Damaged by popular success? (3)
I believe the answer is:
hit
'popular success?' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for hit that I've seen before include "Of a play, a smashing success" , "Successful record/film" , "Thump" , "Popular record" , "Visit to website" .)
