Why “postmonition” is a great word
POSTMONITION — [Noun] An intimation or sense of a past disaster, typically experienced after the event has occurred. Formed by analogy with premonition, from the Latin prefix post- ("after") and monitio ("warning"). Unlike "premonition," which haunts the present with the future's shadow, or "hindsight," which is the cold clarity of logic, a postmonition is a belated, spectral echo of a concluded catastrophe. It is the inexplicable chill upon entering a room where an argument has just ended, the sudden shudder while passing a stretch of road where an accident you never witnessed occurred, or the vivid, unplaceable dream of a train wreck that the morning paper confirms happened yesterday—a haunting proof that the soul’s clock can keep a different, slower time.
