A aferição da modalidade epistêmica em enunciados sob escopo de advérbios de dúvida

Abstract

Following the perspective of Sociolinguistics Variationist, we conceive the variation inherent in the linguistic system. We evaluated the frequency of alternation subjunctive/indicative in doubters sentences in speaking community of Mexico City and by hypothesis we assume that the mode is a factor conditioning this alternation. In this way, this work appears as an analytical essay of a discourse-pragmatic category confrontational mode. The basic objective of this work is to seek to formalize parameters for the measurement of epistemic irrealis modality understandable in speech. In this sense, conceiving his influence as a factor conditioning the alternation subjunctive/indicative in doubters non-subordinated sentences we can evaluate its performance, in terms of Labov (1972), as an independent variable.
