Hancock says that Guinea Coast Creole English ultimately gave rise to the pidgin and creole languages spoken in West Africa today, such as the Aku language in the Gambia, Sierra Leone Krio, Nigerian Pidgin English and Cameroonian Pidgin English. He also maintains that some of the Africans taken as slaves to the New World already spoke Guinea Coast Creole English in Africa. Their creole speech influenced the development of creole languages spoken today on the American side of the Atlantic, such as Gullah, Afro-Seminole Creole, Bahamian Dialect, Jamaican Creole, Belizean Kriol, Guyanese Creole, and Sranan Tongo in Suriname.
