This paper will examine one of the most characteristic syntactic properties of languages, namely the case system for the following three Sinitic languages spoken in Northwestern China: Línxià (or Hézhōu), Tāngwāng, Gāngōu, which have been sometimes viewed as ‘mixed languages’. An answer to the following main questions will be tentatively suggested in the conclusion: do we really have case suffixes in these languages (cases are a morphological notion) or simply thematic roles expressed by postpositions (thematic roles are a semantic notion)? Do we really have a Qinghai-Gansu linguistic area (Sprachbund), as has been suggested? Can these Sinitic languages be characterized as being mixed languages?
