Gypsy Wedding

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).
• English usage
In the English language (according to the Oxford English Dictionary), Rom is a noun (with the plural Roma or Roms) and an adjective, while Romani (Romany) is also a noun (with the plural Romanies or Romanis) and an adjective. Both Rom and Romani have been in use in English since the 19th century as an alternative for Gypsy. Romani was initially spelled Rommany, then Romany, while today the Romani spelling is the most popular spelling. Occasionally, the double r spelling (e.g., Rroma, Rromani) mentioned above is also encountered in English texts.
