Do better than another bootblack? (8)
I believe the answer is:
outshine
'do better' is the definition.
'outshine' can be an answer for 'better' (I've seen this before). I am not certain of the 'do' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for outshine that I've seen before include "Eclipse" , "Surpass in splendour like the sun" , "beat" , "Display area for goods" , "give more light, paradoxically" .)
