The Romani people (/ˈroʊməni/ or /ˈrɒməni/), also known as the Roma (sg.: Rom) or Romanies (sg.: Romany), are an Indo-Aryan ethnic group who traditionally lived a nomadic lifestyle. Although they are widely dispersed, their most concentrated populations are believed to be in Romania, Bulgaria, Hungary, Serbia, and Slovakia. In the English language, Romani people have long been known by the exonym Gypsies or Gipsies and this remains the most common English term for the group. Some Roma use and embrace this term while others consider it to be derogatory or an ethnic slur.
Romani culture has been influenced by their time spent under various reigns and empires, notably the Byzantine and Ottoman empires. The Romani language is an Indo-Aryan language with strong Persian, Armenian, Byzantine Greek and South Slavic influence. It is divided into several dialects, which together are estimated to have over 2 million speakers. Many Roma are native speakers of the dominant language in their country of residence, or else of mixed languages that combine the dominant language with a dialect of Romani in varieties sometimes called para-Romani.
