This issue of Catalan Journal of Linguistics contains a selection of nine contribu-tions that were presented at the workshop “Nominal inflection and word-formation at the phonology-morphology interface” (NoWPhoMo), which took place in early 2024 at the Universitat de Barcelona (January 25) and at the Universitat Autònoma de Barcelona (January 26), as part of the coordinated research project Native and non-native phonology: Language contact effects and interaction with other com-ponents of grammar, PID2020-113971GB-C21 and PID2020-113971GB-C22. The edition of the volume was handled by project PID2020-113971GB-C22.

The contributions in this volume collectively address several persistent challenges in the analysis of partitivity, such as (i) the semantic underspecification of partitive markers, which are not always transparently associated with the part–whole relation; (ii) the connection between partitive markers and indefiniteness and negation; (iii) the diachronic development of partitive markers and their relation to other categories, such as determiners and prepositions; and (iv) the syntactic structure of binominal constructions. Overall, we hope that these contributions advance our understanding of the many empirical and theoretical problems that partitivity poses for linguistic theory.
