One of the splendors of our world is that there's so much to be terrified of. But most of us stick with common, run-of-the-mill fears that come close to boring (rather than scaring) us silly. This deck of 48 Knowledge Cards presents a surprising and delightful smorgasbord of irrational dread. One side of each card introduces one to four words related to unusual phobias, with a sentence showing their correct usage. The opposite side gives their definitions and pronunciation. You'll learn of things you never thought to be afraid of--and happily recognize long-undetected phobias of your own. Best of all: reading Phobias to your friends may give them hilarious panic attacks (don't try this if you're a hedonophobe). Charles Harrington Elster is the author of There's a Word for It! (excerpted in this deck), Verbal Advantage, and other books about words.
