We are going to use the Corpus Linguistics as a methodology, since we are going to interpret some data like usage, frequency and clusters in order to assemble some statistic data and excel tables. The data source is in the academic Brazilian Portuguese Corpus, which encompasses some published materials such as books, course books, graduate and postgraduate journals. The purpose of this research is to demonstrate some current tendencies in the use of this phenomenon in academic writing: how, why and where it is used. Throughout this paper, we are going to study the phenomenon empirically, observing how syntax, semantics and pragmatics understand it in order to search for information to explain why this tendency occurs and what motivates its usage in academic Brazilian Portuguese / objetivo do trabalho ? evidenciar o fen?meno (de)que?sta no Portugu?s Brasileiro acad?mico. Utilizaremos a lingu?stica de corpus como metodologia, uma vez que interpretaremos dados como frequ?ncias de usos e agrupamentos lexicais para que montemos tabelas e gr?ficos estat?sticos. A fonte dos dados est? no Corpus do Portugu?s Acad?mico, que cont?m um apanhado de textos j? publicados como livros, materiais did?ticos, revistas de gradua??o e p?s-gradua??o. Uma das finalidades da pesquisa ? mostrar tend?ncias contempor?neas no uso do fen?meno na escrita acad?mica: como, porqu? e onde ele ? mais utilizado. No decorrer do trabalho, descreveremos o fen?meno de modo emp?rico, observando como a sintaxe, sem?ntica e a pragm?tica o entendem, a fim de buscar informa??es para explicar o porqu? dessa tend?ncia e motiva??o em L?ngua Portuguesa Brasileira Acad?mica
