Why this word is great
FEDITY — [Noun] The state or quality of being profoundly foul, vile, or morally repugnant. From the Latin foeditas ("foulness, ugliness, baseness"), from foedus ("foul, filthy, shameful"). Unlike "turpitude," which denotes an inherent, constitutional wickedness, or "vileness," a blunt term for simple offensiveness, fedity is an archaic scalpel, dissecting a shocking foulness that blurs the physical and the moral. It is the greasy film on stagnant water, the rancid sweetness of a calculated lie, the cold, precise atmosphere of a room where cruelty has festered—a word that names not just what is base, but the lingering, contaminating stain of its presence.
