This paper focuses on semantics and syntax of two attributivizers in Kazym Khanty. Both of the attributivizers have proprietive semantics and attach to a small nominal rather than a full DP. Proprietives are not completely interchangeable, therefore the difference between them is also explored in this paper. Moreover, we are going to show that both attributivizers significantly differ from cases. However, adjectives derived by proprietive markers differ from regular adjectives, as well.
