Abstract

Objectives The purpose of this study is to explicitly show how the hierarchy of periodicity in Korean texts is ana-lyzed based on Systemic Functional Linguistics.
 Methods The hierarchy of periodicity is viewed as having an expanding structure, like the flow of water, which expands into small waves, large waves, and tidal waves. It is explained that when the flow of text expands from clause to paragraph (→ chapter → text), it does not continue in a straight line, but expands like a wave in a circle. Assuming that this hierarchy of periodicity has genre differences, this paper analyzed the text of political news-paper articles related to the ‘Itaewon tragedy’ in written language and the text of parliamentary meeting related to the ‘Itaewon tragedy’ in spoken language.
 Results In terms of the hierarchical structure of the periodical, the newspaper article and the meeting showed different characteristics. The newspaper article (Text-I) was relatively well organized and followed the typical hi-erarchical structure of a periodical. In particular, it showed that it faithfully followed the structure of HyperTheme - (Elaboration) - HyperNew, which is necessary to organize paragraphs (paragraphs). It also followed the structure of MacroTheme - (Paragraph) - MacroNew when organizing units larger than paragraphs. The meeting text, on the other hand, shows a weak hierarchy, as the MacroTheme is sometimes omitted, and when organizing para-graphs, the HyperNew following the HyperTheme is omitted before moving on to the next topic, the MacroTheme.
 Conclusions This paper introduced the concepts of hierarchy of periodic words and serial word expansion of dis-course as two double-headed wagons for studying discourse meaning. I hope this article to be useful for future research on periodicity in Korean texts of various genres, as it demonstrates how to analyze discourse at the para-graph and text level beyond the analysis of ‘clause’ units, and examines the genre differences between them.
