Fine stonework in church choir finally covered by board (7)
I believe the answer is:
tracery
'fine stonework' is the definition.
'tracery' can be an answer for 'stonework' (I have seen 'Ornamental stonework ' mean 'tracery' so perhaps 'stonework' could also mean 'tracery'). I am unsure of the 'fine' bit.
'church choir finally covered by board' is the wordplay.
'church' becomes 'ce' (Church of England).
'finally' indicates one should take the final letters.
'covered by' indicates putting letters inside.
'board' becomes 'tray' ().
The last letter of 'choir' is 'r'.
'ce'+'r'='cer'
'cer' going inside 'tray' is 'TRACERY'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for tracery that I've seen before include "Thin ribs of e.g. Gothic window" , "Honks; Florence Dombey admirer (Dickens)" , "Fine open stonework" , "Delicate stone work" , "Ornamental stone work" .)
