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.
History of Romanian
Francesco della Valle writes in 1532 that "they name themselves Romei in their own language" ("si dimandano in lingua loro Romei") and, he also cites the expression "Do you know Romanian?" ("se alcuno dimanda se sano parlare in la lingua valacca, dicono a questo in questo modo: Sti Rominest ? Che vol dire: Sai tu Romano?").
