Question: Casu modde, casu cundídu and casu fràzigu , translated to English means "rotten/putrid cheese", is what  primary indigenous Romance language spoken on most of the island of Sardinia ?

full_context: Document 1: Italian language: Italian (   ] or "lingua italiana" ] ) is a Romance language. By most measures, Italian, together with Sardinian, is the closest to Latin of the Romance languages.
Document 2: Sicilian language: 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.
Document 3: Catalan language: Catalan ( ; autonym: "català" ] ] ) is a Romance language derived from Vulgar Latin and named after the medieval Principality of Catalonia, in northeastern modern Spain. It is the national and only official language of Andorra, and a co-official language of the Spanish autonomous communities of Catalonia, the Balearic Islands and Valencia (where the language is known as Valencian). It also has semi-official status in the Italian commune of Alghero. These territories are often called Catalan Countries.
Document 4: Vulgar Latin: Vulgar Latin or Sermo Vulgaris ("common speech") was the nonstandard form(s) of Latin (as opposed to "classical") spoken in the Mediterranean region during and after classical period of the Roman Empire. It is from Vulgar Latin that the Romance languages developed; the best known are the national languages Italian, Spanish, Portuguese, Romanian, and French. Works written in Latin during classical times and the earlier Middle Ages used Classical Latin rather than Vulgar Latin, with very few exceptions (most notably sections of Gaius Petronius' "Satyricon"). Because of its nonstandard nature, Vulgar Latin had no official orthography. Vulgar Latin is sometimes also called colloquial Latin, or Common Romance (particularly in the late stage). In Renaissance Latin, Vulgar Latin was called "vulgare Latinum" or "Latinum vulgare."
Document 5: Saint-André cheese: Saint-André is a brand of French triple crème cow's milk cheese with a powdery white, bloomy skin of mold, in the form of a 200 g cylinder, 6 cm in diameter and 5 cm high. Originally developed and manufactured by the Soulié cheese factory in Villefranche-de-Rouergue, Aveyron, it is now produced in Vire, Calvados. It has a soft buttery texture, tangy edible rind, and tastes like an intense version of Brie. Cream is added to the cheese during manufacture, and the curing process lasts approximately 30 days.
Document 6: Weisslacker: Weisslacker (German for "whitewashed" due to the rind color), also known as bierkäse and beer cheese, is a type of cow's milk cheese that originated in Germany, but is now known worldwide. Also produced in the United States, mostly in Wisconsin, it is a pungent and salted surface-ripened cheese that starts out much like brick cheese. It ripens for seven months in highly humid conditions and is related to Limburger cheese, and has a similarly powerful smell, but paradoxically mild taste. Connoisseurs of this delicacy often take it with beer (sometimes dipping the cheese directly in their drinks), hence the name. Many find it too overpowering to serve with wine. This cheese is also served on small slices of rye or pumpernickel bread often with some sliced onion. It is a common item on pub and restaurant menus in the Czech Republic, the country with the highest per-capita beer consumption in the world. This cheese is a common ingredient in various breads, soups, and dips.
Document 7: Casu marzu: 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".
Document 8: Sardinia: Sardinia ( ; Italian: "Sardegna" ] , Sardinian: "Sardìgna/Sardìnnia" ] /] , Sassarese: "Sardhigna", Gallurese: "Saldigna", Catalan: "Sardenya", Tabarchino: "Sardegna") is the second largest island in the Mediterranean Sea (after Sicily and before Cyprus) and an autonomous region of Italy. It is located in the Western Mediterranean, to the immediate south of the French island of Corsica.
Document 9: Coda di Pecora: Coda di Pecora is a white Italian wine grape variety that is grown in the Campania region of southern Italy, particularly in the province of Caserta. The name "Coda di Pecora" means "goat's tail" in the local dialect and for many years was thought to be a clonal variation of another white Campanian variety, Coda di Volpe, whose name means "foxtail".
Document 10: Ligurian (Romance language): 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.
Document 11: Corsican language: 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.
Document 12: Brânză de burduf: Brânză de burduf is a salty type of cheese, made with sheep (or occasionally buffalo) milk. It has a strong flavour and slightly soft in texture. To obtain it, sweet caş is cut into small pieces, salted and then hand-mixed in a large wooden bowl. The mixture is then placed in a sheep’s stomach, or into a sheep’s skin that has been carefully cleaned and sawed on the edges, or in a tube made of pine bark. The cheese can be consumed even if kept for a long time in a sheep’s stomach or in a sheep’s skin. If kept in pine bark, the cheese gets a specific pine resin flavour. The cheese is specific to southeastern Transylvania, Romania.
Document 13: Casín cheese: Casín cheese (Spanish: "queso Casin" )is a Spanish cheese made in the Principality of Asturias. Its name is covered by a protected designation of origin (PDO). It is made from full-fat, unpasteurized cows' milk from specific breeds, namely Asturian Mountain ("Asturiana de la Montaña", a.k.a. Casina), Asturian Valley "(Asturiana de la Valles"), Friesian and any crosses between these breeds. Specifically the geographic area of manufacture is the southern part of Asturias which includes the Redes Natural Park ("Parque Natural de Rede"s) and associated land, this is within the municipalities of Caso, Sobrescobio and Piloña. The cheese is classified as hard and semi-hard, and can be semi-cured or cured. It takes its name from one of the breeds of cattle whose milk is used, in turn named after the town of Caso.
Document 14: Sardinian language: 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.
Document 15: Caravane cheese: Caravane is the brand name of a camel milk cheese produced in Mauritania by Tiviski, a company founded by Nancy Abeiderrhamane in 1987. The milk used to make the cheese is collected from the local animals of a thousand nomadic herdsmen, is very difficult to produce, and yields a product that is low in lactose. As Mauritanians do not generally eat cheese, and the European Commission has not yet fully implemented policies designed for dromedary milk products, Caravane is difficult to find in Europe. Its availability is largely limited to Nouakchott shops and restaurants, and as an export to neighboring Senegal. It can now be purchased in select stores in New York.
