Sabotage in a charming way (4)
I believe the answer is:
harm
'sabotage' is the definition.
(thesaurus)
'in a charming way' is the wordplay.
'in' indicates a hidden word.
'HARM' is hidden within 'charming way'.
(Other definitions for harm that I've seen before include "Injure, injury" , "Short-long metric feet" , "See 13" , "Damage, hurt" , "Injure or damage" .)
