Maybe overcharged for a pup? (4)
I believe the answer is:
sold
'maybe overcharged' is the definition.
The definition and answer can be both to do with ownership as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sold that I've seen before include "Traded" , "Disposed of for money" , "Pushed" , "Betrayed for money" , "Exchanged for money" .)
