Charm — captivate (6)
I believe the answer is:
ravish
I believe this clue is a double definition.
'charm' is the first definition.
(thesaurus)
'captivate' is the second definition.
(I've seen this in another clue)
(Other definitions for ravish that I've seen before include "Seize and carry off" , "Enchant" , "Enrapture - sexually assault" , "Seduce" , "Rape" .)
