This full-sized 15x puzzle is a clue/answer switch theme on some common “crosswordese”.
Likely too ‘inside baseball’ for publication, I had some fun coming up with the theme entries and putting the grid together.
Fun fact: this is the first 15×15 puzzle I’ve published online! I first constructed it in the heady pre-Coronavirus days of late-2019 and completed it in March 2020! It has languished in my drafts folder ever since. You can solve on pdf if you like.
