First attested in the 18th century. From a Bantu language. Compare Kongo nzambi (“god”), zumbi (“fetish”), and Kimbundu nzumbi (“ghost”) (see Portuguese zumbi, Sranan Tongo dyumbi), and Caribbean folklore's jumbee (“a spirit or demon”). May have come through Louisiana Creole zombi (“zombie; ghost”). See also French zombi (“zombie”). A possible origin from Spanish sombra (“shadow, phantom”) has also been suggested.
Often used metaphorically to describe a person who is extremely tired or lacks independent thought.
