See from inside Lyceum (3)
I believe the answer is:
ely
'see' is the definition.
(see is a place with a cathedral - e.g. Ely)
'from inside lyceum' is the wordplay.
'from' says the answer is hidden in the clue.
'ELY' is hidden within 'inside lyceum'.
(Other definitions for ely that I've seen before include "Cathedral city in Cambridgeshire" , "See" , "Cathedral city in East Anglia" , "UK city" , "Small city in Cambridgeshire" .)
