French (français [fʁɑ̃sɛ] or langue française [lɑ̃ɡ fʁɑ̃sɛːz] ) is a Romance language of the Indo-European family. Like all other Romance languages, it descended from the Vulgar Latin of the Roman Empire. French evolved from Northern Old Gallo-Romance, a descendant of the Latin spoken in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. It was also influenced by native Celtic languages of Northern Roman Gaul and by the Germanic Frankish language of the post-Roman Frankish invaders. As a result of French and Belgian colonialism from the 16th century onward, it was introduced to new territories in the Americas, Africa, and Asia, and numerous French-based creole languages, most notably Haitian Creole, were developed. A French-speaking person or nation may be referred to as Francophone in both English and French.
French is an official language in 26 countries, as well as one of the most geographically widespread languages in the world, with speakers in about 50 countries. Most of these countries are members of the Organisation internationale de la Francophonie (OIF), the community of 54 member states which share the use or teaching of French. It is estimated to have about 310 million speakers, of which about 74 million are native speakers; it is spoken as a first language (in descending order of the number of speakers) in France, Canada (Quebec), Belgium (Wallonia and the Brussels-Capital Region), western Switzerland (Romandy region), parts of Luxembourg, and Monaco. Meanwhile in Francophone Africa it is spoken mainly as a second language or lingua franca, though it has also become a native language in a small number of urban areas; in some North African countries like Algeria, despite not having official status, it is also a first language among some upper classes of the population alongside the indigenous ones, but only a second one among the general population.
