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.
Classification of Romance languages
Romanian, together with other related languages, like Aromanian, has a number of grammatical features which are unique within Romance, but are shared with other non-Romance languages of the Balkans, such as Albanian, Bulgarian, Greek, Macedonian, Serbo-Croatian and Turkish. These include, for example, the structure of the vestigial case system, the placement of articles as suffixes of the nouns (' = "sky", ' = "the sky"), and several more. This phenomenon, called the Balkan language area, may be due to contacts between those languages in post-Roman times.
