Gallo-Italic languages

The Gallo-Italic, Gallo-Italian, Gallo-Cisalpine or simply Cisalpine languages constitute the majority of the Romance languages of northern Italy: Piedmontese, Lombard, Emilian, Ligurian, and Romagnol. In central Italy they are spoken in the northern Marches (Gallo-Italic of the Marches); in southern Italy in some language islands in Basilicata (Gallo-Italic of Basilicata) and Sicily (Gallo-Italic of Sicily).
Although most publications define Venetian as part of the Italo-Dalmatian branch, both Ethnologue and Glottolog group it into the Gallo-Italic languages.
The languages are spoken also in the departement of Alpes-Maritimes in France and in Ticino and southern Grisons, both in Switzerland, and the microstates of Monaco and San Marino. They are still spoken to some extent by the Italian diaspora in countries with Italian immigrant communities.
Having a Celtic substratum and a Germanic, mostly Lombardic, superstrate, Gallo-Italian descends from the Latin spoken in northern part of Italia (former Cisalpine Gaul). The group had for part of late antiquity and the early Middle Ages a close linguistic link with Gaul and Raetia, west and north to the Alps. From the late Middle Ages, the group adopted various characteristics of the Italo-Dalmatian languages of the south.
As a result, the Gallo-Italic languages have characteristics of the Gallo-Romance languages to the northwest (including French and Franco-Provençal), the Occitano-Romance languages to the west (including Catalan and Occitan) and the Italo-Dalmatian languages to the north-east, central and south Italy (Venetian, Dalmatian, Tuscan, Central Italian, Neapolitan, Sicilian). For this there is some debate over the proper grouping of the Gallo-Italic languages. They are sometimes grouped with Gallo-Romance, but other linguists group them in Italo-Dalmatian.
Most Gallo-Italic languages have to varying degrees given way in everyday use to regional varieties of Italian. The vast majority of current speakers are diglossic with Italian.
Among the regional languages of Italy, they are the most endangered, since in the main cities of their area (Milan, Turin, Genoa, Bologna) they are mainly used by the elderly.
Within this sub-family, the language with the largest geographic spread is Lombard, spoken in the Italian region of Lombardy, in eastern Piedmont and western Trentino. Outside Italy it is widespread in Switzerland in the canton of Ticino, and some southern valleys of the canton of the Grisons.
Piedmontese refers to the languages spoken in the region of Piedmont and the north west corner of Liguria. Historically, the Piedmontese-speaking area is the plain at the foot of the Western Alps, and ends at the entrance to the valleys where Occitan and Franco-Provençal are spoken. In recent centuries, the language has also spread into these valleys, where it is also more widely spoken than these two languages, thus the borders of Piedmontese have reached the western alps watershed that is the border with France.
The speaking area of Ligurian or Genoese cover the territory of the former Republic of Genoa, which included much of nowadays Liguria, and some mountain areas of bordering regions near the Ligurian border, the upper valley of Roya river near Nice, in Carloforte and Calasetta in Southern Sardinia, and Bonifacio in Corsica.
Emilian is spoken in the historical-cultural region of Emilia, which forms part of Emilia-Romagna, but also in many areas of the bordering regions, including southern Lombardy, south-eastern Piedmont, around the town of Tortona, province of Massa and Carrara in Tuscany and Polesine in Veneto, near the Po delta. With Romagnol, spoken in the historical region of Romagna, forms the Emilian-Romagnol linguistic continuum.
Gallo-Piceno (gallo-italic of the Marches or gallico-marchigiano) is spoken in the province of Pesaro and Urbino and in the northern part of the province of Ancona (the Marches). Once classified as a dialect of Romagnol, now there is a debate about considering it a separated Gallo-Italic language.
Varieties of Gallo-Italic languages are also found in Sicily, corresponding with the central-eastern parts of the island that received large numbers of immigrants from Northern Italy, called Lombards, during the decades following the Norman conquest of Sicily (around 1080 to 1120). Given the time that has lapsed and the influence from the Sicilian language itself, these dialects are best generically described as Southern Gallo-Italic. The major centres where these dialects can still be heard today include Piazza Armerina, Aidone, Sperlinga, San Fratello, Nicosia, and Novara di Sicilia. Northern Italian dialects did not survive in some towns in the province of Catania that developed large Lombard communities during this period, namely Randazzo, Paternò and Bronte. However, the Northern Italian influence in the local varieties of Sicilian are marked. In the case of San Fratello, some linguists suggested that the nowadays dialect has Provençal as its basis, having been a fort manned by Provençal mercenaries in the early decades of the Norman conquest (bearing in mind that it took the Normans 30 years to conquer the whole of the island).
Other dialects, attested from 13th and 14th century, are also found in Basilicata, more precisely in the province of Potenza (Tito, Picerno, Pignola and Vaglio Basilicata), Trecchina, Rivello, Nemoli and San Costantino.
Gallo-Italic languages are often said to resemble Western Romance languages like French, Spanish, or Portuguese, and in large part it is due to their phonology. The Gallo-Italic languages differ somewhat in their phonology from one language to another, but the following are the most important characteristics, as contrasted with Italian:
