Romagnol (Rumagnòl, or Rumagnôl; romagnolo) is a Romance language spoken in the historical region of Romagna, consisting mainly of the southeastern part of Emilia-Romagna, Italy. The name is derived from the Lombard name for the region, Romagna. Romagnol is also spoken outside the region, particularly in the independent Republic of San Marino. Romagnol is classified as endangered because older generations have "neglected to pass on the dialect as a native tongue to the next generation". Romagnol belongs to the Gallo-Italic family alongside Piedmontese, Ligurian and Lombard, forming with Emilian and as one of the two branches of the Emilian-Romagnol linguistic continuum. Further groupings of variants of Romagnol has not been set yet and both speakers and authors tend to refer to their own town or the nearest major province cities. The variants of Romagnol form a dialect continuum with their neighbouring varieties, while the more distant dialects might be less mutually intelligible. Variants spoken north of the Santerno river are considered by speakers of Sammarinese as being less, but still, intelligible, while passed the Sillaro such intellegibility is lost. In the West, The Sillaro river marks the cultural and linguistic border between Emilian language speakers and Romagnol speakers; it runs 25 km east from Bologna to the west of Castel San Pietro Terme. Romagnol is spoken to the east of this river and to the south of the Reno river. In the rest of Emilia-Romagna Region, Emilian is spoken in all the rest of the region moving from the Sillaro river to the west, up to Piacenza, and to the north of the Reno, up to the Po. The Reno River is the border between Romagnol and the dialect of Ferrara. Romagnol is spoken also in some villages northwards of the Reno River, such as Argenta and Filo, where people of Romagnol origin live alongside people of Ferrarese origin. Ferrara goes into Emilian language territory. Outside Emilia-Romagna, Romagnol is spoken in the Republic of San Marino ("Sammarinese"), and in two municipalities located in the province of Florence, Marradi and Palazzuolo sul Senio.
