Senegambian languages

The Senegambian languages, also called Northern West Atlantic, are a branch of the Atlantic-Congo languages spoken chiefly in Senegal and neighboring southern Mauritania, the Gambia, Guinea-Bissau, and Guinea. The nomadic Fula people carried their languages from Senegal across the western and central Sahel. Wolof, the national language of Senegal, has around four million native speakers and millions more second-language users, Fula varieties have roughly 13 million speakers combined, and Serer has more than a million. Unlike most Atlantic-Congo languages, the Senegambian languages are notably devoid of tone.
