New English author (6)
I believe the answer is:
greene
'author' is the definition.
(I've seen this before)
'new english' is the wordplay.
'new' becomes 'green' (I've seen this in another clue).
'english' becomes 'e' (abbreviation).
'green'+'e'='GREENE'
(Other definitions for greene that I've seen before include "Graham -, twentieth century English author" , "Graham --, Eng. author" , "Graham -, English novelist" , "writer" , "The Quiet American author" .)
