Why “hereticide” is a great word

HERETICIDE — [Noun] The deliberate killing of a person deemed a heretic. Forged from *heretic*, one who dissents from orthodox doctrine, and the terminal *-cide*, from Latin *caedere*, to cut down or kill. Unlike "heresy" (which names the dissenting belief itself) or "martyrdom" (which sanctifies the victim’s faithful witness), hereticide fixes its cold gaze on the perpetrator's rationale: the purgation of doctrinal impurity. It is the solemn verdict of the inquisitorial court, the specific heft of the stone cast by the righteous crowd, the methodical stacking of faggots around a stake—the violent grammar by which a faith seeks to punctuate its own unity.

noun

The killing of a heretic.
