Free pardon rejected: hanging seen inside! (5)
I believe the answer is:
drape
'hanging seen inside' is the definition.
'drape' can be an answer for 'hanging' (I've seen this before). I am not sure about the 'seen inside' bit.
'free pardon rejected' is the wordplay.
'DRAPE' is hidden back-to-front within the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for drape that I've seen before include "Swathe" , "Cover loosely for padre" , "Hang - curtain" , "Hang (cloth) loosely" , "Loose fabric cover" .)
