About to suppress hesitation with computer system for screen in church (7)
I believe the answer is:
reredos
'screen in church' is the definition.
(I've seen this before)
'about to suppress hesitation with computer system' is the wordplay.
'about' is a reversal indicator.
'to suppress hesitation with' becomes 'erer' (I can't explain this - if you can you should give a lot more credence to this answer).
'computer system' becomes 'dos' (I've seen this in another clue).
'erer' reversed gives 'rere'.
'rere'+'dos'='REREDOS'
'for' is the link.
Can you help me to learn more?
(Other definitions for reredos that I've seen before include "Red rose could show a screen behind the altar" , "Fireback" , "Back of fireplace" , "Painted screen behind an altar" , "Wall decoration behind altar" .)
