Youngster wanting good story book tucked into treat and drink (3,8)
I believe the answer is:
cub reporter
'youngster wanting good story' is the definition.
I can't tell whether this definition defines the answer.
'book tucked into treat and drink' is the wordplay.
'book' becomes 'b' (abbreviation for book).
'tucked into' is an insertion indicator.
'treat' becomes 'cure' (as in medical treatment).
'and' is a charade indicator (letters next to each other).
'drink' becomes 'porter' (porter is a kind of drink).
'b' inserted inside 'cure' is 'cubre'.
'cubre'+'porter'='CUB REPORTER'
Can you help me to learn more?
(Other definitions for cub reporter that I've seen before include "Inexperienced journalist" , "Trainee journalist" .)
