Loganamnosis

"n. A mania for trying to recall forgotten words. Do you remember ‘lethologica’ - inability to recall words - from this book’s predecessor, The Superior Person’s Book of Words? Well, you wouldn’t,would you, if you suffered from it. But in any event the present word goes rather beyond that; loganamnosis is the compulsive perseverance of alethologiac to summon up that elusive memory - that maddening word that’s‘on the tip of my tongue.’ Most people give up after a few minutes; the loganamnostic reduces himself or herself to a neurotic case study in the attempt."
