It's important to note that this list does not include all countries where French is spoken. Many other countries have French as an official language, a second language, or a widely spoken language.
Additionally, there are many regions within countries where French is spoken as a maternal language, even though it is not the official language of the entire country. For example, French is widely spoken in certain regions of Belgium, Switzerland, and Canada, even though it is not the official language of those entire countries.
