French (le français [lə fʁɑ̃sɛ] ( listen) or la langue française [la lɑ̃ɡ fʁɑ̃sɛz]) is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French has evolved from Gallo-Romance, the spoken Latin in Gaul, and more specifically 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) has largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to France 's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French.
French is an official language in 29 countries across five different continents, most of which are members of the Organisation internationale de la Francophonie (OIF), the community of 84 countries which share the official use or teaching of French. It is spoken as a first language (in descending order of the number of speakers) in France, Canadian provinces of Quebec, Ontario and New Brunswick as well as other Francophone regions, Belgium (Wallonia and Brussels), western Switzerland (cantons of Bern, Fribourg, Geneva, Jura, Neuchâtel, Vaud, Valais), Monaco, parts of the United States (Louisiana, Maine, New Hampshire, and Vermont), and by various communities elsewhere. In 2015, approximately 40% of the francophone population (including L2 and partial speakers) lived in Europe, 35% in sub-Saharan Africa, 15% in North Africa and the Middle East, 8% in the Americas, and 1% in Asia and Oceania.
