"Gone With the Wind" star Clark (5)
I believe the answer is:
gable
'gone with the wind star clark' 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 "Triangular top of side wall" , "Part of house" , "Old actor" , "Section of wall between roof slopes" , "Triangular brickwork" .)
