Corresponding Author Mazzaggio, Greta (greta.mazzaggio@unifi.it) Abstract This dataset consists of linguistic examples of Italian morphosyntactic microvariation documented in the three volumes: Manzini M.R., Savoia L.M. (2005), I dialetti italiani e romanci. Morfosintassi generativa, Alessandria, Edizioni dell’Orso.These data are also accessible from the following link: https://manzinisavoia.changes.unifi.it/ Dataset content The dataset consists of a corpus of linguistic examples illustrating microvariation in Italian dialects, compiled by Manzini and Savoia (2005). It includes data from 457 Italian dialectal varieties, 9 Corsican varieties, and 19 Swiss varieties, all collected through field research and annotated using the International Phonetic Alphabet (IPA). The corpus contains a total of 64,472 linguistic examples, each consisting of a dialectal sentence transcribed in IPA along with its Italian gloss. For each linguistic example, additional metadata is provided in the header line of the CSV file, using self-explanatory field names: Locality_official_name: Official name of the municipality or village. Locality_short: Shortened version of the municipality or village name. Chapter_title: Title of the chapter in Manzini & Savoia (2005) where the example appears. Chapter_subtitle: Title of the subchapter in Manzini & Savoia (2005) where the example appears (if applicable). Example: Dialectal sentence transcribed in IPA. Glossa: Italian gloss of the example. Data are in CSV format. For further information about data acquisition and digitization, please refer to the publication below. In order to correctly view the examples in IPA, it is essential to use a text editor or software that supports UTF-8 encoding. The dataset consists of a single file of approximately 3.5 MB.
