cannibalism

The word's journey begins with the Spanish caníbal, a variant of Caribal (Carib), the name of an indigenous people of the West Indies encountered by Christopher Columbus. European explorers, influenced by reports and perhaps misunderstandings, attributed the practice of ritual anthropophagy to the Caribs, leading their ethnonym to become synonymous with man-eaters. The suffix -ism, of Greek origin via Latin, was later appended to form an abstract noun denoting the practice or doctrine itself. Thus, the term evolved from a specific ethnic name, through a process of semantic shift and generalization, to its modern meaning of intraspecies consumption, later extended metaphorically to describe self-destructive behavior within a group.
