Jewish languages such as Yiddish, Ladino and various dialects of Judeo-Arabic to Modern Hebrew. Italy The Italian peninsula, the Po river basin and the nearby islands are home to various languages, most of which are Latin-derived. Italy would be politically organized into states until the late 19th century. Since the times of the Renaissance, a trans-Italian language was developed in central Italy, based on Florentine Tuscan; in light of its cultural prestige, it was used for formal, literary and written purposes among the literate classes from the various states of mainland Italy, Sicily and Corsica (France), sidelining the other dialects in education and formal settings. Thus, literary Florentine was established as the most representative dialect of Italy long before its political unification in 1861, Tuscan having been officially adopted by the preunitarian states. Italian further expanded as a common language for everyday use throughout the country after World War II. Most other languages, with the exception of those spoken by specific ethno-linguistic groups, long served as local vernaculars alongside Italian; therefore they have been mislabelled "dialects" by their own speakers, but they are still usually spoken just as much as standard Italian in a diglossic spectrum with little conflict. For instance, the local Venetian dialects in Northeast Italy are widely used and locally promoted in the region; after all, Italian had been an integral part of the Republic of Venice since the 14th century, whose elites used to revere the most prominent Tuscan authors and tuscanize their own speech as well. On a survey made by Il Gazzettino in 2015, 70% of respondents told they spoke Venetian "very or quite often" in the family, while 68% with friends. A much lower percentage reported to use it at work (35%); the local language is less used in formal situations. However, the frequency of use within the family networks and friendship stopped respectively at -4 and -11 percentage points, suggesting a slow morphing to Italian, while the use in the workplace dropped to -22 percentage points. A visible generational gap has also been noted, since the students and young people under the age of 25 are the social group where the use of dialect fell below the threshold of absolute majority (respectively 43 and 41%). Nonetheless, despite some tendencies signalling the slow advancement of standard Italian, the local dialects of Veneto and the Province of Trieste are still widely spoken alongside Italian;
