Playwright admits art unrefined (9)
I believe the answer is:
dramatist
'playwright' is the definition.
(I know that playwright can be written as dramatist)
'admits art unrefined' is the wordplay.
'admits art' anagrams to 'DRAMATIST'.
Though, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for dramatist that I've seen before include "Coward, for example" , "Coward perhaps" , "One who writes plays" , "man of theatre" , "Playwright" .)
