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.
Angloromani language
Anglo-Romani was already developing in the seventeenth century although the change from the original English Romani is unclear. The "Winchester confessions" document disproves a sudden morphological change, and lends support to a strict linguistic separation between a Canting language and English Romani whose speakers used a separate and distinct Romani language when speaking amongst themselves. A situation which existed one hundred years later as testified by James Poulter 1775: "the English Gypsies spoke a variant of their own language that none other could understand," indicating the language was distinct from the common "Canting tongue" of England. Romani of that time was a language of everyday communication, of practical use, and not a secret language.
