This comes from my buddy Tony:
Specify a word that cannot be played under any circumstances in a Scrabble game.
Feel free to look up Scrabble rules if you need a refresher (or ask me). Googling “unplayable Scrabble words” is not allowed, of course. Send your answers to me privately and I’ll post them in a few days — there’s more than one right answer. Also, no words allowed that are clearly excluded by Scrabble rules (proper nouns, foreign words, etc.).
If you’d like to see some of the possible answers, check out the next post.
