This just might be the best made up word in an SF novel, ever. Neal Stephenson in Reamde used the word, “Apostropocalypse” to describe a dreaded event that caused the collapse of apostrophes throughout a fantasy game world, forever altering that world’s typography. Given how annoyed I get with fantasy names over-laden with apostrophes, I fully support the concept of an apostropocalypse. It should happen more often, frankly.
Still, I recognize that some of you might have your own candidates for best invented word in an imaginative work. Come forth, fellow logophiles! Share your favorites here, and we’ll discuss them.
