I have a nifty little book called, The Gilded Tongue. My son, Alex, and I used to read from it frequently, taking delight in its absurdly pompous words. Sample:
Malison (MAL-uh-suhn): n. from Middle English malisoun, from Old French, from Latin maledictio, from maledictus, past participle of maledicere (to speak ill): a curse.
John hated Paul so much that he called down a malison on him.
