Senegal (l/ (listen); French: Sénégal), officially the Republic of Senegal (French: République du Sénégal), is a country in West Africa. Senegal is bordered by Mauritania in the north, Mali to the east, Guinea to the southeast, and Guinea-Bissau to the southwest. Senegal also borders The Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. Senegal also shares a maritime border with Cape Verde. Senegal's economic and political capital is Dakar.
Probably from a Portuguese transliteration of the name of the Zenaga also known as the Sanhaja, or a combination of the supreme deity in Serer religion (Rog Sene) and o gal meaning body of water in the Serer language. Alternatively, the name could derive from the Wolof phrase "Sunuu Gaal," which means "our boat."
