Auctioneer's last word (4)
I believe the answer is:
sold
'auctioneer's last word' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sold that I've seen before include "Flogged" , "Handed over for money" , "Exchanged for money" , "Persuaded" , "Pushed" .)
