Sketch artist perhaps lifting prize (6)
I believe the answer is:
reward
'prize' is the definition.
(a prize may be given as a reward)
'sketch artist perhaps lifting' is the wordplay.
'sketch' becomes 'draw' (to sketch is to draw).
'artist perhaps' becomes 'er' (I can't explain this - if you can you should believe this answer much more).
'lifting' shows that the letters should be reversed in order.
'draw'+'er'='drawer'
'drawer' in reverse letter order is 'REWARD'.
Can you help me to learn more?
(Other definitions for reward that I've seen before include "Drawer (anag.)" , "Present given to mark service or good deed" , "It's given for service or attainment" , "Bounty; recompense" , "Appreciative gift offered for drawer" .)
