It might provide something pleasurable when in debt? (6)
I believe the answer is:
refund
'it might provide something' is the definition.
The definition suggests a singular noun which matches the answer.
'pleasurable when in debt?' is the wordplay.
'pleasurable' becomes 'fun' (I've seen this in another clue).
'when in' indicates putting letters inside.
'debt?' becomes 'red' ('in the red' means 'in debt').
'fun' going inside 'red' is 'REFUND'.
Can you help me to learn more?
(Other definitions for refund that I've seen before include "Give back" , "Cash back" , "money to be paid back" , "Money returned" .)
