The comparative analysis of the variation observed in the nominal domain across the dialects of Italy is based on the parameter system used in Ceolin et al (2021) and on (a slightly updated version of) the questionnaire described in Crisma, Guardiano and Longobardi (2020) and Crisma et al (2024).

So far (May 2026), data have been collected from the languages shown in the map below. A table with detailed information about glottocodes, isocodes, language groups, geographical locations and coordinates can be found at the bottom of this page.
