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.
Para-Romani
Para-Romani are various mixed languages of non-Indo-Aryan linguistic classification containing considerable admixture from the Romani language. They are spoken as the traditional vernacular of Romani communities, either in place of, or alongside, varieties of the Romani language. Some Para-Romani languages have no structural features of Romani at all, taking only the vocabulary from Romani.
