尼加拉瓜湖
Nicaragua's name is derived from Nicarao, the name of the Nahuatl-speaking tribe which inhabited the shores of Lake Nicaragua before the Spanish conquest of the Americas, and the Spanish word "agua", meaning water, due to the presence of the large Lake Cocibolca (or Lake Nicaragua) and Lake Managua (or Lake Xolotlán), as well as lagoons and rivers in the region.
