A country on the northern coast of South America. It was formerly a British colony known as British Guiana. In 1966, after more than 150 years of colonial rule, British Guiana achieved independence and took the name Guyana, from a Native American word meaning “land of waters.” The country’s full name is Cooperative Republic of Guyana. Today, Guyana is a member of the Commonwealth of Nations, an association of nations that once formed the British Empire. It is the only English-speaking country in South America. Although Guyana is a South American nation, it has more in common with the smaller islands of the West Indies, with which it shares certain cultural, historical, and economic characteristics.
