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.
Romanian language
Pierre Lescalopier writes in 1574 that those who live in Moldavia, Wallachia and the vast part of Transylvania, ""se consideră adevărați urmași ai romanilor și-și numesc limba "românește", adică romana"" ("they consider themselves as the descendants of the Romans and they name their language Romanian").
