CasesystProg: Case marking is progressively asymmetrical; a limited group within nominals (such as pronouns) shows a greater number of cases than the majority of nominals.
(Onina 2009: 25, 30)
Nouns have three and pronouns have four cases in Synja Khanty. The accusative-dative form is expressed by the possessive affix for the personal pronouns, and the spatial case-markers are attached to this stem. The accusative form of nouns is identical with the nominative.
