Saint Kitts Creole has much the same history as other English Caribbean creoles. Its origin lies in 17th-century enslaved West Africans, who, when brought to the islands to work on sugar plantations, were forced to learn British English quickly because their labour required it. Their English was mixed with West African words and, in some cases, West African language structure. The French, who occupied the island from 1625 to 1713, had only a small impact on the creole spoken today, unlike in the formerly French islands of Dominica and Saint Lucia, which speak a French-based rather than English-based creole.
