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.
Rome
Although associated today only with Latin, ancient Rome was in fact multilingual. In highest antiquity, Sabine tribes shared the area of what is today Rome with Latin tribes. The Sabine language was one of the Italic group of ancient Italian languages, along with Etruscan, which would have been the main language of the last three kings who ruled the city till the founding of the Republic in 509 BC. Urganilla, or Plautia Urgulanilla, wife of Emperor Claudius, is thought to have been a speaker of Etruscan many centuries after this date, according to Suetonius' entry on Claudius. However Latin, in various evolving forms, was the main language of classical Rome, but as the city had immigrants, slaves, residents, ambassadors from many parts of the world it was also multilingual. Many educated Romans also spoke Greek, and there was a large Greek, Syriac and Jewish population in parts of Rome from well before the Empire.
