Draught excluder with pictures on (6)
I believe the answer is:
screen
'draught excluder' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'pictures on' is the wordplay.
I cannot quite understand how this works, but
'on' could be 're' ('on' can be mean 'with reference to') and 're' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'with' acts as a link.
Can you help me to learn more?
(Other definitions for screen that I've seen before include "Standing partition" , "Censer (anag.)" , "Shield - broadcast" , "Surface for projection of pictures" , "Surface on which to project pictures" .)
