Charming with member (3)
I believe the answer is:
arm
'member' is the definition.
(member can mean a limb)
'charming with' is the wordplay.
'with' says the answer is hidden in the clue.
'ARM' can be found hidden inside 'charming'.
(Other definitions for arm that I've seen before include "Limb or branch" , "Part of chair" , "Steel" , "Shoulder to fingertip" , "Division of company" .)
