In the May 1995 issue of Word Ways, I drew your attention to one of the problem words of the English language, SERICON, and proposed a tongue-in-cheek solution. Now, wearing a more serious hat, I -ish to mention two other literary grey areas and appeal to you for help in clarifying the situation. In addition to the mystery of SERICON, Pears Advanced Word-Puzzler's Dictionary (Pelham Books, 1987) also confessed ignorance in two of its other entries; I quote directly from pages 574 and 749, respectively.
