A place for hanging painting only the last character permits (7)
I believe the answer is:
gallows
'a place' is the definition.
(I have seen 'Place of execution ' mean 'gallows' so perhaps 'place' could also mean 'gallows')
'character permits' is the wordplay.
'character' becomes 'g' ().
'permits' becomes 'allows' ('allow' can be a synonym of 'permit').
'g'+'allows'='GALLOWS'
'for hanging painting only the last' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for gallows that I've seen before include "suspender" , "Gibbet" , "Here one may end" , "tree" , "5 dn [GRIM REAPER] might appear here" .)
