Juvenile boozer skinned her nose (9)
I believe the answer is:
pubescent
'juvenile' is the definition.
(thesaurus)
'boozer skinned her nose' is the wordplay.
'boozer' becomes 'pub' (UK slang).
'skinned' indicates the central letters.
'nose' becomes 'scent' (synonyms).
The central letter of 'her' is 'e'.
'pub'+'e'+'scent'='PUBESCENT'
(Other definitions for pubescent that I've seen before include "Young" , "Getting down" , "Just beginning sexual maturity" , "Approaching a teenager" .)
