When you get paid too much, this can make things look better (8)
I believe the answer is:
makeover
'when you get paid' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'too much this can make things look better' is the wordplay.
I cannot really see how this works, but
'better' could be 'make' (synonyms) and 'make' is located in the answer.
'too much' could be 'over' (I've seen this before) and 'over' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for makeover that I've seen before include "completely changing how someone looks" , "Reconstruction" , "cosmetic treatment" .)
