Exploring the form of Italian diminutives: Alternation patterns and constructional schemas

In this paper, we provide an extensive analysis of the formal features displayed by Italian diminutives (especially allomorphy) by using surface alternation patterns automatically extracted from a dataset of base-diminutive pairs. Applying the theoretical tools provided by Construction Morphology (CxM), we take alternation patterns as a proxy for paradigmatic relations and locate them into separate hierarchies, exploiting the mechanism of multiple inheritance in order to express generalizations on different, mutually independent factors at play (i.e., lexical category, gender and final segment of the base and derivative, suffixes and antesuffixal phonological material displayed by the derivative). In doing so, we contribute to the exploration of the formal side of Italian diminutives, which have been so far addressed mostly from a semantic perspective, and to the refinement of the representation of formal phenomena such as allomorphy according to the CxM framework.
