Really, this is just an excuse to have an entry under q. But here, for what it's worth, are the valid Scrabble words with a q but no u, that I am able to think of off the top of my head on March 1, 2007. If you want a definitive list, you should probably look elsewhere.

• qwerty
• tranq
• sheqel
• qat
• qaid

Yeah, definitely look elsewhere.
