Construções causais e explicativas como estratégias discursivas em textos midiáticos

Abstract

This thesis presents, as object to analysis, causal and explicates constructions in Portuguese language. It aims, from a bibliographical research, to reflect upon the relations of cause and explanation, according to various approaches, such as Traditional Grammar, Discourse Semiotics and Argumentative Semantic. To study those constructions and to observe the linguistic and discursive aspects pointed out, a corpus of 85 texts from a newspaper opinion section was used, in order to verify the context in which syntactic structures are shown and what their function in discourse is. The method applied to compose the corpus was the selection of 27 texts written by Merval Pereira, published in O Globo, in País (Country) section. The collection of data was made from December 2015 to May 2016, a moment when the impeachment of President Dilma Rousseff was the highlight in all texts. The occurrences of causal and explicates constructions were analyzed according to: (i) the position in the statements; (ii) the possibility of displacement; (iii) verbs time and tense; (iv) the type of connector; (v) the presence of highlight structures; (vi) modality adverbs; (vii) the way discourse is organized (type of sequence); (viii) discourse genre. It was observed that those structures brought higher credibility to discourse and built distinct argumentative strategies
