The Romani are widely dispersed, with their largest concentrated populations in Europe, especially the Roma of Central and Eastern Europe and Anatolia, followed by the Iberian Kale in Southwestern Europe and Southern France. Deported to Brazil by Portugal during the colonial era and via more recent migrations, some people have gone to the Americas and, to a lesser extent, other parts of the world.
The Romani language is divided into several dialects, which add up to an estimated number of speakers larger than two million. The total number of Romani people is at least twice as large (several times as large according to high estimates). Many Romani are native speakers of the language current in their country of residence, or of mixed languages combining the two.
In the Romani language, rom is a masculine noun, meaning "man, husband", with the plural roma. Romani is the feminine adjective, while romano is the masculine adjective. Some Romanies use Rom or Roma as an ethnic name, while others (such as the Sinti, or the Romanichal) do not use this term as a self-ascription for the entire ethnic group.
Sometimes, rom and romani are spelled with a double r, i.e., rrom and rromani. In this case rr is used to represent the phoneme /ʀ/ (also written as ř and rh), which in some Romani dialects has remained different from the one written with a single r. The rr spelling is common particularly in Romania, in order to distinguish from the endonym for Romanians (sg. român, pl. români).
