Criticises puzzles, getting wrong end of stick (7)
I believe the answer is:
rebukes
'criticises' is the definition.
(rebuking is a kind of criticizing)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for rebukes that I've seen before include "Expresses sharp disapproval" , "Strong reprimands" , "Admonishes, chides" , "Admonishes sharply or severely" .)
