Guyana officially the Co-operative Republic of Guyana and previously known as British Guiana, is the only country of the Commonwealth of Nations on the mainland of South America. It is bordered to the east by Suriname, to the south and southwest by Brazil and to the west by Venezuela. It is the fourth-smallest country on the mainland of South America (after Suriname, French Guiana, and Uruguay). It is one of the four non-Spanish-speaking territories on the continent, along with the countries of Brazil (Portuguese), Suriname (Dutch) and the French overseas region of French Guiana (French). Culturally, Guyana associates primarily with the English-speaking Caribbean countries such as Jamaica, or Trinidad and Tobago.
