Acesso em: 24 abr. 2023.e- 2359-6910http://repositorio.bc.ufg.br/handle/ri/22489This article aims to describe and analyse the microconstruction “um belo dia” ("a beautiful day") from the theoretical perspective of Usage-Based Functional Linguistics. The analysis is guided by the hypothesis that in Brazilian Portuguese the uses of microconstruction "um belo dia” (“a beautiful day") constitute a process of change, since it expresses linguistically a more concrete concept, it is active in the basic sentence organization and also configures a more abstract use, at the textual level, at the macro-organization of the narrative. The dates integrates the “Corpus do Português”, “Projeto Fala Goiana” and “Grupo Discurso e Gramática”. The analysis is in panchronic orientation.porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Linguística funcional centrada no usoGramática de construções“Um belo dia”Mudança construcionalPerspectiva pancrônicaUsage based linguisticsConstruction grammarConstructional changeArtigohttps://doi.org/10.24206/lh.v5i⒈15395
