Charm one's way in (8)
I believe the answer is:
This clue might be a double definition.
'charm one's' is the first definition.
'entrance' can be an answer for 'charm' ('entrance' can be a synonym of 'charm'). I am unsure of the 'one's' bit.
'way in' is the second definition.
Can you help me to learn more?
(Other definitions for entrance that I've seen before include "it's common, say, for some children to sit" , "Gate" , "Bowl over" , "Vestibule" , "Captivate on way in ?" .)
