I am unaware of the language or dialect from which the word BAKU was taken and became inclusive in creol which permeates the lives and tongues of Guyanese. I am, however, surprised to see that "BAKU" which was referred to as "mythology" in your article, is an accepted "Western Norm" referred to as a "POLTERGEIST" which is a term of German origin for the same entity.

But in Guyana its not really referred to as a "spirit" or jumbee which is a ghost. The countyside version is Supposedly they are little men that certain people keep and feed them bananas. they are mischievous and pelt and beat people in dark area and shrubs
From what I see they sound more like leprechauns, without the hat, the gold and the rainbow. they are bad

A spirit of small stature that pelts stones at houses and moves objects within a house. He is supposed to live on banana and milk. Stories abound of the existence of bacoos in Georgetown and other areas in Guyana. Could have come from Surinam and are said to be trapped in a corked bottle unless released. Active mainly at night, it is said that a satisfied bacoo will answer the wishes of its owner
