Peripeteia (PAIR uh puh tay uh) is a noun that refers to a sudden reversal of fortune.
Our word of the day comes directly from the Greeks. It’s derived from the words that mean ‘around’ and ‘fall.’ The Greeks used it often in tragedy, which would feature a mighty figure seeing his or her fortune disappear, but the word may be used in more lightweight circumstances too:
After find a winning night at poker, Bradley found a peripeteia the next day. He woke up and discovered he’d been robbed.
