NPR Sunday Puzzle (Mar 23, 2025): TH: Think vs. ThatQ: In English the two-letter combination TH can be pronounced in two different ways: once as in the word "booth," the other as in "smooth." What is the only common English word, other than "smooth," that ends in the letters TH as pronounced in smooth?
I can't be the only one that is having trouble in clueing the answer to this puzzle. That's assuming you aren't already having trouble in hearing the distinction between an unvoiced and voiced dental fricative.
Edit: I wasn't sure if the intended answer was WITH or MOUTH (verb). I had to work to not include WITH in my clue. And often when you MOUTH something, you don't use your voice. I agree there can be other valid answers like BETROTH, BEQUEATH, etc.
A: MOUTH (verb)
