This article analyzes the functioning of the multifunctional discourse structuring pragmatic marker a prop & oacute;sito in Portuguese, considering the interface between text linguistics and functional linguistics. The research is based on the concept of sequential cohesion (F & aacute;vero,1991; Koch, 2018; Koch & Elias, 2018; Tavares, 2010) and on the postulates about multifunctional discourse structuring pragmatic markers (Traugott, 2022), in order to describe the multifunctional nature of this linguistic unit. For this purpose, 300 news texts were collected from the Corpus do Portugu & ecirc;s, of which 67 registered occurrences of a prop & oacute;sito functioning as a multifunctional discourse structuring pragmatic marker. The analysis, of both qualitative and quantitative character, found that this marker contributes to textual progression by performing retroactive-propulsive sequencing of information, articulating sentential statements and guiding the interlocutor's attention. The results also indicate that a prop & oacute;sito displays prototypical properties of multifunctional discourse structuring pragmatic markers, such as short length, detachment through punctuation, processing of semantic cues that aid interpretation, multifunctionality, non-truth-conditionality, lack of syntactic integration, and the presence of (inter)subjectivity, thus confirming its relevance as atextual-organizational and interactional resource. In thisway, the study highlights the importance of investigations that articulate different theoretical perspectives in the description of pragmatic elements that remain relatively underexplored.
