Playwright has inspired a creative type (7)
I believe the answer is:
painter
'creative type' is the definition.
(painter is a type of artist)
'playwright has inspired a' is the wordplay.
'playwright' becomes 'pinter' (Harold Pinter).
'has inspired' is an insertion indicator (inserted letters are breathed in or \'inspired\').
'pinter' placed around 'a' is 'PAINTER'.
(Other definitions for painter that I've seen before include "a line connected to a boat" , "Artist; decorator" , "What Rolf Harris was allowed to do" , "Cougar" , "someone like Monet" .)
