Lovely cathedral (3)
I believe the answer is:
ely
'lovely cathedral' is the definition.
'ely' can be an answer for 'cathedral' (cathedral city in Cambridgeshire). I'm not sure about the 'lovely' bit.
'lovely cathedral' is the wordplay.
'ELY' is hidden within the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for ely that I've seen before include "Diocese in Eastern England" , "Fenland city" , "Cambs. city" , "Fenland cathedral town" , "'Isle' in Cambridgeshire" .)
