Playwright Coward (4)
I believe the answer is:
noel
'playwright coward' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for noel that I've seen before include "A lone French Christmas" , "Festive season" , "Another word for 7 Across" , "Xmas refrain" , "A lone sort of Christmas" .)
