Portuguese (endonym: português or língua portuguesa) is a Western Romance language of the Indo-European language family originating from the Iberian Peninsula of Europe. It is spoken chiefly in Brazil, Portugal, and several countries in Africa, as well as by immigrants in North America, Europe, and South America. With approximately 267 million speakers, it is listed as the fifth-most spoken native language.
Portuguese-speaking people or nations are known as Lusophone (lusófono). As a result of expansion during colonial times, a cultural presence of Portuguese speakers is also found around the world. Portuguese is part of the Ibero-Romance group, which evolved from several dialects of Vulgar Latin in the medieval Kingdom of Galicia and the County of Portugal, and has retained some Celtic phonology.
