Discursive system of Periodicity in an argumentative text

ABSTRACT

The discursive system of Periodicity, proposed by Martin (1992)Martin, J.R. (1992). Theme, method of development and existentiality: The price of reply. Occasional Papers in Systemic Linguistics, 6, 147-83. and by Martin and Rose (2007)Martin, J.R., & Rose, D. (2007). Working with discourse: meaning beyond the clause. Continuum. towards the analysis of discourse flow is based upon systemic functional linguistics (Halliday, 1967Halliday, M.A.K. (1967). Notes on transitivity and theme in English Part 2.

More precisely upon Hallidayan concepts of Theme and New information (New), in addition to concepts of thematic progression and hyperTheme (Daneš 1974Daneš, F. (1974).

Mouton de Gruyter.) as well as texts’ methods of development and point (Fries 1981Fries, P.H. (1981). On the status of theme in English: Arguments from discourse. Forum linguisticum, 6, 1-38. ; 1995Fries, P.H. (1995). Themes, Methods of Development, and Texts. In R. Hasan & P.H. Fries (Eds.), On Subject and theme: A discursive functional perspective (pp. 317-360). John Benjamins.). In this study we analyze how information flows in an argumentative text to verify the relationship between different levels Themes (hyperTheme and macroThemes) and the method of development as well as their relationship with text genre and the expression of a point of view. We also looked at the relationship between New clauses and macroTheme, which focuses on the expansion of ideational meaning around the field of the text and coincides with the Reiteration of the thesis stage. Results show a simple method of development marked by a Periodicity hierarchy in which smaller discourse units are structured within greater units.
