the word 'zombie' entered english in the early 19th century, originating from west african languages. it is likely derived from 'nzambi', a term for a god or spirit in the kongo language, and 'zumbi', meaning 'fetish' or 'idol'. the term was transmitted to the caribbean and the americas via the transatlantic slave trade, where it became central to haitian vodou beliefs concerning a reanimated corpse. english adopted the word, initially in accounts of haitian folklore, and it later became a staple of global popular culture, particularly in horror fiction and film, broadening in meaning to describe a mindless, automated person.

the word is a loanword adopted as a single, unanalyzable unit in english. its constituent parts in the source language are not direct substrings of the modern english spelling.
