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.
Romano-Greek language
Romano-Greek (also referred to as Hellenoromani; ) is a nearly extinct mixed language (referred to as Para-Romani in Romani linguistics), spoken by the Romani people in Greece that arose from language contact between Romani speaking people and the Greek language. The language is expected to be a secret language spoken in Thessaly and Central Greece Administrative Unit. Typologically the language is structured on Greek with heavy lexical borrowing from Romani. Related variants of this language are Dortika. Dortika is a secret language spoken mainly in Athens by traveling builders from Eurytania Prefecture. In both cases, the languages are most likely not native to their speakers.
