See Miss Phillips being heavenly? (7)
I believe the answer is:
elysian
'heavenly?' is the definition.
(I've seen this before)
'see miss phillips' is the wordplay.
'see' becomes 'ely' (see is a place with a cathedral - e.g. Ely).
'miss phillips' becomes 'sian' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ely'+'sian'='ELYSIAN'
'being' acts as a link.
Can you help me to learn more?
(Other definitions for elysian that I've seen before include "Like paradise" , "of the most beautiful fields" , "Any isle (anag.)" , "glorious" , "Of abode of the blessed dead in Greek mythology" .)
