Trump wants one head of BBC arrested by Christmas (5)
I believe the answer is:
nobel
'trump' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?
'one head of bbc arrested by christmas' is the wordplay.
'one head of' indicates taking the first letters.
'arrested by' means one lot of letters goes inside another (inserted letters are held or arrested).
'christmas' becomes 'Noel' (Noel can mean Christmas).
The first letter of 'bbc' is 'b'.
'b' going inside 'noel' is 'NOBEL'.
'wants' acts as a link.
Can you help me to learn more?
(Other definitions for nobel that I've seen before include "and 21 Across: Prestigious international award" , "Prize-endowing Swedish chemist" , "Philanthropic Swede noted for establishing international prizes" , "Founder of many prizes" , "Prize guy" .)
