Etymology: Coined in the 1950s, "menticide" is a deliberate blend rather than an old word that drifted into use. Its first half comes from Latin "mens" ("mind"), or possibly from "mentalis" ("mental"), while the second half, "-cide" ("killing"), comes from Latin "-cidium." The ending was borrowed by analogy with words such as "homicide" and "genocide," so the coinage reads as "mind-killing." The term was built to name a particular kind of psychological harm: a methodical campaign to break down a person's existing beliefs and replace them with imposed ones. The "-cide" ending is metaphorical here, since the target is a mind rather than a body, which is why the coinage borrows the vocabulary of mass violence to describe an intellectual process.
