British newspaper to make self-aggrandising claims (4)
I believe the answer is:
brag
'make self-aggrandising claims' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'british newspaper' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'newspaper' becomes 'rag' (informal term for a newspaper).
'b'+'rag'='BRAG'
'to' is the link.
Can you help me to learn more?
(Other definitions for brag that I've seen before include "Talk boastfully" , "Blow one's own trumpet" , "Idle talk" , "'Show off, boast (4)'" , "popular with 15 [EGOTIST] , no doubt" .)
