“…Various approaches have been developed throughout the history of discourse words studies, among which the following can be mentioned: -Discourse-words based approaches to discourse theory (Ducrot, 1969(Ducrot, , 1973(Ducrot, ,1976(Ducrot, , 1977(Ducrot, , 1980a(Ducrot, , 1985Ducrot & Anscombre 1980, 1983 or utterance value (Nemo, 1992(Nemo, , 1996(Nemo, , 1999a; -Relevance-based approaches of DWs (Blakemore, 1987;Luscher 1994, Rouchota) -Discourse-based approaches of DWs (Schiffrin, 1987;DRT) -Speech-act based approaches of DWs (Fraser, 1987(Fraser, , 1996(Fraser, , 1998 -Distribution-based approaches of DWs (Rossari, 1993;Jayez & Rossari, 1996) The main differences among those approaches is: 1) the way they consider discourse words function: -In Ducrot's first models DWs' function is to indicate the functions of the utterances connected. DWs are described in instructional terms; -RT models, built explicitly (Wilson & Sperber, 1990, 1993) on a procedural renaming of Ducrot's instructions, see DWs as a guide for utterance interpretation (Lusher, 1994); -Speech-act based approaches consider that DWs have a connective function, and that their meaning is what is done when using a DW.…”
