Because Mandarin Chinese is a language without much morphology in case, number, and gender; i.e., an uninflectional analytical language in which word order plays a decisive role in determining the semantics of a sentence; it seems inconvenient to investigate the language in the framework of relational grammar (RG); which depends heavily on case marking. However, the universality of RG lies in the fact that the grammatical relationship between sentence elements exists in every natural language. While exploitation of case markers provides an effective access to the problem, RG offers other options for a language underdeveloped in case marking. The few case markings in Mandarin Chinese, for direct and indirect objects, can be combined with other syntactic devices such as passivization in a preliminary investigation of some Mandarin Chinese phenomena within the RG framework. An analysis of Mandarin Chinese intransitive sentences illustrates this possibility. (Author/MSE)
