Yesterday's Puzzle + Solution

Today's puzzle comes from Jason, who asks what these (and only these) letters have in common: F, H, L, M, N, Q*, R, S, U*, W, X, Y.

I've asterisked two letters whose inclusion is debatable.

Hint It has to do with the names of the letters.

Solution Jason says the puzzle was inspired by the question "Does 'W' begin with D?" These were the letters whose names don't start with a sound made by that letter. (You can probably see why Q and U are debatable. In particular, U starts with a consonant "Y" sound, but there are lots of words like unit in which the U makes the full "yoo" sound, just like its name.) (We'll say nothing of the British dialects in which H is pronounced "haitch".)

Congratulations to yesterday's solvers, Atticus and the Greggs. Thanks to everybody who made a guess!

About This Site

Though he now teaches mathematics, Dr. (né Mr.) Shapiro's first job in a K–12 school was as a lunch monitor in Davis, CA. It was there that he originated the Puzzle of the Day, even rewarding correct answers with tickets in denominations like "15 points" (though without a clear idea of how he'd ultimately redeem these). Dr. Shapiro's favorite puzzle from this pre-professional era was "Tell me the location of the beehive on this campus."

Ten years later, Dr. Shapiro revived Puzzle of the Day at Proof School, writing each day's puzzle on a name tag. After 600 puzzles or so, he was just starting to feel normal about students reading his chest all the time when campus closed and the puzzle, like the rest of our lives, moved online. New puzzles are posted daily on school days.
