In Synja Khanty, if the complement of the postposition is a noun, the postposition is only marked for case (1). If, however, the complement is a pronoun, the postposition takes a personal affix and a case ending (2), (3) (Honti 1984: 80‒82, Onina 2009: 48‒49). Thus, the postposition cannot take a personal affix if its complement is a noun.
