Gallurese (gadduresu) is a Romance dialect of the Italo-Dalmatian family spoken in the region of Gallura, northeastern Sardinia. Gallurese is variously described as a distinct southern dialect of Corsican or transitional language of the dialect continuum between Corsican and Sardinian. "Gallurese International Day" (Ciurrata Internaziunali di la Linga Gadduresa) takes place each year in Palau (Sardinia) with the participation of orators from other areas, including Corsica.
Gallurese is generally considered a southern Corsican dialect, sharing close resemblance in morphology and vocabulary with the dialects of Sartene and Porto-Vecchio on Corsica, whereas its phonology and syntax are similar to those of Sardinian. One third of Gallurese vocabulary is also influenced by Logudorese Sardinian, Catalan, and Spanish.
