Charm, possibly earned (6)
I believe the answer is:
endear
'charm' is the definition.
(I've seen this before)
'possibly earned' is the wordplay.
'possibly' indicates anagramming the letters.
'earned' with letters rearranged gives 'ENDEAR'.
(Other definitions for endear that I've seen before include "ingratiate" , "Earned (anag.)" , "Make lovable or please" , "Make loveable" , "Draw" .)
