Normandy favourite arrived right on time to receive honour (9)
I believe the answer is:
camembert
'normandy favourite' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'arrived right on time to receive honour' is the wordplay.
'arrived' becomes 'came' (come can mean to appear or arrive).
'right' becomes 'r' (abbreviation).
'on time' becomes 't' (abbreviation. I am not sure about the 'on' bit.).
'to receive' is an insertion indicator.
'honour' becomes 'MBE' (Member of the British Empire award).
'came'+'r'+'t'='camert'
'camert' enclosing 'mbe' is 'CAMEMBERT'.
Can you help me to learn more?
(Other definitions for camembert that I've seen before include "Soft creamy French cheese" , "soft fare" , "For something to eat" , "French produce" , "French food" .)
