...sketch artist upset by small prizes (7)
I believe the answer is:
rewards
'prizes' is the definition.
(I know this)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for rewards that I've seen before include "Recompenses" , "Gifts of appreciation" , "Payments made as marks of appreciation" , "Gifts given in acknowledgement of behaviour or merits" , "Prizes or remunerations" .)
