Mr. Fatsis was interviewed on Saturday Weekend Edition on NPR about this book. I have emailed Mr. Fatsis in care of Weekend Edition. The following is the text of my email.
Dear Mr. Fatsis
The matter of your book on Scrabble® came up on a message board I frequent, particularly in reference to the purported word "abceghilnoprtuy". The common belief that we have decided upon is that the word has no meaning and was just a vaguely pronounceable collection of unrepeated letters in alphabetical order (and we have some serious word experts, including one who has a daily email with the worthless word for the day). If you can disabuse us of this notion we would appreciate it. If we are spot on we would appreciate knowing that, too.
