Coward accepts battlefront award in Stockholm (5)
I believe the answer is:
nobel
'award in stockholm' is the definition.
The definition suggests a singular noun which matches the answer.
'coward accepts battlefront' is the wordplay.
'coward' becomes 'noel' (playwright Noel Coward).
'accepts' means one lot of letters goes inside another.
'battlefront' becomes 'b' (this might be a standard abbreviation which I don't know about).
'noel' placed around 'b' is 'NOBEL'.
Can you help me to learn more?
(Other definitions for nobel that I've seen before include "6 24 113 [SCAN-DIN-AVIAN] chemist" , "Dynamite inventor, Prize founder" , "Swedish prize" , "Philanthropic Swede noted for establishing international prizes" , "Source of prizes" .)
