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.
Romance languages
This was the pattern followed by the Romance languages: In the Romance languages that still preserved a functioning nominal case system (e.g., Romanian and Old French), only the combination of article and case ending serves to uniquely identify number and case (compare the similar situation in modern German). All Romance languages have a definite article (originally developed from "ipse" "self" but replaced in nearly all languages by "ille" "that (over there)") and an indefinite article (developed from "ūnus" "one"). Many also have a partitive article ("dē" "of" + definite article).
