How could we define Gallurese? It is a Sardinian-Gallurese, a northern Sardinian with affinities in Sassari, Stintino, Sorso, Sedini etc. With minorities in Perfugas. At times in the modern age, groups of Corsican populations would cross the Strait of Bonifacio and settle in Gallura, which had been depopulated by wars. From then on, a kind of two-dimensional phenomenon would begin. On the one hand, Gallurese has gained more and more ground and number of speakers vis-à-vis Sardinian; on the other hand, while retaining a syntactic form foreign to the Sardinian language, it has conformed its lexicon to many expressions of Logudorese. In this way, it became today’s Gallurese, a language that cannot be considered not fully Sardinian, even if objective criteria of scientificity oblige to classify this idiom among the alloglot varieties.
