Constructing lists to construct categories

Abstract

The aim of this paper is to analyze list constructions as linguistic tools to build categories in discourse, identifying the inferential processes leading from list constructions to categorization and examining the semantic and morphosyntactic elements that activate abstractive reasoning within lists. Based on real occurrences of lists in written and spoken Italian, we will first of all propose a crucial distinction between exhaustive and non-exhaustive lists, arguing that (non-)exhaustivity determines the layer at which the construction of a category occurs, namely the layer of presupposition or the ‘what-is-said’ part of the utterance. We will then focus on non-exhaustive lists, arguing that they directly communicate a bottom-up, exemplar-driven abstraction, characterized by the presence of an inherently indexical reference (i.e. reference to further Xs characterized by some underlying Property P), which will lead us to call it ‘indexical categorization’. The linguistic analysis of how indexical categorization is expressed in discourse will show a major distinction between (i) elements characterized by an indexical semantics, which trigger the abstraction process, and (ii) elements providing semantic clues towards the correct construction of the indexical category. We will conclude by taking a broader perspective and by explaining the patterns observed for indexical categorization in the light of the wider process of online reference construction
