Thematic Structure and Para-Syntax: Arabic as a Case Study presents a structural analysis of Arabic, providing an alternative to the traditional notions of theme and rheme. Taking Arabic as a case study, this book claims that approaches to thematic structure propounded in universalist linguistic theories, of which Hallidayan systemic functional linguistics is taken as an illustrative example, are profoundly wrong. It argues that in order to produce an analysis of thematic structure and similar phenomena which is not undermined by its own theoretical presuppositions, it is necessary to remove such notions from the domain of linguistic and semiotic theory. The book initially focuses on Sudanese Arabic, because this allows for a beautifully clear exposition of general principles, before applying these principles to Modern Standard Arabic, and some other Arabic varieties. This book will be of interest to scholars in Arabic linguistics, linguistic theory, and information structure.
