As it is well known from the literature, the conective pois works as a conjunction, sharing proprieties of both coordinator and subordinator, as an affirmation adverb and as a consequence adverb. Regarding its functioning at a pragmatic and discourse level, the analysis of this particle contributes to the discussion about the need for a natural class of discourse markers. The description of the functioning of pois as a discourse marker supports its integration in different categories. Some ideas on its diachronic path are evaluated considering data from two corpora of written letters (from the XVIth century to the XXth century).info:eu-repo/semantics/publishedVersio
