Acesso em: 24 abr. 2023.e- 2238-935X1808-835Xhttp://repositorio.bc.ufg.br/handle/ri/22481This article describes the process of constituting the microconstruction “pois não” in the perspective of the Construction Grammar. It was verified that the syntactic-semantic changes run along a path that starts from an atypical context in which the construction “pois” ceases to act as a conjunction. In the critical context “pois” loses its conclusive function and assumes discursivepragmatic function. Finally, it reaches the isolated context: there are loss of the semantic function of the negation and the chunking between “pois” and “não”, resulting in innovative use, a new node in the network of discursive markers, a process of expansion.porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Gramática de construçõesMudançaPortuguês brasileiro“Pois não”Grammar of constructionsChangeBrazilian portugueseArtigohttp://dx.doi.org/10.31513/linguistica.2018.v14n1a15409
