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 the Romani people
Domari was once thought to be the "sister language" of Romani, the two languages having split after the departure from the South Asia, but more recent research suggests that the differences between them are significant enough to treat them as two separate languages within the Central zone (Hindustani) Saraiki language group of languages. The Dom and the Rom are therefore likely to be descendants of two different migration waves from the Indian subcontinent, separated by several centuries.
