Exonerated over an eyesore perhaps - how perceptive is that? (12)
I believe the answer is:
'how perceptive is that?' is the definition.
I can't judge whether this definition defines the answer.
'exonerated over an eyesore' is the wordplay.
'exonerated' becomes 'cleared' (synonyms).
'over' indicates putting letters inside.
'an eyesore' becomes 'sight' (I've seen this before).
'cleared' going around 'sight' is 'CLEARSIGHTED'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for clear-sighted that I've seen before include "Perspicacious" , "Discerning" , "Perceptive" .)
