Film doctor and nurse then go private (2,5)
I believe the answer is:
no entry
'private' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'film doctor and nurse then go' is the wordplay.
'film doctor' becomes 'no' (I can't justify this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'nurse' becomes 'EN' (abbreviation for state-enrolled nurse).
'then' means one lot of letters go next to another.
'go' becomes 'try' (both can mean an attempt).
'no'+'en'+'try'='NO ENTRY'
Can you help me to learn more?
(Other definitions for no entry that I've seen before include "Admittance prohibited!" , "street sign" .)
