“…The theoretical background is based on the Systemic Functional Grammar (SFL), developed by Michael Halliday (HALLIDAY, 1973, 1978, 1985, 1992b, 1993HALLIDAY & MATTHIESSEN, 1999;HALLIDAY & MATTHIESSEN, 2004) and followers (EGGINS, 1994;MARTIN, MATTHIESSEN & PAINTER, 1997;THOMPSON, 1996THOMPSON, , 2004. SFL explains how language is structured as a semiotic system in different social contexts (EGGINS, 1994, p. 22-23), and sees it as a meaningmaking device deeply related to the social context around it (THOMPSON, 1998, p. 30).…”
