The paper discusses the syntax of postpositional constructions in Meadow Mari (Uralic, Morkinsko-Sernur dialect;
head-final, SOV). Building upon existing approaches to postpositions in the world’s languages, I propose that PPs in Mari may have
one of two underlying structures depending on the nature of the dependent but not on the nature of the adposition. PPs with a
pronominal dependent involve possession between the Ground and a location nominal. In PPs with a non-pronominal dependent
the Ground is merged directly into the complement position of a P head. I further expand the dataset and show that the two
configurations successfully capture the distribution of reflexive pronouns in PPs. The proposed analysis accounts for all the
relevant data: examples with independent and affixal postpositions and referential and pronominal dependents.
