Mumbo jumbo is a term that dates back to the mid-eighteenth century. We will examine the definition of mumbo jumbo, where it came from and some examples of its use in sentences.
Mumbo jumbo is speech, writings or ideas that are nonsensical. Mumbo jumbo may be gibberish, overly complicated language or superstitious religious ritual. The word mumbo jumbo entered the English language in the 1730s as a corruption of the name of a Mandingo religious figure, Maamajomboo. This figure was a male dancer employed to instill obedience in the women of the tribe, according to European observers. For the most part, mumbo jumbo is considered a benign term and is frequently used as a business buzzword. However, but one must be careful in what context it is used, and if in doubt, choose another word. According to the Oxford English Dictionary, mumbo jumbo is properly rendered without a hyphen.
