It is an English-based creole with a strong Akan component, specifically from the Asante dialect of modern day Ghana.
Another distinct ritual language (also called Kromanti) consisting mostly of words and phrases from Akan languages, is also used by Jamaican Maroons in certain rituals including some involving possession by ancestral spirits during Kromanti ceremonies or when addressing those who are possessed and sometimes used as a kind of code.
[1][2] The term "Kromanti" is used by participants in such ceremonies to refer to an African language spoken by ancestors in the distant past, prior to the creolization of Jamaican Maroon Creole.
This term is used to refer to a language which is "clearly not a form of Jamaican Creole and displays very little English content" (Bilby 1983: 38).
[3] While Kromanti is not a functioning language, those possessed by ancestral spirits are attributed the ability to speak it.
