Trump clan rejected countercultural figure (7)
I believe the answer is:
beatnik
'countercultural figure' is the definition.
I can't tell whether this definition defines the answer.
'trump clan rejected' is the wordplay.
'trump' becomes 'beat' (trump can mean to beat or outdo).
'clan' becomes 'kin' (synonyms).
'rejected' says the letters should be written in reverse.
'kin' reversed gives 'nik'.
'beat'+'nik'='BEATNIK'
Can you help me to learn more?
(Other definitions for beatnik that I've seen before include "Young person of the 1950s, nonconformist in dress and behaviour" , "Rebellious youth (dated)" , "eg Jack Kerouac" , "Unconventional young scruff" , "Disaffected 50s youth" .)
