Gypsies, known more politically correctly as the Romani, Romany or Roma, are members of an ethnic group thought to have originated from the Indian subcontinent, and who now live throughout Europe, the Middle East, Australia and the Americas.
Angloromani, for example, is the main language of England's Romani community. It is thought to be spoken by around 90,000 people in the UK and 200,000 globally (with other communities in Australia, the USA and South Africa). But it is not recognised as a native language by the government. Vlax Romani, another branch of the Romani family, is as native to the UK as it is to much of Europe.
