What makes Oxford look bright? (9)
I believe the answer is:
shoeshine
'what makes' is the definition.
I can't judge whether this defines the answer.
'oxford look bright?' is the wordplay.
'oxford' becomes 'shoe' (I've seen this in another clue).
'look bright?' becomes 'shine' (I can't justify this - if you can you should give a lot more credence to this answer).
'shoe'+'shine'='SHOESHINE'
Can you help me to learn more?
(Other definitions for shoeshine that I've seen before include "polish" , "Footwear polishing (US)" , "Footwear cleaning (US)" .)
