Why this word is great
OSSARIUM — [Noun] A container, vault, or building where the bones of the dead are deposited. From Latin ossārium, from os, ossis (“bone”) and the suffix -ārium (“place for”). Unlike “ossuary,” its generalized descendant, or “charnel house,” with its architectural and macabre resonance, “ossarium” carries the chill of classical precision, a term for the bone-place as a studied category. It is the neat, labeled niche in a catacomb, the plain stone casket holding a dynasty's remains, and the terracotta pot into which the cleaned skeleton is folded—a final, silent arithmetic of a life, subtracted to its essential minerals.
