"Arms and the Man" playwright (4)
I believe the answer is:
shaw
'arms and the man playwright' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for shaw that I've seen before include "Pygmalion playwright" , "George Bernard -, Irish dramatist" , "Major Barbara playwright" , "Irish playwright, d. 1950" , "writer of plays and critical commentaries" .)
