Charming about damage (4)
I believe the answer is:
harm
'damage' is the definition.
(I know that damage can be written as harm)
'charming about' is the wordplay.
'about' says the answer is hidden in the clue (the clue goes around or about the answer).
'HARM' is hidden within 'charming'.
(Other definitions for harm that I've seen before include "Hurt, maim" , "Trials, exams" , "Injure, injury" , "Injure or damage" , "Hurt, injure" .)
