Having no French polish! (6)
I believe the answer is:
gauche
'polish' is the definition.
Although both the answer and definition are adjectives, I cannot see how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for gauche that I've seen before include "Lacking ease of manner (from the French)" , "careless" , "Unsophisticated and socially awkward" , "Socially awkward or tactless" , "Graceless" .)
