Mint drink, with note in it (5-3)
I believe the answer is:
brand-new
'mint' is the definition.
(thesaurus)
'drink with note in it' is the subsidiary indication.
'drink' becomes 'brew' (brew is a kind of drink**).
'with' becomes 'and'.
'note' becomes 'n' (abbreviation).
'in it' indicates putting letters inside.
'and'+'n'='andn'
'brew' enclosing 'andn' is 'brandnew'.
(Other definitions for brand-new that I've seen before include "Ultra modern" , "Completely unused" , "Completely fresh" , "Hot off the production line" , "Pristine, never been used" .)
