Talk to allow returning piece of personal property (7)
I believe the answer is:
chattel
'personal property' is the definition.
(chattel is a kind of personal property)
'talk to allow returning' is the wordplay.
'talk' becomes 'chat' (I've seen this before).
'to allow' becomes 'let' ('let' can be a synonym of 'allow').
'returning' shows that the letters should be reversed in order.
'let' in reverse letter order is 'tel'.
'chat'+'tel'='CHATTEL'
'piece of' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for chattel that I've seen before include "Piece of portable property" , "Personal possession" , "Item of personal property" , "Item of non-freehold property" , "Movable possession" .)
