Butler's portrayer (5)
I believe the answer is:
gable
'butler's portrayer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gable that I've seen before include "American actor" , "Part of outer wall - actor, Clark" , "Old actor" , "Triangular upper part of a wall under a roof" , "Filmstar at the side of the house?" .)
