Object of worship serious sorcerer keeps nuts in (6,5)
I believe the answer is:
graven image
'object of worship' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'serious sorcerer keeps nuts in' is the wordplay.
'serious' becomes 'grave' (both can mean solemn).
'sorcerer' becomes 'mage' (I've seen this in other clues).
'keeps' means one lot of letters goes inside another (inserted letters are kept inside).
'nuts' indicates an anagram (nuts can mean crazy).
'grave'+'mage'='gravemage'
'in' is an anagram of 'ni'.
'gravemage' placed around 'ni' is 'GRAVEN IMAGE'.
Can you help me to learn more?
(Other definitions for graven image that I've seen before include "Idolised figure" , "Sculpted idol" , "Revered figure" , "Glorified carving" .)
