Numerals of Second Ten in Languages of Siberia

The article discusses models of formation of second ten numerals (11 to 19) in the languages of Siberia. The "simple" model, where numerals are formed by adding the number of units to "ten" ("ten one", "ten two", etc.), is characteristic of the languages of southern Siberia, and also penetrates to the north, east of the Yenisei and east of Yakutia. The second model, which includes a word like "surplus", is widespread in the northern part of Siberia, from its western to eastern borders. The remaining models are represented by few languages each: these are locative ("at ten one"), ablative ("from ten one"), comitative ("with ten one") and their combinations with the word "surplus", as well as constructions such as "second ten one" and "to twenty one". The latter model corresponds with the language of the ancient Orkhon-Yenisei monument
