Chicken — playwright (6)
I believe the answer is:
coward
I believe this is a double definition.
'chicken' is the first definition.
(similar in meaning)
'playwright' is the second definition.
(Noel Coward)
(Other definitions for coward that I've seen before include "Gutless type" , "Craven type" , "Author of 'Blithe Spirit'" , "writer and composer" , "Person without courage" .)
