Romani language
Romani (; also Romany; ) is any of several languages of the Romani people belonging to the Indo-Aryan branch of the Indo-European language family. According to Ethnologue, seven varieties of Romani are divergent enough to be considered languages of their own. The largest of these are Vlax Romani (about 500,000 speakers), Balkan Romani (600,000), and Sinte Romani (300,000). Some Romani communities speak mixed languages based on the surrounding language with retained Romani-derived vocabulary – these are known by linguists as Para-Romani varieties, rather than dialects of the Romani language itself.
Eastern Romance languages
According to the generally accepted theory regarding their origin, the Eastern Romance languages, are considered to be a evolution of the Vulgar-Latin, spoken in the Balkan area during the domination of the Roman Empire. The Vulgar-Latin, in its turn, is considered to be a mixture of the ancient, local languages: Illyrian, Thracian, Dacian, and the official Latin (the language of Rome). It formed for centuries a language continuum, spread across the Balkans.
After the arrival of Slavic people in the region ( V-VII cent.), many of the indigenous people were assimilated while others were obliged to move and disperse, losing in that way the homogeneity and the previous contacts between them. As a result, the formation of the four languages, that nowadays constitute the Eastern branch of the Romance Languages family, took place.
