"Arms and the Man" playwright
I believe the answer is:
'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" .)
