Chad
The African nation of Chad is home to Lake Chad, it means "lake". So it's more like "lake lake". Kinda like how the Sahara Desert means "desert desert". Chad's Washington, D.C. embassy is a mere 200 feet away from that of Burkina Faso. Chad's capital city is N'Djamena, on the banks of the Chari River right along the Cameroonian border.
