Dosh dished out by son in old fine (5)
I believe the answer is:
purse
'dosh' is the definition.
Both the definition and answer are singular nouns.
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 purse that I've seen before include "bag for loose change" , "Prize money - prepare to whistle" , "Sum of money as a prize - in pouch?" , "Compress (lips)" , "Money bag; pucker" .)
