Diferentes efeitos de exaustividade em clivadas: um estudo descritivo de casos

In this article, we show that cleft sentences may have ‘exhaustiveness effects’ quite different from the ‘identification by exclusion’ – which is the effect usually discussed by the literature (ATLAS; LEVINSON, 1981; HORN, 1981; KISS, 1998; WEDGWOOD; PETHO; CANN, 2006; BURING; KRIZ, 2013). To show this, we present a detailed study of cases in which we test the contextual effects triggered by clefts found in Brazilian magazines and newspapers. Our testing tools are modifiers that the literature associates with exhaustiveness, such as ‘only’ and ‘and nobody else’ (ATLAS; LEVINSON, 1981; HORN, 1981), and ‘exactly’ and ‘precisely’ (MENUZZI; ROISENBERG, 2010a). On the basis of such tests, we conclude that ‘exhaustiveness effects’ involve various types of inferences about the structure of the domain of the discourse referents, and may modify such a structure in many different ways. We believe this result puts into a new perspective many of the questions about the semantics and the pragmatics of clefts, in particular whether ‘exhaustiveness effects’ are conventionalized pragmatic inferences (such as a presupposition, or a generalized implicature), or particularized implicatures.
