Romani people
Most Romani speak one of several dialects of the Romani language, an Indo-Aryan language, with roots in Sanskrit. They also often speak the languages of the countries they live in. Typically, they also incorporate loanwords and calques into Romani from the languages of those countries and especially words for terms that the Romani language does not have. Most of the "Ciganos" of Portugal, the Gitanos of Spain, the Romanichal of the UK, and Scandinavian Travellers have lost their knowledge of pure Romani, and respectively speak the mixed languages Caló, Angloromany, and Scandoromani. Most of the speaker communities in these regions consist of later immigrants from eastern or central Europe.
Romano-Greek language
Romano-Greek (also referred to as Hellenoromani; ) is a nearly extinct mixed language (referred to as Para-Romani in Romani linguistics), spoken by the Romani people in Greece that arose from language contact between Romani speaking people and the Greek language. The language is expected to be a secret language spoken in Thessaly and Central Greece Administrative Unit. Typologically the language is structured on Greek with heavy lexical borrowing from Romani. Related variants of this language are Dortika. Dortika is a secret language spoken mainly in Athens by traveling builders from Eurytania Prefecture. In both cases, the languages are most likely not native to their speakers.
