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.

In a series of articles (beginning from 1982), Marcel Courthiade proposed a different kind of classification. He concentrates on the dialectal diversity of Romani in three successive strata of expansion, using the criteria of phonological and grammatical changes. Finding the common linguistic features of the dialects, he presents the historical evolution from the first stratum (the dialects closest to the Anatolian Romani of the 13th century) to the second and third strata. He also names as "pogadialects" (after the "" dialect of Great Britain) those with only a Romani vocabulary grafted into a non-Romani language (normally referred to as Para-Romani).
