Show a film about partition? (6)
I believe the answer is:
screen
I believe this is a double definition.
'show a film' is the first definition.
(I've seen this before)
'partition?' is the second definition.
(I know that screen is a type of partition)
'about' acts as a link.
(Other definitions for screen that I've seen before include "Room divider" , "Blind - hide from view" , "Hide - show - partition" , "not to show? That's a riddle" , "Examine for suitability, sift" .)
