Neutr: Case alignment is neutral: the functions S, A, and P are not marked morphologically.
NoPMark: The function P is not explicitly marked, while S, A, or both are marked. P is therefore marked with a zero (∅) morpheme.
PAff: The function P is marked with affixation.

In Surgut Khanty, if the P is a noun, it is not marked morphologically, thus the S, the A, and the P functions are coded neutrally (1a). The same can be observed in the case of non-personal pronouns e.g. determiners (1b), and interrogative pronouns (1c). Personal pronouns have accusative forms, hence the PAff value is valid here (1d). In passive constructions, the A is marked with a locative suffix and the P takes the nominative case. Non-personal (2a) and personal pronouns (2b) behave the same way in passive constructions (thus the NoPMark parameter value applies).
