While French is an official language in many West African countries, all ECOWAS members are officially Anglophone or have English as one of their official languages.
Here's why there's confusion:
* French-speaking West African countries: Many countries in West Africa are predominantly French-speaking, like Senegal, Mali, Côte d'Ivoire, Burkina Faso, Niger, Benin, and Togo.
* ECOWAS membership: These countries are part of the West African Economic and Monetary Union (WAEMU), a separate economic community.
Therefore, while these French-speaking West African nations are geographically close and have strong historical and cultural ties, they are not members of ECOWAS.
