1550s, from Sp. canibal "a savage, cannibal," from Caniba, Christopher Columbus' rendition of the Caribs' name for themselves (see Caribbean). The natives were believed to be anthropophagites. Columbus, seeking evidence that he was in Asia, thought the name meant the natives were subjects of the Great Khan. Shakespeare's Caliban (in "The Tempest") is a version of this word, with -n- and -l- interchanged, found in Hakluyt's "Voyages" (1599). The Sp. word had reached French by 1515.
