"Pygmalion" playwright (4)
I believe the answer is:

'pygmalion 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" , "writer of plays and critical commentaries" , "Thicket; playwright" , "Irish playwright, d. 1950" , "Man and Superman playwright" .)
