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.
Sardinian language
Sardinian or Sard ("sardu" , "limba sarda" or "língua sarda" ) is the primary indigenous Romance language spoken by the Sardinians on most of the island of Sardinia. It is considered one of the closest genealogical descendants, if not the closest, to Latin by many Romance linguists. However, it also incorporates a Pre-Latin (mostly Paleo-Sardinian and, to a much lesser degree, Punic) substratum, as well as a Byzantine Greek, Catalan, Spanish and Italian superstratum due to the political membership of the island, which became a Byzantine possession followed by a significant period of self-rule, fell into the Iberian sphere of influence in the late Middle Ages, and eventually into the Italian one in the 18th century.
