How interesting! It certainly looks like Yam, but when I look at it with a magnifying glass, it is an artifact of the way the font was rendered by the printer, and it is indeed Yarn.
Evidently, this must be a common problem, as in the crossword solvers, the entry is for Yam, not Yarn, yet Tale is in the answers:
crossword-solver/yam
crossword-solver.io/ clue/ yam./
Thank you for solving this mystery.
