Costruzioni a schema fisso in alcune varietà diatopiche d'Italia. Prospettive teoriche e lessicografiche.

The paper is devoted to the analysis of partially lexically specified constructions in different diatopic varieties of Italian. These word combinations can be defined as constructions since they are pairings of form and meaning characterized by the presence of fixed and empty positions. The investigation examines examples of partially lexically specified (phrasal and sentence) constructions in Sardinian and in the regional Italian of Rome. The analysis shows that this combinatorial type is widespread within the national language as well as in local varieties. The phenomena which have been considered mainly concern: i) the presence of indigenous constructions in the local variety; ii) the presence of constructions modelled on the roof language; iii) the lexicalisation of forms in the local variety from roof language constructions, which radiate back as fixed sequences into the national language. The analysis also considers the lexicographic perspective and shows that these constructions are generally underrepresented in lexicographic tools, even though their single instantiations are often recorded in the corresponding entries.
