Church canon with a new description of the heavens? (8)
I believe the answer is:
cerulean
'description of the heavens?' is the definition.
'cerulean' can be an answer for 'heavens?' (thesaurus). I'm unsure of the 'description of the' bit.
'church canon with a new' is the wordplay.
'church' becomes 'CE' (abbreviation for Church of England).
'canon' becomes 'rule' (canon can mean a rule or principle).
'with' is a charade indicator (letters next to each other).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'ce'+'rule'+'a'+'n'='CERULEAN'
Can you help me to learn more?
(Other definitions for cerulean that I've seen before include "Light shade of blue" , "Blue like the sky" , "Sky-blue in literary way" , "Sky-blue for Laurence" , "Deep blue colour" .)
