French 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 evolved from Gallo-Romance, the spoken Latin in Gaul, and more specifically in Northern Gaul.

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 the fourth most widely spoken mother tongue in the European Union. Of Europeans who speak other languages natively, approximately one-fifth are able to speak French as a second language.

French is estimated to have about 76 million native speakers and about 235 million daily, fluent speakers and another 77 to 110 million secondary speakers who speak it as a second language to varying degrees of proficiency.

French has a long history as an international language is a primary or second language of many international organisations including the United Nations, the European Union, the World Trade Organization, the International Olympic Committee, and the International Committee of the Red Cross.

In 2011, Bloomberg Businessweek ranked French the third most useful language for business, after English and Standard Mandarin Chinese.
