Resumen de The diachronic evolution of Italian 'mica': discourse strategies and language change
The paper studies the diachronic development of the Italian particle 'mica' from a usage-based perspective. Mica originates in a free noun denoting a small quantity (Latin 'MICA' (M) ‘crumb’), developed into a negation particle and, as claimed in this paper, into a pragmatic particle.The aim of the paper is twofold. First, it deals with the question in which contexts the shift from one use to another may have occurred and which discursive elements may have motivated the change.The analysis is based on the hypothesis that the change is triggered by rhetorical strategies of the speaker which sediment into new meaning components. The paper tries to provide evidence for this hypothesis with reference to historical data as well as an analysis of the discourse functions of mica in present-day Italian. The second aim of the paper is to show that, contrary to what has been claimed in previous studies, the use of mica has developed in a way that is quite different from the development described in a negation cycle. Its evolution appears to go beyond the process of grammaticalization as a negation marker. The paper argues that mica did not only turn from a lexical into a grammatical item, but – more interestingly – that the negation particle further developed into a pragmatic particle. The latter is characterized by particular discourse functions and can be more specifically described as modal particle
