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.
Romanian language
The Croatian prelate and diplomat Antun Vrančić recorded in 1570 that ""Vlachs in Transylvania, Moldavia and Wallachia designate themselves as "Romans"" and the Transylvanian Hungarian Martin Szentiványi in 1699 quotes the following: "«Si noi sentem Rumeni»" ("Și noi suntem români" – "We are Romans as well") and "«Noi sentem di sange Rumena»" ("Noi suntem de sânge român" – "We are of Roman blood"). Notably, Szentiványi used Italian-based spellings to try to write the Romanian words.
