Sardinian ("sardu", "limba sarda", "lingua sarda") or Sard is the primary indigenous Romance language spoken on most of the island of Sardinia (Italy).
 Among the Romance languages, it is considered one of the closest genealogical descendants, if not the closest, to Latin.
 However, it also incorporates a Pre-Latin (Paleo-Sardinian, also known as Nuragic, and, to a much lesser degree, Punic) substratum, and a Byzantine Greek, Catalan, Spanish and Italian superstratum due to the past political membership of the island, first falling into the Hispanic sphere of influence and later towards the Italian one.
The Occitans (Occitan: "los occitans" ) are an indigenous Romance language speaking ethnic group, originating in Occitania (southern France, northeastern Spain and northwestern Italy).
Sicilian ("sicilianu" ; in Italian: "Siciliano"; also known as Siculo ("siculu" ) or Calabro-Sicilian) is a Romance language spoken on the island of Sicily and its satellite islands.
 It is also spoken in southern and central Calabria (where it is called Southern Calabro), in the southern parts of Apulia, Salento (where it is known as Salentino), and Campania, on the Italian peninsula, where it is called Cilentano (Gordon, 2005).
 The "Ethnologue" (see below for more detail) describes Sicilian as being "distinct enough from Standard Italian to be considered a separate language" (Gordon) and is recognized as a "minority language" by UNESCO.
 Some assert that Sicilian represents the oldest Romance language derived from Vulgar Latin, but this is not a widely held view amongst linguists and is sometimes strongly criticized.
 Sicilian has the oldest literary tradition of the Italic languages.
Venetian or Venetan (Venetian: "vèneto ", "vènet " or "łéngua vèneta ") is a Romance language spoken as a native language by almost four million people in the northeast of Italy, mostly in the Veneto region of Italy, where most of the five million inhabitants can understand it.
 It is sometimes spoken and often well understood outside Veneto, in Trentino, Friuli, Venezia Giulia, Istria, and some towns of Dalmatia, Slovenia, Croatia and Brazil.
Dalmatian or Dalmatic was a Romance language spoken in the Dalmatia region of Croatia, and as far south as Kotor in Montenegro.
 The name refers to a tribe of the Illyrian linguistic group, Dalmatae.
 The Ragusan dialect of Dalmatian was the official language of the Republic of Ragusa, though in later times Venetian (representing the Romance language population), then Eastern Herzegovinian dialect of Serbo-Croatian (for the Slavophone population) came to supersede it.
Corsican ("corsu" or "lingua corsa") is a Romance language within the Italo-Dalmatian subfamily.
 It is closely related to the Italian language and especially to its Tuscan branch.
 It is spoken and written on the islands of Corsica (France) and northern Sardinia (Italy).
 Corsican was long the vernacular alongside Italian, the official language in Corsica until 1859; afterwards Italian was replaced by French, owing to the acquisition of the island by France from the Republic of Genoa in 1768.
 Over the next two centuries, the use of French grew to the extent that, by the Liberation in 1945, all islanders had a working knowledge of French.
 The 20th century saw a wholesale language shift, with islanders changing their language practices to the extent that there were no monolingual Corsican speakers left by the 1960s.
 By 1995, an estimated 65 percent of islanders had some degree of proficiency in Corsican, and a small minority, perhaps 10 percent, used Corsican as a first language.
Casu marzu (] , also called casu modde, casu cundídu and casu fràzigu in Sardinian language), literally translating into English as "rotten/putrid cheese", is a traditional Sardinian sheep milk cheese, that contains live insect larvae (maggots).
 Although found in the island of Sardinia, a variety of this cheese is also found on the nearby island of Corsica, where it goes by the name of "casgiu merzu".
Asturian ( ; autonym: "asturianu" ] ,<ref name="bable/asturiano">Art. 1 de la Ley 1/1998, de 23 de marzo, de uso y promoción del bable/asturiano/Law 1/93, of March 23, on the Use and Promotion of the Asturian Language</ref> formerly also known as "bable" ] ) is a West Iberian Romance language spoken in Principality of Asturias, Spain.
 Asturian is part of a wider linguistic group, the Astur-Leonese languages.
 The number of speakers is estimated at 100,000 (native) and 450,000 (second language).
 There are three main variants in the Astur-Leonese language family: Western, Central, and Eastern.
 For historical and demographic reasons, the standard is based on Central Asturian.
 Asturian has a distinct grammar, dictionary, and orthography.
 Regulated by the Academy of the Asturian Language, although it is not an official language of Spain it is protected under the Statute of Autonomy and is an elective language in schools.
Ligurian ("ligure" or "lengua ligure") is a Gallo-Italic language spoken in Liguria in Northern Italy, parts of the Mediterranean coastal zone of France, Monaco and in the villages of Carloforte and Calasetta in Sardinia.
 It is part of the Western Romance language continuum.
 The Genoese ("Zeneize"), spoken in Genoa, the capital of Liguria, is the language's prestige dialect on which the standard is based.
Vastese (Vastese: "Lu Uâʃtaréule" or "Lu indialett di lu Uašt", meaning "the dialect of Vasto") is a Romance language spoken in the town of Vasto.
 It is considered its own language based upon the mutual unintelligibility of it and Italian.
 It is not spoken by any other town, even the nearby town of Cupello, which is only 9 km away.
