Lines recited say in cathedral (5)
I believe the answer is:
elegy
'lines' is the definition.
(I've seen this before)
'say in cathedral' is the wordplay.
'say' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'in' indicates putting letters inside.
'cathedral' becomes 'ely' (cathedral city in Cambridgeshire).
'eg' going into 'ely' is 'ELEGY'.
'recited' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for elegy that I've seen before include "Plaintive poem" , "Mournful song or poem" , "Poetic lament for the dead" , "Poetic lament (in a country churchyard?)" , "Poem as Gray's in churchyard" .)
