Not originally bound for Norway after drinking ale up (8)

'not originally bound' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can sometimes mean the same thing.

'for norway after drinking ale up' is the wordplay.
'norway' becomes 'n'.
'after drinking' means one lot of letters goes inside another.
'ale' becomes 'beer' (ale is a type of beer).
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'beer' in reverse letter order is 'reeb'.
'for'+'n'='forn'
'forn' enclosing 'reeb' is 'FREEBORN'.
