toponyms recorded by linguists and ethnographers in Selkup and Russian (1952-2019). All the Selkup toponyms that were found were marked on the map using the principle of the presence of Central and Southern dialectological features in them. Having compared the official toponymic data and the materials collected from the old-timer Selkups and Russian fishermen, it was revealed that there are significant differences in the official names and the names used by locals. That is why a large number of toponyms did not enter the map.
