Slogs wildly, yet with a certain polish (5)
I believe the answer is:
gloss
'polish' is the definition.
(I know that gloss is a kind of polish)
'slogs wildly yet with a certain' is the wordplay.
'slogs' can be anagrammed to 'GLOSS'.
Though, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for gloss that I've seen before include "Superficial appearance" , "Superficial shine" , "Sheen - paint" , "Render plausible" , "Shiny surface" .)
