Topic-strategies and the internal structure of nominal arguments in Greek and Italian

In this article, we argue that a set of unexpected contrasts in the interpretation of clitic-left-dislocated indefinites in Greek and Italian derive from structural variation in the nominal syntax of the two languages. Greek resists nonreferential indefinites in clitic left-dislocation, resorting to the topicalization of an often bare noun for nonreferential topics. By contrast, clitic left-dislocation is employed in Italian for topics regardless of their definite/indefinite interpretation. We argue that this contrast is directly linked to the wide availability of bare nouns in Greek, which stems from a structural difference in the nominal syntax of the two languages. In particular, we hypothesize that Greek nominal arguments lack a D layer. Rather, they are Number Phrases. We situate this analysis in the context of Chierchia’s (1998) typology of nominals. We argue that, on a par with Italian nouns, Greek nouns are [-arg, +pred]. However, they do not employ a syntactic head (D) for type-shifting to <e>. Rather, they resort to covert type-shifting, a hypothesis that is necessary to account for the distribution and interpretations of bare nouns in Greek, vis-à-vis other [-arg, +pred] languages like Italian and French.
