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.
Sardinian language
Sardinian or Sard ("sardu" , "limba sarda" or "língua sarda" ) is the primary indigenous Romance language spoken by the Sardinians on most of the island of Sardinia. It is considered one of the closest genealogical descendants, if not the closest, to Latin by many Romance linguists. However, it also incorporates a Pre-Latin (mostly Paleo-Sardinian and, to a much lesser degree, Punic) substratum, as well as a Byzantine Greek, Catalan, Spanish and Italian superstratum due to the political membership of the island, which became a Byzantine possession followed by a significant period of self-rule, fell into the Iberian sphere of influence in the late Middle Ages, and eventually into the Italian one in the 18th century.
