Debut! And with Brad!
Brad Wilber is such a great guy and the former editor of the Chronicle of Higher Education's crossword, which sadly ended a few years ago. He was perfect for that job since he's an incredibly smart person who can pull out terms like MONONYM that are not only interesting but accessible. I have a terrible time keeping those -NYM terms straight, but the MONO prefix makes this one easier.
Will Shortz is extremely picky about "hidden words" themes these days because they've become overdone. Today's features one incredible find, EMINEM in MINE MINE MINE! Some solvers might wonder if that phrase is legit, but those solvers don't have kids.
The other discoveries aren't as mind-blowing because four-letter hidden words aren't as impressive. It does help if there's a rare(ish) letter like a K, and SPIN KICK is a vivid phrase. CARBON OFFSET is a modern term. It's harder to hide ENYA than you might think. Still, these three don't have the wow factor of EMINEM's six letters.
I also want a perfect revealer for hidden words puzzles, and while MONONYM does describe what's going on, it doesn't give a rationale for hiding the names. MIDDLE NAMES would sort of do it, but that doesn't get at the one-nameness. I don't think there is a perfect revealer, unfortunately, which is a ding on this theme concept.
Another approach was to disguise one-named singers.
I appreciated the huge number of clever or fun clues. My favorite was [Body part where a shoe goes]. Probably like most everyone, I filled in FOOT, especially when the middle OO worked fine. Fun head-slap when I realized it referred to a horse's shoe.
A couple of rough patches in the grid, a bit of ELEV HELI, and SLUE is tough vocab. I've learned SIENA from crosswords, but if you haven't traveled to Tuscany, that might be a head-scratcher. Fair crossings for everything, though, and some might appreciate learning something new.
Not my favorite hidden words puzzle, but that EMINEM find was fantastic.
