The official language of Barbados is English. Bajan (sometimes called Barbadian Creole or Barbadian dialect) is a creole language based on Irish and English spoken by the locals. Bajan uses a mixture of West African idioms and expressions, such as Igbo, as well as British English and Irish to produce a vocabulary and mode of expression unique to Barbados and the Caribbean. A few African words are interspersed in the dialect. Communication will not be a problem for any English speaker, and Barbados has one of the highest literacy rates in the Western Hemisphere. Many Irish prisoners of war were sent to the island as indentured servants after the English Civil War. Some of their descendants are found in St John and St Phillip and are known as Poor Whites or Redlegs, another term that can be seen as racist.
