Nurse has right permit (7)
I believe the answer is:
entitle
'permit' is the definition.
(I've seen this in another clue)
'nurse has right' is the wordplay.
'nurse' becomes 'en' (abbreviation for enrolled nurse).
'has' is a charade indicator (letters next to each other).
'right' becomes 'title' (title is a kind of right).
'en'+'title'='ENTITLE'
(Other definitions for entitle that I've seen before include "Name; enable" , "confer rank" , "Licence" , "Name, authorise" , "Give one the right - name" .)
