The paper is devoted to semantic factors ruling differential object indexing (DOI) with clausal arguments in Moksha-Mordvin. Non-derived direct objects (DOs) in Moksha both exhibit differential object marking (DOM) and trigger DOI with transitive verbs. The choice between the constructions with and without object agreement markers is regulated by the factors largely discussed in the literature on DOM: referential properties of DOs, topicality and telicity of the verb (Comrie 1989; Aissen 2000; Tamm 2004). The omittance of object agreement is favored by presence of verbal derivational suffixes signaling non-telicity or pluractionality. However, in constructions with clausal DOs other factors come at play, such as factivity, semantic opposition of events (states-of-affairs) vs. propositions (Molnár 1971; Serdobolskaya, Kozhemyakina 2014).
