Red rose transformed decoration in church (7)
I believe the answer is:
reredos
'decoration in church' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'red rose transformed' is the wordplay.
'transformed' indicates anagramming the letters.
'red'+'rose'='redrose'
'redrose' anagrammed gives 'REREDOS'.
Can you help me to learn more?
(Other definitions for reredos that I've seen before include "Painted screen behind an altar" , "Wall decoration behind altar" , "Ornamental screen behind a church altar" , "Hanging in church" , "Red rose could show a screen behind the altar" .)
