Accused of sort of language used by young delinquent (8)
I believe the answer is:
indicted
'accused' is the definition.
(indicting is a kind of accusing)
'sort of language used by young delinquent' is the wordplay.
'sort of language' becomes 'indic' ().
'used by' is a charade indicator (letters next to each other).
'young delinquent' becomes 'ted' (member of the Teddy Boy subculture).
'indic'+'ted'='INDICTED'
'of' acts as a link.
(Other definitions for indicted that I've seen before include "Accused formally of a crime" , "Formally charged with a crime" .)
