Short of funds, one can still have a good time (3)
I believe the answer is:
fun
'a good time' is the definition.
(I've seen this in another clue)
'short of funds one' is the wordplay.
'short of' suggests taking the first letters (I've seen 'short' mean this).
'one' becomes 'un' (northern English dialect form of 'one').
The first letter of 'funds' is 'f'.
'f'+'un'='FUN'
'can still have' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for fun that I've seen before include "Entertaining" , "'Merriment, playfulness (3)'" , "Jollification" , "Playful amusement" , "Light-hearted amusement, jollity" .)
