Slogs wildly, but not without polish (5)
I believe the answer is:
gloss
'polish' is the definition.
(I know that polish can be written as gloss)
'slogs wildly but not without' is the wordplay.
'slogs' can be anagrammed to 'GLOSS'.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for gloss that I've seen before include "High shine" , "Very shiny finish" , "phrase's explanation" , "marginal note" , "Superficial shine" .)
