Romanesco dialect
Romanesco () is one of the central Italian dialects spoken in the Metropolitan City of Rome Capital, especially in the core city. It is linguistically close to Tuscan and Standard Italian, with some notable differences from these two. Rich in vivid expressions and sayings, Romanesco is used in a typical diglossic setting, mainly for informal/colloquial communication, with code-switching and translanguaging with the standard language. History. The medieval Roman dialect belonged to the southern family of Italian dialects, and was thus much closer to the Neapolitan language than to the Florentine. A typical example of Romanesco of that  period is "Vita di Cola di Rienzo" ("Life of Cola di Rienzo"), written by an anonymous Roman during the 14th century. Starting with the 16th century, the Roman dialect underwent a stronger and stronger influence from the Tuscan dialect (from which modern Italian derives) starting with the reigns of the two Medici popes (Leo X and Clement VII) and with the Sack of Rome in 1527, two events which provoked a large immigration from Tuscany. Therefore, current Romanesco has grammar and roots that are rather different from other dialects in Central Italy. The path towards a progressive Tuscanization of the  dialect can be observed in the works of the major Romanesco writers and poets of the past two centuries: Giuseppe Gioachino Belli (1791–1863), whose "sonetti romaneschi" represent the most important work in this dialect and an eternal monument to 19th century Roman people; Cesare Pascarella (1858–1940); Giggi Zanazzo (1860–1911); and Carlo Alberto Salustri (1871–1950), nicknamed Trilussa. Diffusion. Before Rome became the capital city of Italy, Romanesco was spoken only inside the walls of the city, while the little towns surrounding Rome had their own dialects. Nowadays, these dialects have been replaced with a variant of Romanesco, which therefore is now  spoken in an area larger than the original one. It slightly pervades the everyday language of most of the immigrants who live in the large city. Pronunciation. Romanesco pronunciation and spelling differs from Standard Italian in these cases: Noteworthy figures. Today, Romanesco is generally considered more of a regional idiom than a true language. Classical Romanesco, which reached high literature with Giuseppe Gioachino Belli, has disappeared. External forces such as immigration and the dominance of Italian are playing a role in the transformation. <poem> "Ma nun c'è lingua come la romana" "Pe' dì una cosa co' ttanto divario  Che ppare un magazzino de dogana."      — G. G. Belli, "Le lingue der monno" But there is no language like the Roman one To express a concept with so many variants So that it seems a customs warehouse.      — G. G. Belli, "Languages of the world" </poem>
