Give one an order to paint? (8)
I believe the answer is:
decorate
'to paint?' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for decorate that I've seen before include "Award a medal to" , "Add ornamentation to" , "Honour" , "paint" , "Improve the look of" .)
