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.
Proto-Romanian language
The Roman occupation led to a Roman-Thracian syncretism, and similar to the case of other conquered civilisation (see Gallo-Roman culture developed in Roman Gaul), had as final result the Latinization of many Thracian tribes which were on the edge of the sphere of Latin influence, eventually resulting in the possible extinction of the Daco-Thracian language (unless, of course, Albanian is its descendant), but traces of it are still preserved in the Eastern Romance substratum. From the 2nd century AD, the Latin spoken in the Danubian provinces starts to display its own distinctive features, separate from the rest of the Romance languages, including those of western Balkans (Dalmatian). The Thraco-Roman period of the Romanian language is usually delimited between the 2nd century (or earlier via cultural influence and economic ties) and the 6th or the 7th century. It is divided, in turn, into two periods, with the division falling roughly in the 3rd to 4th century. The Romanian Academy considers the 5th century as the latest time that the differences between Balkan Latin and western Latin could have appeared, and that between the 5th and 8th centuries, the new language, Romanian, switched from Latin speech, to a vernacular Romance idiom, called Română comună.
