Pronounced: MY-kroh-burst, noun
Notes: This word is much more specific than I thought it was.
The word eucatastrophe means, as you may have guessed, “a happy ending” – especially one in which, instead of an impending disaster, a sudden turn leads to a favorable resolution of the story.
I figured that most readers would recognize that this is just the word catastrophe with eu- (good) prepended. It’s all from Greek roots; in addition to eu-, it is also made up of kata (down), and strophe (turning). Thus, literally, “a good down-turning”. Nevertheless, I added this word because it was coined by the well-known author J. R. R. Tolkien.
This word was first used in 1944
