My bad review of successful chiropractic treatment (1,5,9)
I believe the answer is:
i stand corrected
'bad review of successful chiropractic treatment' is the definition.
The definition suggests an adjective which matches the answer.
'my' is the wordplay.
I cannot quite see how this works, but
'my' could be 'cor' (both are expressions of surprise) and 'cor' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for i stand corrected that I've seen before include "I'll give you that" , "Oops!" .)
