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.
Gitanos
More exactly, Romani shares the basic lexicon with Hindi and Punjabi. It shares many phonetic features with Marwari, while its grammar is closest to Bengali. Linguistic evaluation carried out in the nineteenth century by Pott (1845) and Miklosich (1882–1888) showed that the Romani language is to be classed as a New Indo-Aryan language (NIA), not a Middle Indo-Aryan (MIA), establishing that the ancestors of the Romani could not have left the Indian subcontinent significantly earlier than AD 1000, then finally reaching Europe several hundred years later.
