On reflection, get conservatory tiled if they can show faithful accuracy in reproducing the original (8)
I believe the answer is:
fidelity
'they can show faithful accuracy in reproducing the original' is the definition.
The definition suggests an adverb but the answer is not.
'on reflection get conservatory tiled if' is the wordplay.
'on reflection' is a reversal indicator.
'get conservatory' becomes 'y' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'y'+'tiled'+'if'='ytiledif'
'ytiledif' written backwards gives 'FIDELITY'.
Can you help me to learn more?
(Other definitions for fidelity that I've seen before include "Tidy file (anag)" , "Loyalty" , "Devotion" , "Honesty" , "Faithfulness" .)
