What is mumbo jumbo? How to use in English

The word "mumbo jumbo" originated in the late 19th century and has its roots in the African slave trade. Its exact origins are disputed, as various theories have been put forth over time. One popular theory suggests that the word comes from the Bantu language, spoken in parts of Africa where many slaves were taken from. In particular, it is thought to be a corruption of the Kongo word "anti-mbumbu," meaning "oracle bone" or "magic bone." Some slaves may have used this term to refer to the mysterious objects and practices associated with religious ceremonies. Alternatively, it is possible that the term evolved locally among enslaved African communities in the United States. Some versions of this theory suggest that "mumbo jumbo" originated in the Gullah language, a creole dialect spoken by enslaved people in the Lowcountry of South Carolina and Georgia. Still others suggest that it came from the Akan language, spoken in Ghana and the Ivory Coast, and its literal translation into English is "wealth, riches." Regardless of its origins, by the late 1800s, "mumbo jumbo" was being used in popular culture as a term to describe both religious and medical quackery, as well as any kind of nonsense or false pretense. Today, it remains a part of the English language, often used to describe confusing or difficult-to-understand concepts or practices.
