French

French is an official language in 29 countries and spoken across five continents. It's the working language of the UN, NATO, the EU, the International Olympic Committee, and the Red Cross. Africa is the fastest-growing Francophone region — by 2050, an estimated 700 million people will speak French, mostly in sub-Saharan Africa's rapidly growing economies. France itself is the world's seventh-largest economy. In luxury goods, fashion, hospitality, diplomacy, and international development, French remains non-negotiable.
