French (le français[lə fʁɑ̃sɛ] ( listen) or la langue française[la lɑ̃ɡ fʁɑ̃sɛz]) is a Romance language spoken as a first language in France, the Romandy region in Switzerland, Wallonia and Brussels in Belgium, Monaco, the provinces of Quebec and New Brunswick (Acadia region) in Canada, the U.S. state of Maine, the Acadiana region of the U.S. state of Louisiana, and by various communities elsewhere. Other speakers of French, who often speak it as a second language, are distributed throughout many parts of the world, the largest numbers of whom reside in Francophone Africa. In Africa, French is most commonly spoken in Gabon (where 80% report fluency), Mauritius (78%), Algeria (75%), Senegal and Côte d'Ivoire (70%). French is estimated as having 110 million native speakers and 190 million more second language speakers.
French is a descendant of the spoken Latin language of the Roman Empire, as are languages such as Italian, Portuguese, Spanish, Romanian, Lombard, Catalan, Sicilian and Sardinian. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in Belgium, which French has largely supplanted. French was also influenced by native Celtic languages of Roman Gaul 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.
