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.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.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.
