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.
Romani language
However, Matras describes it further. According to Matras, in most dialects of Romani, Romani is a VO language, with SVO order in contrastive sentences and verb-subject-object order in thetic sentences. The tendency to put verb on the end in some dialects is the Slavic influence.
