In Surgut Khanty, the core cases are syncretistic, as the subject, the object and the possessive adjunct all take the nominative case (1)–(3). The personal pronouns have distinct accusative (2) and dative (5) forms. The dative is missing from the noun case-marking paradigm, and it is substituted by the lative -a or the approximative -nam (4) suffixes.
