This paper raises the problem of clausal subjectivity and topicalisation in Siladang language. The nature of subjects refers to the links between an agent and its topic. Agents become the grammatical roles which are based on semantic roles, while topics are primarily concerned with pragmatic functions. The discussion of pragmatic functions is intended to find out whether the Bahasa Siladang is categorized as either the subject prominent language group or the topic prominent language. This study is based on the theoretical framework of language typology in regard with the difference between the language that accentuates the subjects with the language that accentuates the topics as what has been suggested by Li and Thompson (1976 (see Li (Ed.), 1976: 457-489).
