Compensated for having given material assistance (6)
I believe the answer is:
repaid
'compensated for' is the definition.
'repaid' can be an answer for 'compensated' (I've seen this in another clue). I'm unsure of the 'for' bit.
'given material assistance' is the wordplay.
'given' is a charade indicator (letters next to each other).
'material' becomes 'rep' (rep is a kind of material).
'assistance' becomes 'aid' (synonyms).
'rep' next to 'aid' is 'REPAID'.
'having' is the link.
Can you help me to learn more?
(Other definitions for repaid that I've seen before include "Refunded or rewarded" , "Recompensed" , "no longer outstanding" , "Returned" , "Gave back money owed" .)
