Western Europe:
* France (the origin of the language)
* Belgium (alongside Dutch and German)
* Luxembourg (alongside German and English)
* Monaco
* Switzerland (alongside German, Italian and Romansh)
Other:
* Andorra (alongside Catalan)
It's important to note that in some of these countries, French is spoken by a smaller percentage of the population than other languages. For example, in Belgium, only about 40% of the population speaks French as their native language.
Additionally, French is spoken by significant minorities in other European countries, such as:
* Italy (especially in the Aosta Valley region)
* Spain (especially in the Basque Country and Catalonia)
* Germany (especially in the Alsace-Lorraine region)
* United Kingdom (especially in the Channel Islands)
So while French is officially recognized in only a few European countries, its influence and use extends far beyond those borders.
