Spades, not new, get auctioned (4)
I believe the answer is:
sold
'auctioned' is the definition.
The answer and definition can be both to do with ownership as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'spades not new' is the wordplay.
'spades' becomes 's' (abbreviation in card games).
'not new' becomes 'old' ('old' is the opposite to 'new').
's'+'old'='SOLD'
'get' acts as a link.
Can you help me to learn more?
(Other definitions for sold that I've seen before include "Retailed" , "Exchanged for money" , "Handed over for money" , "Betrayed for money" , "Persuaded" .)
