I'm on licence in various places (6)
I believe the answer is:
passim
'in various places' is the definition.
('passim' means 'in various places' in Latin)
'i'm on licence' is the wordplay.
'on' means one lot of letters go next to another.
'licence' becomes 'pass' (pass can mean a licence or permit).
'im' after 'pass' is 'PASSIM'.
(Other definitions for passim that I've seen before include "(Lit.) throughout, everywhere" , "(Of references) at various places through the text" , "At many points in book" , "Throughout (a piece of writing) - frequently cited" .)
