Enjoyment to be had with daughter in pool (4)
I believe the answer is:
fund
'daughter in pool' is the definition.
'fund' can be an answer for 'pool' (I've seen this before). I'm not sure about the 'daughter in' bit.
'enjoyment to be had' is the wordplay.
'enjoyment' becomes 'fun' (I've seen this in another clue).
'to be had' becomes 'd' (I've seen this in other clues).
'fun'+'d'='FUND'
'with' is the link.
Can you help me to learn more?
(Other definitions for fund that I've seen before include "Reserve of money for future use" , "Stock, resources" , "Give money" , "Finance" , "Supply cash" .)
