Nouns & co. Converging evidence in the analysis of associative plurals

Abstract A morphosyntactic peculiarity that separates proper names from (most) other noun types is their ability to occur in a special type of plural, called associative plural, whose meaning is X and X’s associated person(s). In this paper, we apply a ‘converging evidence’ methodology to the analysis of associative plurals, by providing a diachronic typology of these plurals through the identification of the more frequent sources of associative plural markers that are attested in a sample of 80 languages, and by looking for emerging constructions for the expression of associative plurality in two corpora of English and Italian, two languages that do not have a grammaticalized way to encode this type of plurality. The analysis will show that associative plurals are likely to grammaticalize from a restricted pool of synchronic sources, and that these sources are mostly indexical sources and sources denoting the plural set, in accordance with the special semantics and referential properties of proper names.
